Several no-data areas are present in the source data due to lack of data availability. Some other areas display as data gaps when the service is viewed at statewide scales, but display normally when zoomed in to larger scales. We hope to address the no-data areas and small-scale data gaps in future updates to this service.
The DEMs have not been hydrologically conditioned. Elevation units are Meters. The Vertical Datum for the DEMs is NAVD88.
WI DNR acknowledges the USDA Natural Resources Conservation Service, USGS, FEMA, the Southeastern WI Regional Planning Commission, and the individual counties listed above, for making source data available.
