Well, I would like to have the possibility to export a raster with its colors
and legend.
Look at r.out.gmap in the addons:
http://grass.osgeo.org/wiki/GRASS_AddOns#r.out.gmap
Or you can do it by hand a bit like this:
# Export map to Google Earth tiles.
map=$1
# Export map as png and make null data transparent
g.region rast=$map
export `g.region zoom=$map -lg` # Get map bounds in Lat Long
r.out.png $map
mogrify -transparent white $map.png
# Georeference and reproject output
gdal_translate -a_srs EPSG:4326 -a_ullr $nw_long $nw_lat $se_long
$se_lat $map.png $map.tif
gdalwarp -t_srs EPSG:4326 -rc $map.tif $map\4326.tif
# Tile for Google Earth
gdal2tiles.py -title $map -forcekml $map\4326.tif $map
