Title Assessing LiDAR Elevation Data for KDOT Applications, Technical Summary.
Publication Date Feb 2013
Media Count 2p
Personal Author C. B. Young
Abstract LiDAR survey data may not replace traditional ground-based survey for applications that require centimeter or sub-centimeter accuracy, but the data available from these surveys may be perfect for many engineering applications. One such application is hydraulic modeling with HEC-RAS. Hydraulic models, used for flood-plain mapping and the evaluation of bridge backwater effects, require detailed elevation maps for the stream channel and floodplain. These data are difficult to obtain using traditional aerial survey techniques due to riparian vegetation that obstructs the view of the stream channel. Another potential application for LiDAR data is earthwork calculations (cut/fill analysis) for preliminary route planning purposes. Because LiDAR surveys are fairly new, the applications and limitations of these data have not been explored. This report presents an overview of LiDAR technology, applications, and error characteristics. Over fifty research papers and reports were reviewed.
