Attention!

This page is under construction

See Trac wiki page for the development of the dataset.

Future GRASS GIS Sample Dataset (reference for other datasets, under development)
Original North Carolina GRASS Sample Location (map names partially standardized, content partially standardized, currently used dataset, to be depreciated)
Piemonte, Italy (map names not standardized, content not standardized, work in progress)

Compute slope, aspect and profile curvature of the terrain:

g.region raster=elevation
r.slope.aspect elevation=elevation slope=slope aspect=aspect pcurvature=profile_curvature

Visualize digital elevation model with shaded relief:

g.region raster=elevation
r.relief input=elevation output=shade
d.shade shade=shade color=elevation

GRASS GIS manual (currently using original, not fully compliant North Carolina GRASS Sample Location)
NCSU Geospatial Modeling and Analysis course and other NCSU OSGeoREL courses (currently using original, not fully compliant North Carolina GRASS Sample Location)

g.rename for changing names of individual raster and vector maps
g.rename.many for renaming large amount of maps (to standard names or to/from different language)
r.in.proj and v.in.proj for importing data with different coordinate system
