Figure 10.4: Colored shaded relief map created with GRASS
to other formats supported by the r.out.* suite of commands in GRASS.
This includes creating a georeferenced TIFF that can be used with other
GIS software for those poor folks not using GRASS and/or QGIS. Let's
export the colored hillshade to a georeferenced TIFF that we can share:
r.out.tiff -t input=ancc6_comb output=ancc6.tif compression=packbit
The -t switch tells r.out.tiff to create a world file along with the TIFF. If
we use gdalinfo on the newly created file, we can see exactly what we
created.
