Characteristics of Urbanization in
Five Watersheds of Anchorage, Alaska: Geographic Information System Data
By Edward H. Moran
Abstract
The report contains 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 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. ArcView® 3.2 project, an ArcGIS® project, and 16 ArcExplorer2® projects are linked to the PDF file based report. Some of these coverages are large files over 10 MB. The largest coverage, impervious cover, is 208 MB.
ArcExplorer2® is available free for downloading at URL:
