Europa is a remarkable ocean world, the smallest of the four Galilean satellites orbitting Jupiter, that continues to be the focus of intense scientific study. Europa may be the current best location to explore in search of life outside of Earth. In addition to the innumerable telescopic observations of Europa, many satellites have visited this intriguing world and captured a myriad of different types of data. It is from these data that we, research scientists, policy makers, and the interested public learn more about this distant world.
Each dataset collected with observations of Europa is a treasure in its own right. Collectively, these data sets provide a rich perspective from which we can learn about the past, present, and potential future for Europa. The desire for cross-data set interoperability and ease of data discovery were the impetus for the development of this Europa Spatial Data Infrastructure (SDI).
The Europa SDI is focused on the organization of spatial data. These data are identified, standardized, and made available so that you, the user, can discover, access, and use them more efficiently. Scientists from multiple different institutions have come together to develop and agree upon spatial standards and data interchange formats that support cross data set analyses.
For data providers, this means that we want to work together to make your data available to as broad a user base as possible. This includes helping build great documentation that describes your data, helping get that data to be standards compliant, and then finding a data host to serve that data over the web.
For data hosts, we want to work together to help you adopt OGC standards and serve data to widest possible user base. This means linking your data services into registries with other compliant data provider's services so that tool developers can build rich data portals and analysis environments for users.
Finally, we want to work with the user community to ensure that we are meeting their needs. Are appropriate data available and discoverable? Is documentation accessible and written at a level that makes data approachable?

## Summary
The Lunar Spatial Data Infrastructure team will evaluate existing spatial data and data standards for the moon and assess spatial data storage, acquisition, discovery, and use needs of the Lunar community. Spatial data infrastructure (SDI) is the enabling collection of spatial data users, data interoperability agreements, policies and standards, data access mechanisms, and the spatial data themselves (Rajabifard et al., 2002). The overarching goal of the Lunar SDI is to allow individuals that are not spatial data experts to use spatial data to the greatest extent possible, with the lowest possible overhead (Laura et al., 2018). This team will address complexities by defining policies and standards that will be applicable to this SDI regarding data interoperability, data contribution, and the long-term maintenance of this SDI for the benefit of all user communities.
## Objectives
Publish and steward the policy infrastructure necessary to maintain this SDI including this charter, user and contributor agreements to support data release and sharing agreements, and a roadmap map of future development.
Engage with the user community, funding agencies, and NASA Advisory Groups to ensure the efforts of this body maximally align with targeted user community needs.
- Publish and steward the policy infrastructure necessary to maintain this SDI, including a charter, governance documentation, user and contributor agreements support data release and sharing agreements, and a roadmap of future development.
- Engage with the user community, funding agencies, and NASA Advisory Groups to ensure the efforts of this body maximally align with targeted user community needs.
- Publish an initial set of standards that will define this SDI including standardized vertical and horizontal datums (i.e., the coordinate system), accepted map projections, interoperable data formats, and metadata formats.
- Maintain, in conjunction with the Lunar community, a living inventory of foundational and framework data products including quantitative (e.g., positional accuracy, resolution, data producer) and qualitative (e.g., fitness-for-use) metadata. This includes setting a standard for metadata to be reported for all data products managed under the Lunar SDI organization.
- Provide a mechanism to bring together users, such as data creators (who make the data products), custodians (who manage the data products lifecycle), and data integrators (who provide the data to end users) to create an interconnected user group.
- Support (through policies and standards) the development of data discovery and access portals making use of Lunar SDI managed data and associated Application Programming Interfaces (APIs).
- Ensure the public release of all Lunar SDI managed data products and APIs.
- Engage with tool developers to ensure support for data and standards included in the Lunar SDI.

**DRAFT**
## Data and Licensing Standards
Data and derived products within this SDI conform to a set of standards to maximize interoperability, including standardized vertical and horizontal datums (i.e., the coordinate system), accepted map projections, and metadata formats. Significant effort was made to use standards that are consistent with IAU recommendations, those in use by relevant mission teams, and that foster interoperability. See the Guidelines for Lunar Data Providers for detailed information regarding the standards and formats the Lunar SDI adheres to, with the goal of maximizing interoperability between datasets and reducing the need to reproject or reprocess data.
In addition, all data made publicly available through the Lunar SDI should use an open-data license. See the Guidelines for Lunar Data Providers for additional information regarding license guidance.

title: Governance Model
weight: 6
---
**DRAFT**
The Lunar SDI Working Group is governed through two complementary strategies: 1) regular working group meetings, and 2) asynchronous collaborations using email and a shared work drive.
## Meetings and Ratification of Minutes
The working group meets regularly (roughly monthly) using tools that enable participation by the community. We use a videoconferencing platform for our meetings. Working group members are expected to regularly participate in working group activities. The Chair sends a calendar invite to all working group members prior to the meeting. The Chair also sets the meeting agenda and runs the meeting unless they have delegated that role to another member or subject matter expert. Meetings are generally not recorded.
Items are added to the meeting agenda that require discussion, decisions to be made, or are modifications of governance, contribution policy, membership, or release process. Updates on efforts toward meeting strategic plan goals are also discussed and reviewed in meetings. Any working group member can ask that something be added to the next meeting’s agenda by communicating to the Chair.
Prior to each meeting the Chair will share the agenda with members of the working group. Working group members can also add any items they like to the agenda at the beginning of each meeting. The Chair and the working group members cannot veto or remove items.
The working group may invite persons or representatives from related projects, stakeholders, or user communities to participate in any meeting in a non-voting capacity.
The Chair, or their delegate, is responsible for summarizing the discussion of each agenda item and sends the meeting notes to all working group members after the meeting.
## Decision Making Process
The working group follows a Consensus Seeking decision-making model.
When an agenda item under discussion has appeared to reach a consensus the Chair, or any working group member, will state the decision that is perceived to have been reached and ask, "Does anyone object?" as a final call for dissent from the consensus.
If an agenda item cannot reach a consensus, a working group member can call for either a closing vote or a vote to table the issue to the next meeting. The call for a vote must be seconded by a majority of the working group or else the discussion will continue. If a vote occurs, simple majority wins and the Chair does not have tie breaking capacity (i.e., the Chair’s vote does not hold more weight than any other member). In the event of a tie, discussion will continue until a majority vote or consensus is reached.
Note that changes to the working group membership require consensus. If there are any objections to adding or removing individual members, an effort must be made to resolve those objections. If consensus cannot be reached, then the discussed change to membership is not implemented.
## Asynchronous Communication and Collaboration
In addition to monthly meetings, the Lunar SDI working group maintains a public repository of working documents, meeting notes, and presentations. This folder is a mechanism for asynchronous collaboration between members and allows for collaboration on tasks pertaining to the management of this SDI (e.g., editing documents, developing standards, supporting data ingestion). All group members have access to this internal use folder. Email is also commonly used to communicate with the working group between meetings.

**DRAFT**
The Lunar Spatial Data Infrastructure (SDI) Working Group is a voluntary cooperation between planetary community members to evaluate existing spatial data and data standards for the moon and assess spatial data storage, acquisition, discovery, and use needs of the Lunar community. The Lunar SDI will be seeking endorsement by the NASA directed Mapping and Planetary Spatial Infrastructure Team (MAPSIT). The overarching goal of the Lunar SDI is to allow individuals that are not spatial data experts to use spatial data to the greatest extent possible, with the lowest possible overhead (Laura et al., 2018). This working group addresses spatial data complexities by defining policies and standards regarding data interoperability, data contribution, and the long-term maintenance for the benefit of all user communities. See the Lunar SDI Strategy Document for additional information.
The purpose of this governance document is to describe the organization of the Lunar SDI Working Group and the agreed upon policies for group norms, SDI data and license standards, membership in this working group, the working group organization, and decision-making procedures.

title: Recurring Agenda Topics
weight: 5
---
**DRAFT**
Subject matter expertise within the Lunar SDI Working Group is organized primarily around the following topics, which are closely related to the Lunar SDI objectives (see Appendix 1 below and the Lunar SDI Strategy Document). However, additional topics may be added to the agenda at any time. Smaller focus groups may meet separately or asynchronously, as needed, and the results of such discussions are presented to the entire working group at regular meetings.
### Foundational And Framework Data
This topic focuses on the definition of standards within the Lunar SDI for interoperability and remote data access as well as the definition of metadata standards to support discoverability, the prioritization of higher-order data product creation, and the definition of a semantic vocabulary or ontology to support more complex data discovery activities. This working group coordinates and manages a listing of available data within the Lunar SDI and solicits for data to be added to the SDI, the publishing of an initial set of standards including standardized vertical and horizontal datums (i.e., the coordinate system), accepted map projections, standardized data and metadata formats to support interoperability, and standards to ensure interoperability of Lunar SDI search APIs. Three foundational data themes include geodetic coordinate systems, elevation, and orthoimagery. Framework data are defined as spatially enabled data products that serve a smaller user group and in conjunction with foundational data support additional science and engineering goals (Laura et al., 2017).
### Applications and Tools
A primary objective of this working group is to engage tool developers to ensure support for data and standards included in the Lunar SDI and to build partnerships with such groups. This working group provides a venue for the discussion and possible promotion of new capabilities that leverage the SDI and supports the identification and prioritization of technical capability that could be developed to support user interaction with the SDI.
### Portals
Coordination between data providers and data custodians to ensure availability of data products is critical to realizing the full potential of the Lunar SDI. This working group is concerned with SDI data storage in the cloud, data access, and ensuring FAIR principles are upheld. This working group coordinates the maintenance of, in conjunction with the Lunar community, a living inventory of foundational and framework data products including quantitative (e.g., positional accuracy, resolution, data producer) and qualitative (e.g., fitness-for-use) metadata. It also enables the development of data discovery and access portals making use of Lunar SDI managed data and associated APIs.
### Website and Communication
This working group strives to engage our users and to respond to the needs of the Lunar community. To that end, this working group will maintain the Lunar SDI public websites, data catalog, and mechanisms for communication with user groups, stakeholders, and the general public. This working group also coordinates engagement with the user community, funding agencies, and NASA Advisory Groups to ensure the efforts of this body maximally align with targeted user community needs. Community feedback is synthesized, and responsive action items are also developed.

title: Working Group Organization
weight: 4
---
**DRAFT**
The Lunar SDI Working Group is the decision-making body of the SDI. The working group members collaboratively formulate the mission, vision, governance model, data and metadata standards, and strategic direction for the development and maintenance of the Lunar SDI. This working group approves work efforts required to meet the strategic goals of this group and provide guidance to support the implementation of those decisions. The working group also establishes and maintains relationships with NASA program managers, data providers, and community user groups and stakeholders, such as Lunar science and engineering communities, mission teams, software application and tool developers, media relation activities, public engagement and education groups, and members of the general public.
## Membership
This working group consists of voluntary working group members and topical sub-groups. There is one Chair, one Co-Chair, and an unlimited number of members.
Current Membership Includes:
Working group memberships are not time limited. There is no maximum size of the working group. The size is expected to vary to ensure adequate coverage of important areas of expertise, balanced with the ability to make decisions efficiently. The working group must have at least five members. Chairs and Co-Chair serve one-year terms from October 1 to September 30. During the August meeting, individuals self-nominate to serve as Co-Chair and the working group determines the new Co-Chair by majority vote. After the one-year term, the Co-Chair then serves as the working group Chair. A change of the Chair or Co-Chair can be made mid-year by the same process described above and as deemed necessary by consensus of the working group members. Mid-year changes are expected to be rare.
There is no specific set of requirements or qualifications for working group membership. The working group may add additional members by consensus. If there are any objections to adding any individual member, an attempt should be made to resolve those objections following the Consensus Seeking Process (see section 5.2). A working group member may be removed from the group by voluntary resignation or by consensus of all other members.
Changes to working group membership should be posted in the agenda and may be suggested as any other agenda item. If an addition or removal is proposed during a meeting, and the full working group is not in attendance to participate, then the addition or removal is added to the agenda for the subsequent meeting. This policy is to ensure that all members are given the opportunity to participate in all membership decisions.
In the case where an individual working group member - within any twelve-month period - attends fewer than 25% of the regularly scheduled meetings, does not participate in working group discussions, and does not participate in working group votes, the member shall be automatically removed from the working group. The member may be invited to continue attending working group meetings as an observer.
To express interest in serving on the Lunar SDI working group, please email the current Chair (see section 4.1).

## Performance Indicators
Several performance indicators will be measured over the time period from 2022 to 2025 to gauge the effectiveness of the implementation of the Lunar SDI Strategic Plan, as well as the effectiveness of the Lunar SDI itself. These efforts will be measured, assessed, and tracked annually over the 2022 to 2025 timeframe with regular reports publicly available.
Performance indicators will include qualitative or quantitative metrics on:
- Relevance of Lunar SDI reference and thematic data to users
- · The use of the Lunar SDI Geoportal, web services, and metadata
- User satisfaction of reference and thematic data and services
- Known applications based on the Lunar SDI and their relevance
- · Lunar SDI policies and standards influence on the development of other NASA SDIs and other relevant management policies
## Objectives and Anticipated Outcomes
This plan contains information regarding how the strategic objectives will be implemented within the Lunar SDI including the anticipated outcomes, approach, and a table of actions including a general timeline.
### Objective 1
Publish and steward the policy infrastructure necessary to maintain this SDI, including a charter, governance documentation, memorandums of understanding to support data release and sharing agreements, and a roadmap of future development.
#### Anticipated Outcomes
Publishing and maintaining a policy infrastructure is one of the primary tenants of a Spatial Data Infrastructure (e.g., Laura et al., 2018; Rajabifard et al., 2002), and facilitates communication within the community, coordination between stakeholders, communicates expectations both of the SDI and from participating groups, and establishes efforts for the long-term maintenance of this infrastructure.
#### Approach
The primary approach includes writing documentation that describes 1) the Lunar SDI charter, 2) governance policy documentation; 3) strategic direction and a 4-year roadmap; and 4) user and contributor agreements. These documents will be drafted by Lunar SDI working group members and reviewed collectively. We will seek group consensus regarding all governance and strategy decisions. These documents will also be posted on a publicly available website so that members of the Lunar community can also comment and provide feedback.
#### Actions
| | Action | Status |
|--|--------|----------|
|1.1 |Write and publish the Lunar SDI Charter | Current effort. |
|1.2 |Write and publish the governance documentation | Current effort. |
|1.3 |Write and publish the strategic direction and 4-year roadmap (this document) | Current effort.|
|1.4 |Write and publish the memorandum of understanding |Future effort. |
### Objective 2
Engage with the user community, funding agencies, and NASA Advisory Groups to ensure the efforts of this body maximally align with targeted user community needs.
#### Anticipated Outcomes
Engaging a broad range of Lunar data users will help to ensure that our efforts strategically align with the needs of the community and will also inform this community of our efforts. In this way, potential users can learn of available data and future planned additions, while also providing opportunities to stay in step with the evolving needs of data users. The feedback we receive from users will help to inform current and future efforts and SDI direction.
#### Approach
We will initially engage high-level stakeholders, including NASA, MAPSIT, and LEAG, to ensure that this working group is addressing a widely recognized need in the community. We will also engage mission teams to communicate the efforts of this group, seek collaborative engagement, and ensure that our efforts are supportive and not redundant to mission team efforts. We will also engage the planetary science community at annual meetings to obtain feedback on our efforts and collaborate with other interested groups. This approach helps us to initially understand the needs of scientists, engineers, mission teams, and software and tool developers. We will then build on this understanding to inform future work to serve the larger community of users and stakeholders, which in addition to the above groups include (but are not limited to) media relation activities, public engagement and education groups, and members of the general public. By engaging the Lunar data community through many different avenues, we aim to intersect and meet the data use needs of the broadest group possible.
#### Actions
| | Action | Status |
|--|--------|----------|
|2.1 |Engage NASA to ensure this effort is supportive of strategic direction and community needs and provide regular updates. |Ongoing. This effort directly addresses needs expressed in the Planetary Data Ecosystem IRB Findings; we provide annual updates to NASA Program Managers.|
|2.2 |Engage the Mapping and Planetary Spatial Infrastructure Team (MAPSIT) to communicate the efforts of this group. |Current effort. |
|2.3 |Engage the Lunar Exploration Analysis Group (LEAG) to communicate the efforts of this group. | Current effort. |
|2.4 |Engage relevant mission teams to communicate the efforts of this group and work to establish a cooperative relationship that supports community needs. | Future effort. |
|2.5 |Present the efforts of this group at relevant community meetings, such as the Lunar and Planetary Science Conference (LPSC) and the American Astronomical Society Division of Planetary Science (DPS) meetings. |Future effort. |
|2.6 |Engage tool developers to communicate the efforts of this group. |Future effort|
### Objective 3
Publish an initial set of standards that will define this SDI including standardized vertical and horizontal datums (i.e, the coordinate system), accepted map projections, interoperable data formats, and metadata formats.
#### Anticipated Outcomes
A defined set of standards for the Lunar SDI will foster consistency in projections, data formats, and descriptive documentation in metadata. This consistency will lead to greater interoperability between components in this SDI and will result in data products that are immediately analysis ready by removing the need for additional data processing or reprojection.
#### Approach
Standards will be defined by considering current standards in use for the moon and those most often used by the Lunar community. We will consider existing IAU standards, and we seek to be consistent with standards defined by authoritative sources. When multiple or conflicting standards are in common use, we will determine the standard we believe best meets the needs of our user community through discussion within the Lunar SDI Working Group. We will publish these standards on a public website.
#### Actions
| | Action | Status |
|--|--------|----------|
|3.1 |Inventory existing projection, data format, metadata, and other standards currently in use by the Europa community and including the Europa Clipper mission team. |Future effort.|
|3.2 |Identify IAU-endorsed standards relevant to the moon. |Future effort.|
|3.3 |Define a set of standards to be used within this SDI to maximize consistency and interoperability. |Future effort.|
|3.4 |Publish standards on a public website. |Future effort.|
### Objective 4
Maintain, in conjunction with the Lunar community, a living inventory of foundational and framework data products including quantitative (e.g., positional accuracy, resolution, data producer) and qualitative (e.g., fitness-for-use) metadata. This includes setting a standard for metadata to be reported for all data products managed under the Lunar SDI organization.
#### Anticipated Outcomes
Maintaining a living inventory of foundational and framework data products will benefit the Lunar data community by simplifying the search and discovery process. Collecting these data into a single clearinghouse, with descriptive and standards compliant metadata, allows the community to know what data products exist, the accuracy of those products, and whether they meet the needs of that use case. In addition, such an inventory allows NASA, mission teams, and data producers to identify gaps in knowledge that could be filled through future efforts.
#### Approach
Our primary approach is to build on the efforts of Laura and Beyer (2021) and findings from the Lunar Critical Data Products Specific Action Team (2021) use this information as an initial assessment of the publicly available foundational and framework data products for the moon. We will also engage data producers to determine interest in contributing to this SDI and determine the process to contribute additional data products. As additional data products are published in the literature or through community data portals/catalogs (e.g., the Planetary Data System), we will include them in our inventory, link to the publicly available products, and assess including them in this SDI.
#### Actions
| | Action | Status |
|--|--------|----------|
|4.1 | Inventory the publicly available foundational and framework data products for the moon.|Completed in 2022. Laura and Beyer (2021) and the Lunar Critical Data Products SAT (2021) provide an initial assessment of such products.|
|4.2 |Engage Lunar data producers directly to collaborate and support including products in this SDI. | Future effort. |
|4.3 |Maintain knowledge of new data products published by the community for potential inclusion in our inventory. |Ongoing|
|4.4 |Develop a process for contributing data to this SDI, including a Memorandum of Understanding that supports sharing agreements between stakeholders (related to action 1.4). | Future effort.|
### Objective 5
Provide a mechanism to bring users together, such as data creators (who make the data products), custodians (who manage the data products lifecycle), and data integrators (who provide the data to end users) to create an interconnected user group.
#### Anticipated Outcomes
The Lunar SDI benefits from maximizing the availability of interoperable Lunar data to support the broadest possible user community. As a communication tool, the Lunar SDI helps connect data creators with data stewards who ensure that generated data are broadly available. We anticipate this objective resulting in the identification of institutions that wish to act as data stewards and to whom data creators can submit data for inclusion in the Lunar SDI.
#### Approach
Our primary approach is to first lay the groundwork to incorporate data contributions from data creators in a transparent manner where the expectations of the data creators, custodians, and data integrators are clearly identified and documented. Planned initial steps include developing clear documentation of standards and formats that are expected for all data products in the Lunar SDI, ensuring such documentation is publicly available, and engaging Lunar data producers. Once this initial foundation is established, we will identify institutions that are willing and able to serve as data stewards and engage the broader data community in these efforts.
### Actions
| | Action | Status |
|--|--------|----------|
|5.1 | Engage Lunar data producers and gain experience incorporating data from multiple institutions (related to action 4.2) | Future effort. |
|5.2 |Develop and publish Lunar SDI standards (related to action 3.4). | Future effort. |
|5.3 |Identify institutions that can and will serve as data stewards. | Future effort. |
|5.4 |Engage other data creators and stewards to identify one or more additional participants. |Future effort.|
|5.5 |Engage tool and service providers to build partnerships using the available data service(s) (related to Objective 8). |Future effort.|
### Objective 6
Support (through policies and standards) the development of data discovery and access portals making use of Lunar SDI managed data and associated Application Programming Interfaces (APIs).
#### Anticipated Outcomes
Supporting the development of data discovery and data access by the broadest possible user community is a fundamental goal of the Lunar SDI. Through policies and standards, we will provide a framework by which data can be organized, identified, searchable, and used while minimizing the need for post-processing or reprojection of data. We anticipate that this focus on standardization and data discovery will enable Lunar data to be more easily discoverable in a format that is analysis ready, lead to a reduction in redundant data processing efforts across the Lunar community and potentially allow for current data processing resources to be used for science and engineering investigations.
#### Approach
Our approach to supporting data discovery and access is to develop policies and standards that are consistent with community leading practices. We will identify and implement practices that have demonstrated success in terrestrial and other communities and are relevant to the Lunar community. We will also engage the Lunar community user groups to educate potential users on the availability of this SDI and solicit feedback on its usability. Finally, we will enable metrics on our websites and data portals to allow us to measure and evaluate how the community is interacting with our services and what data products and services are most impactful. These metrics will inform future efforts to modify our approaches and better support the Lunar data community.
### Actions
| | Action | Status |
|--|--------|----------|
|6.1 |Research community leading practices for data policies, standards, and technologies that enable discovery.| Future effort. |
|6.2 |Identify and implement practices that are applicable to the Lunar community and practical to implement. | Future effort. |
|6.3 |Engage Lunar community user groups to educate potential users on the availability of this SDI and seek community feedback.| Future effort. |
|6.4 |Enable metrics to measure the use of the Geoportal, APIs, and the download of data.| Future effort. |
### Objective 7
Ensure the public release of all Lunar SDI managed data products and APIs.
#### Anticipated Outcomes
Publicly releasing all data products and APIs managed under the Lunar SDI ensures that these resources are available to the widest audience possible and seeks to democratize the availability of these data and infrastructure. We aim to publicly release all data and APIs in a manner that is discoverable, accessible, and usable (Laura et al., 2018), and that follows leading FAIR practices (Wilkinson et al., 2016).
#### Approach
The Lunar SDI working group will make data available under both FAIR data principles and the spatial standards defined by the Lunar SDI working group, and to be compliant with NASA data release policies. Our approach to data product and API release follows the guidelines described in the NASA Scientific Information policy for the Science Mission Directorate (SPD-41). Specifically, data formats will be machine readable to allow for automated processing and will include robust, standards-compliant metadata. All data, APIs, and software will be released under an open license, and will be indexed as part of the appropriate NASA catalog (i.e., either data or software). Our repository will also adhere to standards for accessibility of all electronic and information technology for people with disabilities and with a principle of non-discriminatory data access so that all users will be treated equally.
### Actions
| | Action | Status |
|--|--------|----------|
|7.1 |Define the appropriate license for data and software release and document in the Lunar SDI Governance Document. |Future effort.|
|7.2 |Establish standards compliant data and metadata formats for this SDI that fulfill SPD-41 requirements (related to objective 3) and document in the Lunar SDI Governance Document.| Future effort.|
|7.3 |Determine industry standards for repository accessibility and develop actions to ensure these standards are met or exceeded. |Ongoing|
|7.4 |Apply for CoreTrustSeal Certification to become a trusted data repository.| Future effort. |
### Objective 8
Engage with tool developers to ensure support for data and standards included in the Lunar SDI.
### Anticipated Outcomes
We seek to provide a catalog of data and derived data products in a well-documented and standardized format that will benefit many user communities. By engaging with tool and data portal developers, we will better understand the needs of this community and be positioned to collaborate with these groups. We seek to minimize the need to regenerate or reprocess existing data, thereby minimizing redundant efforts within the Lunar community. This engagement will help us to provide data in a manner where tool and data portal developers could access the data within the SDI with minimal subsequent processing needed, rather than these providers regenerating or reprocessing data themselves.
### Approach
We will identify groups developing tools or data portals targeted for use by the Lunar community and initiate communication with these groups. We will engage in informal collaborations with interested teams, seeking to develop mutually beneficial partnerships. Our collaboration focus will be educating others about the availability of data, supporting others in the use of Lunar SDI-provided services, identifying points of friction for using the Lunar SDI, and using this feedback to help develop future efforts.
### Actions
| | Action | Status |
|--|--------|----------|
| 8.1 |Action
Identify groups developing tools or data portals targeted for use by the Lunar community. |Future effort|
| 8.2 |Initiate communication with the above defined groups. |Future effort|

## Strategic Plan Overview and Executive Summary
This Lunar Spatial Data Infrastructure (SDI) Strategic Plan contains a high-level overview of the background, guiding principles, and philosophy of the Lunar SDI and describes the primary strategic objectives from 2022 to 2025. This document explains where and how resources could be best spent to develop and implement the Lunar SDI to support a coordinated and strategic effort to provide analysis ready data to Lunar scientists and engineers, mission teams, the planetary community, and the general public. This document also relates each of the strategic objectives listed below to actions that support accomplishing the objectives, and their anticipated outcomes, to ensure agreement on responsibilities, coherence, and timing for deliverables.
## Background
The Lunar Spatial Data Infrastructure working group is a voluntary cooperation between planetary community members to evaluate existing spatial data and data standards for the moon and assess spatial data storage, acquisition, discovery, and use needs of the Lunar community. The Lunar SDI is endorsed by the NASA-directed Mapping and Planetary Spatial Infrastructure Team (MAPSIT). A spatial data infrastructure (SDI) is the enabling collection of spatial data users, data interoperability agreements, policies and standards, data access mechanisms, and the spatial data themselves (Rajabifard et al., 2002). The overarching goal of the Lunar SDI is to allow individuals that are not spatial data experts to use spatial data to the greatest extent possible, with the lowest possible overhead (Laura et al., 2018). This working group will address complexities by defining policies and standards that will be applicable to this Lunar SDI regarding data interoperability, data contribution, and the long-term maintenance for the benefit of all user communities.
The policy decisions made for the Lunar SDI consider the diverse groups interested in accessing high-quality and processed data, and include the Lunar science and engineering communities, mission team needs for strategic planning and targeting observations, software application and tool developers, media relation activities, public engagement and education groups, and members of the general public. Understanding this diversity of long-term stakeholders, the Lunar SDI strategy will first focus on the needs of scientists, engineers, mission teams, and software and tool developers, and then build on this understanding to inform future work to serve the larger community of users and stakeholders. The Lunar SDI aims to improve the infrastructure for public access to and distribution of geospatial planetary data and help ensure that it is Findable, Accessible, Interoperable, and Reusable (FAIR; Wilkinson et al., 2016). It also aims to be a clearinghouse where data in a standardized format can be shared, duplication reduced, and community needs prioritized. In the context of the Lunar SDI, a data clearinghouse is a distributed system of data servers and services which have standardized metadata to facilitate data interoperability. The clearinghouse is a single access location that uses web standards to allow data discoverability. This working group will also help to ensure that valuable information is preserved for posterity in a way that is discoverable, has a high degree of usability, and can foster innovation and experimentation even while missions are actively collecting data (c.f. Planetary Data Ecosystem IRB Report, 2021).
An SDI is an aspect of a Planetary Data Ecosystem (PDE), is complementary to the Planetary Data System (PDS) and serves a distinct need in the planetary community. An SDI is not an archive and therefore does not in any way replace the critical need for the PDS to ensure that NASA-collected data are preserved in perpetuity. Instead, the Lunar SDI working group aims to provide additional functionality, access, and services for Lunar data that are built upon the important foundation the PDS provides (Laura et al., 2022), such as establishing policies, standards, and agreement between data providers that are focused on the needs of a specific community – in this case, those using spatial data collected of the moon. The Lunar SDI is a component of the PDE that is currently focusing on analysis ready data and metadata availability and services (Laura et al., 2022).
## Europa PSDI Vision and Mission
**Vision:** The Lunar Spatial Data Infrastructure will facilitate access to spatial information in support of mission planning, scientific investigation, and public outreach efforts
**Mission:** The Lunar Spatial Data Infrastructure mission is to promote cooperation and development of a Spatial Data Infrastructure that enables discovery, access, interoperability and sharing of Lunar spatial data, while pursuing best data management practices (modeled after the Arctic SDI).
# Guiding Principals
The following guiding principles are used to assess proposed activities and priorities when formulating and communicating the strategy of the Lunar SDI:
The Lunar Spatial Data Infrastructure:
· Is a voluntary cooperation between planetary community members
· Is focused principally on the relevant Europa data users, data providers, and stakeholders
· Reflects user and stakeholder needs to enable interoperability and reusability via standardization
· Remains focused on its strategic plan while developing infrastructure and services
· Leverages existing NASA SDI and Planetary Data Ecosystem (PDE) investments
