Funny Doug, you nearly read my mind here... -> "gdal/GRASS interface code"
Thanks,

Yann,
About all I can recommend is the vrt format tutorial,
http://www.gdal.org/gdal_vrttut.html, gdal, data model
http://www.gdal.org/gdal_datamodel.html, and driver tutorial,
http://www.gdal.org/gdal_drivertut.html , etc in the gdal online
documentation. You might look at the existing gdal/GRAS

Unfortunately, in wxGUI maps are rendered to files (by d.* modules)
and then read to wxGUI. (That's probably why it is slow.)

Thank you Doug,
yes r.patch is a good alternative, but it means writing to disk etc.
Was more thinking of a display memory thingy.
Been thinking about the virtual rasters indeed, maybe will have a
look, any C code page you could direct me to?
Cheers,
Yann

Yann,
If I have a large number of layers, I usually do it from a command line or
with a script. I done r.patch with over 100 layers in one command ( before
I discovered gdalbuildvirt :-))

Yes, it is my favorite feature. I use it even to find and add one map.
However, there is some issue with many layers in layer manager. If you
load more than 20 (?) layers (maps) only some of them will be
rendered. There

Thanks !

I am dealing with hourly Microwave data that are not covering the
whole World in each layer.
To have a decent presentation map of the data, I'd like to get a set
(say 30-50 layers) displayed in one go.
OK I could do it with the png driver in a script (which is what it may
eventually become), but
