Abstract
The surface terrain model of Indiana was created using part of the National Elevation Dataset (NED)—a digital elevation information product for the United States—and newly created digital elevation models (DEMs). New digital elevation data replaced 275 of the 710 Indiana 7.5-minute quadrangles. This report describes the processes of 1) creating new DEMs, 2) merging the new data and the original NED into a new grid, and 3) creating images from the final data set. The revised digital elevation model for Indiana and parts of the surrounding states is available on a CD-ROM as a raster in ESRI grid format. This report also provides the background for the Indiana Geological Survey (IGS) Poster 5 and the forthcoming terrain image series.
