This feature layer contains Wisconsin hydro flowlines, area hydrography features and culvert lines created and developed by Wisconsin Department of Natural Resources DNR IT GIS Section as part of a pilot project to remap rivers, lakes and streams in Wisconsin coastal counties and HUC 8 watersheds at a scale of 1:5,000 (also referred to as 5k Hydro). WDNR staff used the most current Lidar DEM for each county as the input to the ACPF toolbox to create accumulation derived flowpaths. Waterbody area features and culverts were developed using Lidar breaklines, existing 24k GIS features, and digitization from multi-year aerial photography. Collection protocols followed USGS NHD digital elevation hydrography creation guidelines.Data DictionaryThis pilot project was 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 # NA21NOS4190086Dataset last Updated 4/22/2025.

Ecological Landscapes of Wisconsin are aggregations of NHFEU (National Hierarchical Framework of Ecological Units) subsections that have been assigned descriptive names. The Ecological Landscapes of Wisconsin are represented on a May, 1999 map prepared under the direction of the DNR Division of Land Ecosystem Management Planning Team.The NHFEU concept, developed by the USFS, is considered one of the oldest and best-documented ecosystem classification schemes at the federal level. The NHFEU has been refined over the years as new information becomes available to identify lower levels of the hierarchy.

This service is NOT for download but may be viewed in web maps and apps.Georeferenced Statewide Bedrock Geologic Map of Wisconsin, 1982. The Statewide Bedrock Geologic Map of Wisconsin was developed to provide a reliable, accurate and detailed representation of the state’s subsurface geology. It supports a variety of applications, including geological research, land-use planning, resource management, environmental conservation, education, public outreach, and policy development. By offering insights into the composition, structure, and distribution of bedrock formations, the map aids in identifying potential geological hazards and areas of scientific or ecological significance and helps planners, researchers, and decision-makers make informed choices.

The statewide geologic map symbol for each formation is standardized for consistency and can be found in the accompanying legend. The legend provides essential information, including formation names, lithologic descriptions, geologic age, and the symbology used in the dataset. This map and its data were developed by UW Extension-Geologic and Natural History Survey (WGNHS), Meredith E. Ostrom. Visit WGNHS Maps & Publications search for WGNHS maps and contact WGNHS at info@wgnhs.wisc.edu with any questions about this map or data. The map was georeferenced for use in this service by the Wisconsin DNR Bureau of Drinking Water and Groundwater, Water Use Section. For any questions contact the Bureau of Drinking Water and Groundwater GIS Analyst at DNRDGGISAPPS@wisconsin.gov. This data was mapped at a very small scale (ranging from 1:5,000,000 to 1:500,000), making it unsuitable for detailed local analysis or site-specific decision-making. Users are advised to consult local or higher-resolution datasets when conducting detailed analyses or making critical decisions.

This data set is a polygon feature layer representing Wisconsin DNR Geographic Management Units (GMUs). GMU boundaries are subject to review and periodic revision by DNR management.

This layer consists of a 1:250,000-scale polygon coverage containing depth-to-bedrock estimates used in preparing the GCSM for Wisconsin. The primary source for this data layer is a 1973 map at 1:1,000,000 scale published by the WGNHS and USGS. Where more recent information was available, the USGS updated the 50-foot and 100-foot contours of the depth-to-bedrock map at a scale of 1:250,000. Soil associations data, and other information,were used to add a 5-foot contour to the data layer.See the usage documentation (https://www.arcgis.com/home/item.html?id=e1e89ae505594459a46407f1daf4ad5d) and the Full report (https://www.arcgis.com/home/item.html?id=fd4d0c43abc04b4ab915586d9a0e89dd) for more information.

Sensitive Areas of Lakes are designated as Critical Habitat Areas in Wisconsin. These areas comprise of aquatic vegetation identified by the Wisconsin Department of Natural Resources as offering critical or unique fish and wildlife habitat, including seasonal or life stage requirements, or offering water quality or erosion control benefits to the body of water. Wisconsin law mandates special protections for these critical habitats. Critical Habitat Designation is a program that recognizes those areas and maps them so that everyone knows which areas are most vulnerable to impacts from human activity.

This data set is a polygon feature class representing Wisconsin DNR Turkey Management Zones. Turkey Management Zones indicate the areas with various turkey hunting regulations throughout Wisconsin. Hunting regulations may vary between and within zones. Users should consult the most recent Hunting Regulations Handbook to determine which regulations apply to which zones, or portions of zones.

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 1988-2015.

Note: This service is only for using online; full resolution downloads are not supported. Hillshade image service created from Digital Elevation Models (DEMs) derived from county-produced LiDAR covering several Wisconsin counties, with a vertical exaggeration factor of 2. This service was last updated in May, 2023. It can be used in conjunction with its associated Index layer, DEM and Hillshade from LiDAR - Index, to determine flight years of source LiDAR and resolution of source DEMs. Also see the Index layer item details for detailed information about counties included in this service and in related services: DEM from LiDAR (Units in Meters) and DEM from LiDAR (Units in Feet).Some areas display as data gaps (white artifacts) when the service is viewed at statewide scales but display normally when zoomed in to scales of approximately 1:1,000,000 or larger. We hope to address the no-data areas and small-scale data gaps in future updates to this service. The source DEMs have not been hydrologically conditioned. The Vertical Datum for the DEMs is NAVD88.

The Hillshade is intended for visualization of the landscape, rather than analysis. When queried, the Hillshade pixel values do not indicate elevation; instead, the pixel values range from 0 to 255 because the image is rendered as an 8-bit greyscale image. If elevation values are needed, use the LiDAR-Derived DEM Imagery Layer.

WI DNR acknowledges the USDA Natural Resources Conservation Service, USGS, FEMA, the Southeastern WI Regional Planning Commission, and the individual counties listed in DEM and Hillshade from LiDAR - Index, for making source data available.
