About

Good interstate data usually ends up trapped inside whichever app extracted it, named for that app's needs and versioned on that app's schedule. OpenInterstate keeps the data layer public and independent. The published contract defines the data, and downstream tools adapt to it rather than the other way around.

Principles

• Use neutral, boring public names
• Publish reproducible, checksummed releases
• Keep lineage and attribution explicit
• Optimize for developers and GIS users first
