The purpose of this survey was not to map all wetlands and deepwater habitats, but rather, to use aerial photointerpretation techniques to produce thematic maps that show, in most cases, the larger types that can be identified by such techniques. The objective was to provide better geospatial information on wetlands than found on the USGS topoquads. <DIV STYLE="text-align:Left;"><DIV><DIV><P><SPAN>NWI digital data files are records of wetlands location and classification as defined by the U.S. Fish & Wildlife Service. This dataset was the original digital wetland inventory (1978). The digital data as well as the hardcopy maps that were used as the source for the digital data are produced and distributed by the U.S. Fish & Wildlife Service's National Inventory project. Classification of wetlands is based on the Cowardin Wetland Classification system. NWI maps were compiled through manual photointerpretation (using Cartographic Engineering 4X Mirror Stereoscopes) of NHAP or NAPP aerial photography supplemented by Soil Surveys and field checking of wetland photo signatures. Delineated wetland boundaries were manually transferred from interpreted photos to USGS 7.5 minute topographic quadrangle maps and then manually labeled. Quality control steps occurred throughout the photointerpretation, map compilation, and map reproduction processes. </SPAN></P></DIV></DIV></DIV> USFWS National Wetland Inventory NWI Wetlands 1978 Chad Fizzell EGLE GIS Specialist Jeremy Jones EGLE GIS Specialist jonesj28@michigan.gov False Jeremy Jones dataset 0 Simple FALSE 0 TRUE FALSE NationalWetlandInventory1978 Feature Class 0 OBJECTID OBJECTID OID 4 10 0 Internal feature number.
