Wisconsin Department of Natural Resources - Wisconsin Wetland Inventory Point Layer (stereo-pair mapping)

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. If the data are needed statewide, the full file geodatabase is available for download at https://www..arcgis.com/home/item.html?id=200c06fc04074ef7ae24c0b74737b187This layer should be used in conjunction with the following layers to get full coverage:Wisconsin Wetland Inventory Polygon Layer (stereo-pair mapping)Wisconsin Wetland Inventory NWI Polygon Layer (LiDAR based mapping)Wisconsin Wetland Inventory Filled/Drained Polygon Layer (stereo-pair mapping)Wisconsin Wetland Inventory Filled/Drained Point Layer (stereo-pair mapping)For more information on Wisconsin DNR Wetland Mapping visit: https://dnr.wisconsin.gov/topic/Wetlands/inventory.html
