[gradsusr] Using geotiffs in Grads`

[Nick HEATH]

Hi everyone,

I am working with oil spill data, and I need a way to display the "oil" in my model.  I have geotiffs of the oil locations and I was wondering if there is any way to read those in.  I also have the locations in .gif files.  If that is not possible, does anyone have any good ideas of how I could make a "blob" of oil that I could apply equations to (such as a wind drift to watch how it moved through time)?

Here is the config of the Grads I'm using:

Config: v2.0.a8 little-endian readline printim grib2 netcdf hdf4-sds hdf5 opendap-grids,stn geotiff shapefile
