Full Details

Title:

DEM (30m), Wisconsin 1998

Description:

This Grid-format Digital Elevation Model (DEM) is a raster representation of land elevation of Wisconsin. This DEM ('demgw930') is derived from the 7.5-minute DEMs published by the US Geological Survey (USGS). This DEM is an integer grid, with elevation units in meters relative to the National Geodetic Vertical Datum of 1929 (NGVD 29). The 7.5-minute DEMs have a 30-meter pixel cell size, or resolution. More current or detailed DEMs may also be available directly from the USGS. For more information, refer to the USGS DEM Fact Sheet: The spatial extent this data layer is the state of Wisconsin, plus a buffer around the perimeter extending approximately 5,000 meters beyond the state boundary. The DEM includes elevation values every 30 meters or 98.4 feet. Elevation units are in meters. ArcView with the Spatial Analyst Extension, ArcInfo/ArcGIS Grid, or comparable GIS software is needed to use the Grid format data meaningfully. Time period extent for this content is 1990-2000.
