Benchmark’s Geographic Information System (GIS) staff uses ESRI ArcView® software to support wetland delineation and construction projects, environmental sampling, and other field services. Benchmark staff uses digital geographic information (e.g., USGS maps, Federal Emergency Management Agency maps, National Wetland Inventory maps) to develop project maps prior to the initiation of field activities (e.g., site location maps, sample station maps, and habitat maps). Field data collected by Benchmark scientists are combined with existing information to develop comprehensive data bases.
