### Accuracy Descriptions
- Accuracy should be described using the [ISO 19157:2013 standard](https://wiki.icaci.org/index.php?title=ISO_19157:2013_Geographic_information_-_Data_quality). 

### File Formats
- Data will have an FGDC compliant XML metadata file. This file is to be as compliant as possible and should use the planetary domain extension.
- Data will have a Spatio-Temporal Asset Catalog (STAC) metadata JSON file.
- Data should have a provenance file that minimally describes the creation of the data. When possible, the provenance file will support complete reproduction of a derived data product by replicating commands provided to processing tools.
