hello sir
I have a LANDSAT image imported in my mapset using r.in.gdal. I used
r.composite to combine the rgb files. After all these, now if I wants to get
the pixel value on click of a mouse on the raster map. Is it possible for me
to somehow get the pixel value (that is red, blue and green

of the DEM after exagerating it.Now I am looking forward to drape an aerial
image of the same area on the DEM that I have got. In order to do this I
loaded the DEM map and then draped the imported aerial map (imported using
r.in.gdal, but that single jpeg image(satimage.jpg) got imported into 3
Hello sir
Thanks for the link. I finally got the coloured aerial image draped on the
DEM map and which can be viewed in nviz. Since the aerial image was getting
imported in an rgb files (3 different files) I first needed to combine them
into one raster map, which could be done using
hello sir,
thanks for the link. I have tried it out and it works with v.surf.rst. But when
I use r.surf.contour it takes a very very long time and it never ends. I would
be thankful if you could suggest me something regarding the resolution(grid
resolution 2d in g.region modules resolution

hey Achim
Thanks for replying.I tried many things like v.surf.rst, r.surf.contour etc
but still I could'nt get the desired output, sometimes it runs for a
long-long time which never ends and sometimes after the resolution being
changed it gives weird output and which cannot be viewed in NVIZ it
hey,
I think the output you got is correct. But when i try to change the
resolution (eg: 0:00:01) in the g.region resolution tab(GRID resolution 2D
both north-south and east-west), it gives an error saying :ERROR: Invalid
input res=0:00:01. Am i doing something wrong???. And one more thing is
Hi Nikhil,
And one more thing is
that how have you converted the height to integer please give me
details of
this too. I am really very thankful for your time and effort.
There are many ways. For example like Micha said:

I'm including a mapset bombay with the contour vecto, the
