isLonLat.Rd
Test whether a Raster* or other object has a longitude/latitude coordinate reference system (CRS) by inspecting the PROJ.4 coordinate reference system description. couldBeLonLat
also returns TRUE
if the CRS is NA
but the x coordinates are within -365 and 365 and the y coordinates are within -90.1 and 90.1.
