GIS Concepts,ng conventions, there are certain principles common to all systems. At first, we briefly describe the GIS basics in general (for in depth information read Longeley et al., 2002, Clarke, 2002, or Burrough and McDonnell, 1998) and then we explain the principles of map projections and coordinate systems that are used to georeference the data.

Working with Vector Data,roads, railroads, streams, or utility networks, while areas can represent soil types, land use categories, lakes, or zoning in urban areas. Vector data are stored using their coordinates. In GRASS, the vector data model includes the description of topology.

Using GRASS: Application Examples, Spearfish data set. More complex application is included in the section focused on land use management. To save space, we use the command line mode throughout this chapter; however, the same tasks can be performed by accessing the commands using the TclTk interface or an interactive mode (see Section 3.1.3).

Working with Raster Data,when combined with map algebra, provides wide range of capabilities for spatial modeling, all of which would be impossible to cover within a single chapter. Therefore, this chapter provides the basic description of the tools; more can be learned from the manual pages, tutorials and publications prov
