Geographic information system (GIS) is a computer-based tool for mapping and analyzing things that exist and events that happen on earth. GIS technology integrates common database operations such as query and statistical analysis with the unique visualization and geographic analysis benefits offered by maps. These abilities distinguish GIS from other information systems and make it valuable to a wide range of public and private enterprises for explaining events, predicting outcomes, and planning strategies. As part of the Visualization endpoint for the Environmental Technology Verification Program, ESRI software will demonstrate database connectivity, geographic display and mapping functionality, and model interfaces, which are vital tools to site characterization, risk assessment, and groundwater remediation. These tools will also provide the inputs for 3-D modeling of contaminant plumes, and the decision support criteria for placement of injection/extraction wells.
