Designing a Geodatabase for Your Project: A Wetlands Delineation Example Track: Database Design, Automation, and Management Author(s): Naomi Kalman, Ingrid Hogle, Joshua Viers The key to successful geodatabase design in ArcGIS 8.3 is laying out the project objectives before you begin. Our team at the Information Center for the Environment at UC Davis is mapping for the U.S. Fish and Wildlife Service, as part of the National Wetlands Inventory (NWI). Our geodatabase must facilitate heads-up digitizing by multiple people and integrate seamlessly with the rest of the national inventory. We delineate wetlands using DOQQs combined with ancillary information such as hydric soils and topography. A personal geodatabase contains our wetlands polygons in a feature dataset and other geodata as stand-alone feature classes. We use a topological rule set within the feature dataset to maintain feature integrity, and an existing NWI tool manages attribution and error checking. We assigned geographic work areas and outlined procedures for synchronizing the data and creating backups.
