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

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


North Carolina (USA) dataset
Piemonte (Italy) dataset
Puerto Rico dataset
Czech Republic dataset

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

Where are the datasets used

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
