This book was released on 1988 with total page 9 pages. Available in PDF, EPUB and Kindle. Book excerpt: Wisconsin Wetlands Inventory (WWI) maps prepared by the Wisconsin Department of Natural Resources (WDNR) were computerized to increase their versatility. Wetland boundaries and classifications determined by stereoscopic interpretation of 1:20,000 photographic aerial photography were field checked and drafted onto reproducible 1:24,000 photographic base maps. Computer software developed by WDNR was used to: 1) semi-rectify the photographic base to 7.5 minute U.S.G.S. quadrangles, 2) convert the digitized linework and classification codes to a polygon format, 3) report acreage by classification code, and 4) generate map overlays. The WWI maps have provided information for a variety of management, planning, and regulatory applications. Computer-plotted wetland overlays have been created for special needs: quantification of sandhill crane habitat, developing a non-point source pollution abatement plan, and regulating wetlands adjacent to navigable waters. The flexibility of a computer-automated wetlands inventory has enhanced WDNR's ability to carry out its management and regulatory mandates.
