Hello everybody,
Is somebody knows how extracting coordinates systems (latitudes and longitudes) from a raster?
In the attribute table of the raster, I don't have the lat/long (just OID, value and count) but I need to extract lat/long to modify my layer for an other project.
So I've tried the "extraction by points" by Spatial Analyst but it doesn't work because the lat/long don't appear.
Thanks for your help,
