Hi,
How can I import NASA SRTM DEM data, stored in a file format called
hgt, into VTK-5.3.x?
See r.in.srtm. Then export to whatever VTK reads with r.out.gdal.

Hi,
I have imported some tiles of 1 arcsecond SRTM data into GRASS 6.3 using
r.in.srtm into a lat-long region. Whenever I import them to a UTM
region, res=30, I get aliasing problems. This results in a grid of
lines of jumps in elevation running through my data.

Hi,
I need some help as the results that I get at the moment are not what I
expect.
Task:
I want to transfer some irregular spaced points (height values) to a
regular spaced dataset by interpolation.
What I tried:
v.in.ascii to import the points (looks good from display)
v.to.rast

r.resamp.interp to interpolate the gaps
Maybe your approach is correct, but I've never used this command for
interpolation.
If you wish, try this:
v.in.ascii (same as before)
g.region -p -a

Hi,
I have a 16244x12706 GeoTIFF file (600dpi scan) which is made up of 7
