Wisconsin Wetland Inventory Filled/Drained Polygon Layer (stereo-pair mapping), WI DNR

Created By:

Wisconsin Department of Natural Resources

Description:

Original Wisconsin Wetland Inventory maps were created using stereo-pair, 9”x9”, B/W (NIR) aerial photography flown at a scale of 1:20000 (1in=1667ft). Each photo covered four Public Land Survey System Sections with each section being approximately 1 square mile. Wetland delineations were drafted onto the photos using stereoscopes. The photos were scanned and the wetland information digitized into a GIS. Data mapped between 1988-2016. Visible below 1:95,000.Funded by the Wisconsin Coastal Management Program and the National Oceanic and Atmospheric Administration, Office for Coastal Management under the Coastal Zone Management Act, Grant #NA19NOS419008. This layer should be used in conjunction with the following layers to get full coverage: Wisconsin Wetland Inventory NWI Polygon Layer (LiDAR based mapping)Wisconsin Wetland Inventory Polygon Layer (stereo-pair mapping)Wisconsin Wetland Inventory Filled/Drained Point Layer (stereo-pair mapping)Wisconsin Wetland Inventory Point Layer (stereo-pair mapping) For more information on Wisconsin DNR Wetland Mapping visit: https://dnr.wisconsin.gov/topic/Wetlands/inventory.html For the Wisconsin Wetland Classification System used in the stereo-pair dataset visit: https://dnr.wisconsin.gov/sites/default/files/topic/Wetlands/WWI_Classification.pdf
