Importing GIS data
Imported data becomes a layer: styleable on the map, queryable in SQL, and usable as a snapping target when you draw a network.
Supported formats
Section titled “Supported formats”| Kind | Formats |
|---|---|
| Vector | GeoJSON, GeoPackage, Shapefile (zipped), CSV with coordinates |
| Raster | Cloud-optimised GeoTIFF (COG) |
How it works
Section titled “How it works”Vector files are read in the browser and converted to a table you can query. Nothing is sent anywhere — the parse happens locally, which is why large files are limited by your machine’s memory rather than an upload quota.
Coordinate systems
Section titled “Coordinate systems”Data is reprojected on import. If a layer lands in the wrong place, the usual cause is a missing or incorrect projection definition in the source file rather than the import itself.
