Hi,
I have two questions, first a specific one, secondly a more general one.
1) I have some aerial photos that I want to mosaic. I am able to do
this with r.patch. However, the photos only cover about half of the
region. In the remainder of the region, I would like to show a shaded
relief map as a background to give context to the photos. When I
include the shaded relief map in the list to patch, it comes out as
varying shades of red. My question is therefore, what do I have to do
to the shaded relief map to turn it into an 'rgb image' that I can
include in r.patch.
2) More generally, what is the best way of converting a good-looking
map into a georeferenced image e.g. by converting the elevation data
into rgb pixel colour data. Currently I would use d.out.file then
gdal_translate, but that is dependent on the screen resolution.
Cheers
John
