[GRASS-user] image fusion in grasss 6.4.2

[Mark Seibel]

Hi,

> How can I do image fusion in grass gis 6.4.2?

One can use the r.his module and the r.composite module.

For example, to make a shaded and colorized DEM:
r.his h_map=<DEM> i_map=<shaded_reliefr> r_map=terrain.red
g_map=terrain.green b_map=terrain.blue

Then to make a composite raster:
r.composite red=terrain.red green=terrain.green blue=terrain.blue
levels=32 output=shaded_color_DEM

Hope that helps get things rolling in the right direction.

Mark
