[Shake-dev] Error with Vs30 file

[Bruce Worden]

Hi Ophélie,

The problem seems to be the the Global Vs30 Server provides GMT grd files in pixel node registration and ShakeMap works in gridline node registration. You can fix your Vs30 file by doing something like:

	grdsample Southern_Europe.grd -Gnew_file_name.grd -T

You then configure grind.conf to look at "new_file_name.grd" and it should work.
