PE&RS June 2006

This example from the Hayman fire in the Colorado Front Range shows how multi-temporal lidar data can be used for change detection to not only extract information about the bare earth change, but vegetative change as well. Pre- and post-fi re imagery is overlaid on pre and post bare earth lidar-derived Digital Elevation Models (DEMs). Statistically significant bare earth change one year after the fire is shown from an increase (red) to a decrease (blue) in elevation. Also, the points discarded to create the bare earth DEM are displayed to show the vegetation change before and after the fire. Points are colored by height above ground from green (low) to red (high). The U.S. Geological Survey has created the Center for LIDAR Information Coordination and Knowledge (CLICK) to help provide lidar users with better access to existing raw (unfiltered) point cloud lidar datasets for scientific applications such as these. CLICK also hopes to help improve coordination and communication among users in the lidar community to help facilitate innovative lidar research.
