Hi
I added new two modules to svn add-on.
r.area
Simple module available in almost every raster processing GIS
application. Calculates area size of clumped areas and ascribe these
values to these areas. Also allow remove small areas with size lower
than treshold. All that functionality can be attempted with few
existing grass commands (r.to.vect, v.db.addcolumn, v.to.db v.to.rast,
r.mapcalc sequentially) but I spend less time programing this module
than performing this set of operation (on rather huge map with over
100000 cluped areas)
r.convergence
specializing module reworked from SAGA. Calculate convergnece index for
given area based on DEM. Good wor detecting geomorphological lineaments.
It use different method for slope-aspect calculation than SAGA (but the
same as in GRASS r.slope.aspect), also can work in lat-long projections.
As always any comments, tests, suggestions and critics are welcome
Jarek
