Recommended Formats Statement

Most complete data (all layers, appendices), even if proprietary, with a preference for preserving the native format and projection of the data

Vector formats compatible with widely adopted GIS including,

• Shapefile, which is comprised of at least a SHP, SHX, and DBF file and optionally a PRJ (highly recommended), XML (highly recommended), SBN, and/or SBX.

• GeoJSON (may have scalability issues)
• KML

2. Automated private download URLs with any necessary API keys or credentials
3. Hard drives

• For metadata information see Federal Geographic Data Committee (FGDC) and 191xx ISO standards
• To the extent allowed by the underlying format, include available information about how the data was created, collected and any post-processing which has been applied

Project and layer files (.mxd, .qgs, .lry) may be acquired with deposits of content data to assist in reviewing materials during deposit process

Files must contain no measures (such as digital rights management or encryption) that control access to or prevent use of the digital work.
