ABSTRACT

 

3D images of LIDAR (LIght Detection And Ranging) data from the surface of the Prairie Complex of southwestern Louisiana reveal depositional, erosional, and structural features in great detail.  We have imaged publicly available LIDAR data in an interactive 3D virtual reality system created in the Virtual Reality (VR) Laboratory at the University of Louisiana at Lafayette.  Within this system we utilize specially designed VR tools to investigate, measure and delineate the features of the surface.  We identify faults, leveed channels, meander scars, overbank deposits, the Pleistocene scarp…the Coteau, faults, and eroded stream valleys.  We present a chronology of development of these features based on cross-cutting relationships within a nearly square area of data about 35 mi (60 km) on a side with Lafayette, Louisiana, near the southeastern corner and Opelousas, Louisiana, near the northeastern corner.
