See Trac wiki page for the development of the dataset.
List of datasets
Already published:
- North Carolina GRASS Sample Location (2007, map names partially standardized, content partially standardized, currently used dataset, to be deprecated)
- Piemonte, Italy (2012, map names not standardized, content not standardized, work in progress, see below)
- Spearfish, USA (to be phased out, 1986)
Planning - Future standardized datasets
- GRASS GIS North Carolina USA Sample Dataset (reference for other datasets, under development)
- GRASS GIS Piemonte Italy Sample Dataset
- GRASS GIS World Sample Dataset
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
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
- Python script std_dataset_display.py for generating some maps and images
