[GRASSLIST:1026] srtm

[Ian Macmillan]

Hi all, you all have been very helpful in the past, so I am hoping you keep your
patience with me.

I have downloaded some SRTM data from the USGS web site, and it so happens that
my data is near the coast.  My trouble is that SRTM actually records some
anomalous data out in the oceans.  I have bathymetry data that i would like to
view along with topography, but the ocean data is a bit difficult to get rid of
from the SRTM.  My thought is that I might be able to take the coast lines
generated from GMT, import those into GRASS, and then somehow mask out all data
from the SRTM that lies outside of those coastlines.

Does anyone have any experience with this?  Is there another way that I am
ignoring?

I thought I saw an email about this recently, but I couldn't find it in the
archives.

thanks, Ian
