Info: This is an archived copy of the data held at UW-Madison. For the most current data available please visit: https://data-wi-dnr.opendata.arcgis.com/ [WDNR obtained these USGS-produced NED 10-meter resolution data from MapMart, a division of Intrasearch, Inc., in July 2009. No spatial metadata from USGS was provided, so the data source, processing method, and resolution at the time MapMart obtained the data from USGS are not available. USGS continues to improve the NED 10m product, and provides shapefiles of spatial metadata when downloading the data. The NED data were mosaicked to cover Wisconsin, projected to WTM83(91), and clipped using a 5000 meter buffer of the state perimeter. Separate data sets of hillshading, percent slope, and slope aspect were derived. Additional terrain derivatives for hydrologic modelling or cartographic purposes may be produced in the future. After USGS completes the updates of the NED 10m product, it may be advisable to replace all of these layers.
