[GRASS-dev] area() function in r.mapcalc

[Moritz Lennert]

Andy,

As I just saw your contribution to the addons: r.cell.area [1], please 
all note that 10 months ago MarkusM has implemented an area() function 
in r.mapcalc [2]. This is currently only available in trunk, but will 
thus be in GRASS GIS 7.4. This uses internal library functions which 
calculate area of the pixel taking into account the current projection 
system.
