GRASS GIS Standardized Sample Datasets

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
