Hi Stefan,
Sure, that makes all sense! I am not used to DEM-realted indices, but I could
have just thought a little...Thanks a lot!

Hi Brenado,
TPI is rather simple and can be computed with r.neighbors + r.mapcalc:
r.neighbors -c input=dem output=dem_avg_9 size=9
r.mapcalc expression=”TPI_9=dem-dem_avg_9”
g.remove -f type=raster name=dem_avg_9
Cheers
Stefan

Subject: [GRASS-user] TPI (terrain position index) in GRASS GIS
Hi everyone,
Do any of you know if we can calculate TPI (terrain position index) in GRASS
GIS?
Or should we go for other tools such as SAGA GIS?
Best wishes,
Bernardo Niebuhr
