What is the correct way to project an existing shapefile that has a .prj file associated with it containing the following information into any other coordinate system for e.g. web mercator?
GEOGCS["HRAP_Sphere",DATUM["<custom>",SPHEROID["<custom>",6371200.0,0.0]],PRIMEM["Greenwich",0.0],UNIT["Degree",0.0174532925199433]]
A sample shapefile is attached.
