<p class=MsoNormal><font size=3 face="Times New Roman"><span style='font-size:
12.0pt'>Hi all,<br>
<br>
I have a raster map, lat/long, 0.5 degrees resolution. I want to develop solar
radiation and related maps maps using r.mapcalc. This requires refering to each
cell's latitude and longitude, i.e. the equations will include the cell's
latitude and longitude. How do i do this in GRASS? Is there like an intenral variable
that indexes each cell's coordinates?<br>
<br>
thanks,<br>
