These examples were created using the Spearfish dataset. Spearfish is an example dataset for GRASS that contains raster, vector, imagery, sites, and other data. It is available freely from the GRASS ftp sites. Questions or comments should be e-mailed here.

	Digital elevation model (DEM) map layer for Spearfish, South Dakota.
	3-D view of the DEM map layer. GRASS can display 3-D data either as wire-frame (shown here) or as a solid surface.
	Aspect map created from a digital elevation model (DEM) using the r.slope.aspect tool.
	GRASS 3-D Image showing aspect raster layer over DEM.
	Digital elevation model raster map, roads vector map, and sites map illustrating the different types of data GRASS works with.
	SPOT satellite image at 10 meter resolution.
	Histogram for the SPOT satellite image.
	Cross sections taken using the GRASS r.profile tool. This data can then be read into other routines and used for different purposes such as stream channel erosion modeling and slope stability analysis.
	Raster map showing distance from streams for stream buffer zone analysis created using the r.buffer command.
	Roads and fields.
	Example of GRASS vector data for roads, streams, and railroads.
	Vector roads and sites maps.
	Soil map layer.
	1:24,000 scale geology map layer
	GRASS 3-D Image showing geology over elevation wire-frame.
