Current PE&RS Cover

PE&RS September 2008

This month’s cover shows the wealth of information that can be extracted from a single light detection and ranging (lidar) collection. This image, created by using only lidar data over downtown Sioux Falls, South Dakota, is a multi-band combination of bare earth elevation, height above bare earth, laser return intensity and non-bare earth slope. Using these combinations of derivatives from the raw data we can create pseudo-imagery that can be used to extract information such as bare earth topography, vegetation and structural information. It is this wealth of information that can be achieved by using lidar technology that is prompting the USGS to work with many partners in the development and hopeful creation of a future National Lidar Dataset. This month’s Highlight article discusses the need for a National Lidar Dataset, and how the USGS is beginning to take the lead in the creation of such a valuable remote sensing product. For more information on this image or the National Lidar Dataset, contact Jason Stoker, Physical Scientist, U.S. Geological Survey, jstoker@usgs.gov, or visit our USGS Center for Lidar Information Coordination and Knowledge page (http://lidar.cr.usgs.gov).
