Hi
I would like to combine potentially 100s of 2d rasters into one 3d raster.
Instead of using r.to.rast3 which could take a long time to prepare the
setting, is there a way to export the raster as point files, and combine
them using for example MsAccess, and then reimporting them into one 3d
raster file?
Alternatively, is it possible to combine several 3d raster into one 3d
raster? i could combine ten 2d rasters into one and then combine the
multiple 3d rasters into one larger one.
If Stefan's suggestion does not help, and if each 2D raster is of one
constant height, you could try a combination of r.out.xyz and r3.in.xyz
with some magic in between to include a z. Here's an uncomplete and
untested algorithm for Linux in
height = 0
for each raster:
height = height + step
r.out.xyz raster out=- | awk -v var=$height -F'|' '{print
$1,$2,var,$3}' >> combined_raster
then
r3.in;xyz combined_raster
