[GRASS-user] raster analysis sectorwise as in a pie chart

[Otto Dassau]

Hi, 

I would like to analyse elevation data (slope, aspect, etc) around a point with
a defined radius. For my analysis I would like to devide that circle into
several sectors 1,5,10,x degree steps, like a pie. 

Is that possible in GRASS? Are there people who did something similar? Any hints
and ideas are welcome.

regards,
 Otto
