The mapped landslide polygons depict landslide area boundaries located near the Hoosier National Forest. Landslide area boundaries were determined by using the 2016-2020 State of Indiana Digital Elevation Model (DEM) data set. A slope angle DEM derivative data layer was created using GIS software to visually depict landslide geomorphological features. Indiana Imagery DEM 2016-2020 Deschamps & Lange Burns & Madin 2024 GIS software was used to produce a slope DEM derivative data layer from the 2016-2020 State of Indiana DEM to quantify and visualize terrain landforms and identify landslide areas. The slope DEM derivative GIS layer visualizes the DEM based on the slope (gradient or steepness). When determining landslide extents, several geomorphological features such as the main scarp, flanks, and toe were visually identified using the slope derivative DEM data layer that was created by GIS software.
