This question already has an answer here:
I am overlaying some WGS84 (EPSG:4326) coordinates over a few DEM rasters with EPSG:102710 (NAD_1983_STATEPLANE_NEW_HAMPSHIRE_FIPS_2800_FEET)
When they are these two different layer CRS the coordinates overlay perfectly where they are supposed to be, however, if I change the coordinates to have the same EPSG as the DEM rasters, then the coordinates are way off. What is the explanation for this?
The rasters were from this site: http://www.granit.unh.edu/data/search. "Digital Elevation Model - Quad 54" for example.
Unfortunately, I cannot provide the coordinates.
