Assign CRS to Geospatial File
Set the coordinate reference system metadata on a file that is missing CRS info. Supports both vector and raster formats.

Assigning a CRS writes projection metadata to a file without changing any coordinate values — use this when you know the correct CRS but the file is missing its .prj file, was exported without CRS metadata, or is being rejected by GIS software due to an unknown coordinate system.
