Characteristics of Urbanization in Five Watersheds of Anchorage, Alaska: Geographic Information System Data

摘要

The CD-ROMs NAWQA(underline)CD1 and NAWQA(underline)CD2 contain environmental and urban geographic information system data for 14 sites in 5 watersheds in Anchorage, Alaska. These sites were examined during summer in 1999 and 2000 to determine effects of urbanization on water quality. The CD-ROM data sets are Environmental Systems Research Institute, Inc., shapefiles, coverages, and images. Also included are an elevation grid and a triangulated irregular network. Although the data are intended for users with advanced geographic information system capabilities, simple images of the data also are available. For user convenience, CD-ROM NAWQA(underline)CD1 includes an ArcView 3.2 project, an ArcGIS project, and 16 ArcExplorer2 projects.
