The bare earth digital elevation models (DEMs) derived from aerial LIDAR projects are some of the most up-to-date, accurate and precise models of the Earth’s surface. The DEM format is very familiar to most users and can be used in a wide range of software. However, users should be familiar with the data source and processing guidelines for the DEMs. This presentation will explain some of the key steps in using LIDAR to create bare earth DEMs, especially those which affect modeling water flow. Several examples of how the LIDAR point cloud can be used to improve localized surface modeling will be discussed.
