Obtain working demo of SG3d.
The demo comes with a minimal amount of sample data. This SG3d program
module was compiled to run without installing GRASS, but in order to use
SG3d effectively with your own data, you should install and learn to use
GRASS. GRASS is a powerful Geographic Information System that allows
researchers to use a variety of statistical and spatial analysis techniques
to evaluate their data. SG3d helps in this evaluation by providing an
easy to use display mechanism to view 2D data as a surface in 3D space.
For more information on how to obtain the GRASS GIS software, see GRASS 4.1 Release Information.
Available with the release is a complete set of sample data for
an area near Spearfish, S.D. which contains dozens of data "layers" such as
soil types, geology, land use, elevation, roads, streams, etc.
