OpenTopography (OT – http://www.opentopography.org) is a web-based system for online management of high resolution topography data. OpenTopography provides efficient hosting for point cloud and raster topographic data, as well as geospatial tools for on-demand custom processing to generate derived products and visualizations. OT leverages high performance computing resources at the San Diego Supercomputer Center at the University of California, San Diego to allow users, regardless of expertise level, to access these massive topographic datasets and derived products for use in research, teaching, and commercial applications. OT currently hosts over a trillion lidar points and has over 25,000 registered users from global academia and industry. We are interested in building new partnerships with government and industry to leverage the OpenTopography platform, and to increase access to high resolution topography.
