Hi,
has anyone qot the windows version to work?
I'm new to GRASS and I'm not sure if I'm doing this the right way.
I'm trying to create contour lines from a DTED file (name=f2227)
g.region rast=f2227 -p
d.erase
d.rast f2227
Which windows version are you using ? Cygwin or native ? If you can run
d.mon x0, then this must be Cygwin.
r.contour in=f2227 out=elev_c_10m step=10 --o
the r.contour program starts but nothing happends!!
works perfectly in native wingrass
I'm also trying to triangulate the dted file:
First I tried to create vector points from the dted file
r.to.vect input=f2227 output=point1 feature=point -s
the program starts but nothing happends!!
idem
Then I succeded to create the point file in Qgis GRASS module
after that I draped the pointfile with the elevation file (2D to 3D) in
Qgis.
It created a new point (point3d) file but I can't se if it is in 3D.
How did you create this file ?
but the:
v.delaunay input=point3d output=deltriang
I don't know what point3d is, and am not a triangulation expert, but I
don't see how the output of r.to.vect is useful for triangulation,
unless you change resolution before r.to.vect...
Craches after a while in Qgis
Works in native wingrass.
in WinGRASS
the delaunay function completes (without any succeed- or error message).
How do you launch it ?
But when I'm trying to view the layer, I'm getting the following
message:
"coor files of vector deltriang is larger than it should be (9287051
bytes excess)"
and
"Cannot display areas, topology not availible"
Try running v.build on the file.
