DESCRIPTION
r.info reports some basic information about a
user-specified raster map layer. This map layer must exist
in the user's current mapset search path. Information
about the map's boundaries, resolution, projection, data
type, category number, data base location and mapset, and
history are put into a table and written to standard
output. The types of information listed can also be found
in the cats, cellhd, and hist
directories under the mapset in which the named map is
stored.
The user can save the tabular output to a file
by using the UNIX redirection mechanism (>); for example, the user
might save a report on the soils map layer in a file called
soil.rpt by typing:
-
r.info map=soils > soil.rpt
Below is the report produced by r.info for the raster map
geology in the Spearfish sample data base.
