Shapefile Reprojector
Read a zipped Shapefile and reproject it to an explicit target CRS in-browser, producing GeoJSON rather than a new Shapefile.
Input
Leave Source CRS blank to use the archive projection metadata. A missing .prj requires an explicit source CRS. This tool does not write Shapefiles.

Understanding Shapefile Reprojector
Coordinate systems, order and units
Read a zipped Shapefile and reproject it to an explicit target CRS in-browser, producing GeoJSON rather than a new Shapefile.
Shapefile Reprojector depends on knowing how coordinates are expressed. Geographic coordinates commonly use WGS84 longitude and latitude, while projected systems use linear units and a defined datum and projection.
How to verify the coordinates
Leave Source CRS blank to use the archive projection metadata. A missing .prj requires an explicit source CRS. This tool does not write Shapefiles.
To verify Shapefile Reprojector, spot-check a known place, confirm axis order and verify the expected unit and CRS. A numerically valid coordinate can still be geographically wrong when those assumptions are incorrect.
