Established an ARC/INFO based GIS to support environmental impact analysis for a proposed 760 mile, $1.2 billion natural gas pipeline system in Florida, Mississippi, and Alabama. This GIS managed and analyized data concerning vegetation, threatened/endangered species, cultural resources, wells, karst areas, waste sites, transportation systems, and various land uses. Developed automated biological and cultural survey data collection and integration methods utilizing Global Positioning Systems (GPS) as well as map and table production automation. The GIS database was used to develop a pipeline route siting model specifically designed to evaluate potential routing alternatives in order to minimize cultural and environmental impacts. Created over 2,000 maps and tables presenting route impacts for the environmental report.
