Hi,
Over the last couple of years I have noticed a very strange raster
corruption (?) issues when using r.series, and now more recently,
t.rast.series. Typically, I'll generate a large number of maps with
r.sun or t.rast.mapcalc and then aggregate the series with r.series or
t.rast.series. About 5
Supposing that you had the road network and USGS NED data loaded into
GRASS, you could use the v.drape command:
http://grass.itc.it/grass65/manuals/html65_user/v.drape.html
You may be able to automate this, by looping over counties,
downloading the minimum NED required, running v.drape, and then

Not to rain on anyone's parade... but this type of operation tends to scale

Hi,
There is also a tool called Starspan than uses GDAL and GEOS to do
arbitrary zonal stats.

ermediate file (usually a shapefile).
Any ideas on what could be causing this problem? Fixing it would solve several
important issues. If need be I will file a new ticket on the topic.
Relevent tickets?

Hi Vishal,
Are you positive that you are invoking the latest gdal tools and libraries? I
would remove any that you have installed via package manager (aptitude,
etc.), and then run"
gdal-config --version
