Abstract
An Evaluation of LIDAR Vertical Accuracy in Grand Canyon, Arizona
Track: Environment Management
Author(s): Steven Mietz, Philip Davis, Keith Kohl
LIDAR was flown over the Grand Canyon in March and September of 2000 to assess its ability to provide a relatively low-cost, ecosystemwide change detection tool. Determining the error associated with the elevation values of the LIDAR points was necessary to ensure true change in the target resource being measured. This paper shall present the methods used to check the vertical accuracy of the LIDAR points, describe the results, and offer conclusions regarding the potential utility of using LIDAR as a change detection tool for fine- and coarse-grained sediment storage monitoring, flow modeling, vegetation abundance, and cultural site monitoring.
