[GRASS-dev] G_distance( ) problem in r.slope.aspect?

[Markus Metz]

Try

r.in.gdal input=as_dem_30s.bil output=dem_asia_hydrosheds_30s
# check extents and range
r.info dem_asia_hydrosheds_30s

# set the region
g.region -p rast=dem_asia_hydrosheds_30s

r.colors map=dem_asia_hydrosheds_30s rules=srtm
r.slope.aspect elevation=dem_asia_hydrosheds_30s
slope=dem_asia_hydrosheds_30s_slope format=percent
r.colors map=dem_asia_hydrosheds_30s_slope color=slope

# check result
r.info dem_asia_hydrosheds_30s_slope
