Hello GRASS Users,
I cannot seem to find a modern method to import DTED into GRASS. I've RTFM but
cannot determine what I'm doing wrong.
I am attempting to bring in DTED Level 1 data from a file on CDROM (not a
tape). I thought I was successful using r.in.gdal, but the raster displayed
looked nothing like the terrain I'm working in. It looks more like the side of
a zebra - irregularly striped.
I have looked at the commands r.in.ll, r.in.dted, m.dted.examine,
m.dted.extract, m.rot90, etc.
What basic concept am I missing?
I'm using GRASS v5.0b11, Linux 2.2.13.
TIA
Gerald

r.in.gdal doesn't do the colors at the moment. Try running r.colors (use
"grey" or similar). For best effect, you'll want some kind of
hillshading or some such (NVIZ can do nicely...).

Having just imported my rtf files using n.in.ntf2. I have another question
(thanks to Eric Miller previously by the way).
I have been reviewing the literature on r.patch. My confusion lies in the
suggestion that after using r.patch for raster maps we should use the
programme v.mkgrids to "make adjacent maps align neatly together".
As I later wish to use the raster program r.cva this seems unwise as
v.mkgrids converts the patched map to a vector map.
Does anyone have any ideas?
best wishes,
Gail.
