ABSTRACT
Most environmental data is inherently spatial. That means that the observation was taken at a specific location in map coordinates (X and Y) and depth (or elevation). Often seeing the data in its spatial context imparts more information content than seeing it as a text-only presentation. Using computerized mapping to help understand this spatial context makes sense for many projects. This chapter covers issues related to computerized mapping, including software for creating maps, displaying your data, contouring and modeling, and specialized map displays.
