DESCRIPTION

36       r.info reports some basic information about a user-specified raster map
37       layer.  This map layer must exist in the user's current  mapset  search
38       path.   Information about the map's boundaries, resolution, projection,
39       data type, category number, data base location and  mapset,  the  time‐
40       stamp  and history are put into a table and written to standard output.
41       The types of information listed can also be found in the cats,  cellhd,
42       and hist directories under the mapset in which the named map is stored.
43
44       The  user can save the tabular output to a file by using the UNIX redi‐
45       rection mechanism (>); for example, the user might save a report on the
46       soils map layer in a file called soil.rpt by typing: r.info map=soils >
47       soil.rpt
48
49       Below is the report produced by r.info for the raster map slope in  the
50       Spearfish sample data base.
