Wisconsin Wetland Inventory Point 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. Wetland features and ponds that were too small to draft as a polygon were given a point symbol. The photos were scanned and the wetland information digitized into a GIS. Data mapped between 1988-2016. Visible below 1:95,000.   Updated mapping in Wisconsin is ongoing and the goal is to replace all point symbols with a boundary.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 is too large to download statewide from the Open Data site.  It is recommended that users download a filtered version of it by zooming into an area of interest on the map interface.
