NOAA provides QPF data on rainfall in the form of shapefiles. The shapefiles include .prj files with information on the coordinate system used:
I was under the impression that NOAA data used WGS84, but it looks like this is not the case and it uses GCS_Sphere_EMEP. Am I misinterpreting the .prj file?
I am using this shapefile alongside route data from Google Maps which uses WGS84. I am not familiar with the Sphere_EMEP coordinate projection. Should I simply reproject the shapefile to use a WGS84 projection?
