Hi.

I'm trying to use geo hms for a distribuited model based on radar rainfall.
I'm trying to use the ModClark processing but I have a problem:
Select ModClark processing then select SHG method or HRAP method and during
this step
Appear an error message:

SOURCE PROJECTION IDENTIFICATION:
The spheroid GRS1880 is not supported in arcview!

Could anyone please help me?
