Agricultural Non-Point Source (AGNPS) Water Quality Modeling in a GIS Environment Stephen George Carpenter This thesis project outlines the development and implementation of a complex GIS project in a government agency. The objective of the project was to integrate a public domain GIS package (GRASS) with a commercial structured query language database in order to undertake Agricultural Non-Point Source (AGNPS) water quality modeling. Three general areas of GIS technology were investigated consisting of technical issues involved in linking GIS; the model; database development; and a discussion of system performance from an institutional perspective.
