EPSG code

#1

I have the following projection file:


GEOGCS["GCS_North_American_1983_CSRS",DATUM["D_North_American_1983_CSRS",SPHEROID["GRS_1980",6378137.0,298.257222101]],PRIMEM["Greenwich",0.0],UNIT["Degree",0.0174532925199433]]


I need to know what the EPSG code is for this so that I can properly project it to Google Maps Overlay.

I am not sure there is an EPSG for this projection, so just use the projection string for Proj4:


"+proj=longlat +ellps=GRS80 +no_defs"


See Spatial Reference site: spatialreference.org/ref/sr-org/6706/



 Proj4Projection proj4 = new Proj4Projection();
 proj4.InternalProjectionParametersString = "+proj=longlat +ellps=GRS80 +no_defs";
 proj4.ExternalProjectionParametersString = Proj4Projection.GetGoogleMapParametersString();
