I have some coordinates from Switzerland
X_KOORD | Y_KOORD |
488200 | 113800 |
488400 | 112100 |
487600 | 114100 |
488500 | 112100 |
But they didnt give me a coordinate system. Doing some research I found they use a grid in metters but not sure what is the one they use.
What is the most common grid used in europe?
It is probably EPSG:21781, CH1903 / LV03. The coordinates you posted are southwest of Geneva. There are 2 other possible Swiss projected coordinate systems--but those coordinates don't fall within the country if you use either of the other projected coordinate systems.
