Nonpoint source pollution modeling of an agricultural watershed within a geographic information system
… the watershed-scale, resource managers and researchers have depended on the geographic information system (GIS) technology to determine input parameters and display output from models. There have also been numerous attempts to link GIS with lumped models to extend both the scope and scale of the …

Model linkages between a hazardous waste transportation impact/risk assessment model and a transportation planning model in a geographic information system environment
… can readily use. For outputs, a geographic information system (GIS) can provide an effective means for graphical display of results and product generation. The objectives of this Thesis are to develop programs and procedures linking Radtran and Tranplan in a GIS environment (ARC-INFO) to …

Effects of land use on oxygen uptake by microorganisms on fine benthic organic matter in two Appalachian mountain streams
… determined using infrared aerial photographs. ARC/INFO was used to obtain land use areas for various land uses. Oxygen uptake rates were measured using a Gilson differential respirometer, at ambient temperature and 20°C. Temperature was the most important factor influencing oxygen uptake rates …

Use of a Geographic Information System for Determining White-Tailed Deer Habitat Use in the Northern Black Hills of South Dakota and Wyoming
… Wyoming (USA) was evaluated using the geographic information system (GIS) software, PC ARC/INFO. Summer and winter habitat use was determined by plotting point observations and home ranges of telemetered deer on digital land-use maps. Percentages of habitat types within the study area, deer home …
