New Visualization Techniques to Analyze Ultra-High Resolution Four- dimensional Surface Deformation Imagery Collected With Ground-based Tripod LiDAR Kreylos, O - Institute for Data Analysis and Visualization (IDAV), University of California, One Shields Avenue, Davis, CA 95616 United States Bawden, G W- US Geological Survey, 3020 State University Drive East, Modoc Hall Suite 4004, Sacramento, CA 95819 United States Kellogg, L H - Department of Geology, University of California, One Shields Avenue, Davis, CA 95616 United States We are developing a visualization application to display and interact with very large (tens of millions of points) four-dimensional point position datasets in an immersive environment such that point groups from repeated Tripod LiDAR (Light Detection And Ranging) surveys can be selected, measured, and analyzed for land surface change using 3D~interactions. Ground-based tripod or terrestrial LiDAR (T-LiDAR) can remotely collect ultra-high resolution (centimeter to subcentimeter) and accurate (± 4 mm) digital imagery of the
