Understanding CSV Coordinate Detector
Coordinate systems, order and units
Detect likely latitude, longitude, easting, northing, WKT, and GeoJSON columns in a CSV before conversion.
CSV Coordinate Detector 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
Detection is advisory. Confirm ambiguous x/y columns and their CRS before conversion.
To verify CSV Coordinate Detector, 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.
