See Trac wiki page for the development of the dataset.
List of datasets
- 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)
Examples
Computing slope and aspect
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
-
Aspect (North Carolina, USA)
-
Slope (North Carolina, USA)
-
Profile curvature (North Carolina, USA)
-
Aspect (Piemonte, Italy)
-
Slope (Piemonte, Italy)
-
Profile curvature (Piemonte, Italy)
Visualizing shaded relief
Visualize digital elevation model with shaded relief:
g.region raster=elevation r.relief input=elevation output=shade d.shade shade=shade color=elevation
-
North Carolina, USA
-
Piemonte, Italy
Where are the datasets used
- 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)
Tools to help with managing a dataset
- 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
