System locator

Got an X, Y but don't know its system? TopoTeam tests the common systems and places the point on the map.

Point coordinates

Enter X and Y (comma or dot accepted), or pick the point directly on the map.

X (easting) or longitude

Y (northing) or latitude

How to find coordinate systems from a map?

How does the Map Coordinate Locator work?

Enter your local X and Y coordinates. The locator uses reverse projection algorithms to test thousands of EPSG systems simultaneously. It identifies which projection correctly places your point on the satellite map.

Can I get X,Y coordinates by clicking on the map?

Yes! Activate the Map Picker mode, click anywhere on the interactive satellite map, and our tool will automatically compute and display the local X and Y coordinates for all compatible geodetic projection systems in your region.
