Hi to all,
I wonder if there is a way of inserting more than one raster into a map made with ps.map. This is possible with vectors, is it possible with rasters?? how??
cheers and thanks to all
Francesco
g.manual ps.map:
...
For each ps.map run, only one raster map layer (or set of layers or imagery group; see below) can be requested.
...
r.patch could help

For each ps.map run, only one raster map layer (or set of layers or
imagery group; see below) can be requested. ...r.patch could help
also you could make a ps.map Encapsulated PostScript output map, then
place the EPS file(s) within another ps.map container map. Possibly
even a (mostly) blank one if say you want 4 maps arranged as so:

In the past I have use this to put a sub-set map in a corner showing
map of the country with a region box around the area of detail in the
main map. Worked ok but the resulting Postscript file was huge.

Hi Hamish,
thanks for your replay, I will try. In fact r.patch works fine if the
maps are of the same type, otherwise the reconstruction of the color map
can make bad results..
cheers

the eps within another ps.map is useful if the regions will be different
(e.g. overview map + detail map at different places on the page).
If you are interested in just overlaying maps in both the same region &
place on the page, it is best to just use r.patch for maps of the same
color maps, or as Glynn explained to me on the mailing lists a few
months ago, use r.mapcalc to create red,green,blue maps using the "#"
operator combined with if() statements to provide the order (see the
r.mapcalc help page). My less efficient method was to export a PNG dump
of the display monitor, then reload that image into GRASS as a new
raster.

Ok Hamish,
thanks for your suggestion, I will try to see what I can manage to do
with r.mapcalc
cheers
