DESCRIPTION

r.object.geometry calculates form statistics of raster objects in the input map and writes it to the output text file (or standard output if no output filename or '-' is given), with fields separated by the chosen separator. Objects are defined as clumps of adjacent cells with the same category value (e.g. output of r.clump or i.segment).

By default, values are in pixels. If values in meters is desired, the user can set the -m flag. If the current working region is in lat-long or has non-square pixels, using meters is recommended.

Statistics currently calculated are exactly the same as in v.to.db (except for compact_square and mean coordinates):

NOTES

More statistics might be added in the future.

EXAMPLE

g.region raster=soilsID
r.object.geometry input=soilsID output=soils_geom.txt
