Lidar-derived digital surface and elevation models of a stream channel
Due to a lapse in appropriations, the majority of USGS websites may not be up to date and may not reflect current conditions. Websites displaying real-time data, such as Earthquake and Water and information needed for public health and safety will be updated with limited support. Additionally, USGS will not be able to respond to inquiries until appropriations are enacted. For more information, please see www.doi.gov/shutdown
The above image is a rendering of a lidar-derived digital surface model overlaying a digital elevation model of a forested stream channel in central Iowa. The vegetation makes optical identification of the presence of water in channels difficult. The digital models are being used to measure the structure of vegetation adjacent to channels in an attempt to identify features that indicate the presence of surface water.
