hecras-export-cloud-native

Export HEC-RAS geometry and simulation results to cloud-native formats: GeoParquet, PMTiles (vector and raster), and PostGIS. Uses ras2cng as a CLI wrapper over ras-commander parsers. Use when exporting HEC-RAS mesh geometry to GeoParquet, publishing results as PMTiles for web maps, querying HEC-RAS outputs with DuckDB SQL, syncing flood results to PostGIS, converting HEC-RAS to cloud-native geospatial formats, or generating vector tiles from simulation outputs. Keywords: GeoParquet, PMTiles, DuckDB, PostGIS, cloud-native, vector tiles, geometry export, mesh cells, cross sections, ras2cng.
