Cloud Native GIS Tools

Archive complete HEC projects and turn their geometry and results into open, analysis-ready cloud-native formats. Choose the library that matches your modeling system.

  • ras2cng

    Export complete HEC-RAS projects — geometry, terrain, plans, and simulation results — to GeoParquet, PMTiles, DuckDB, PostGIS, and web-map-ready datasets.

  • hms2cng

    Export complete HEC-HMS projects — basin geometry, meteorology, control data, and simulation results — to GeoParquet, PMTiles, DuckDB, and PostGIS.
