OT+ (OpenTopography Plus)

OpenTopography Plus (OT+) is a subscription service that enables one-stop, easy-to-use access to the highest quality lidar topography for the US. High resolution topographic data from authoritative sources such as the U.S. Geological Survey and NOAA are accessible without the need for specialized software or local compute resources, saving you valuable time and money.

OT+ subscribers can quickly access and download lidar point clouds and digital elevation models (DEMs / height maps), and use OpenTopography's powerful on-demand processing tools to generate custom topographic products including hillshades, contour lines, change maps, and other visualizations and products with just a few mouse clicks.

OT+ Features:


    Unlimited monthly access to lidar point cloud and digital elevation models (DEMs / height maps) covering the vast majority of the US. Datasets include the USGS 3D Elevation Program (3DEP), NOAA Coastal Lidar, and Polar Geospatial Centers DEMs covering polar regions of Earth. Browse data available via OT+



    On-demand, fast, browser-based processing tools: Generate custom DEMs (inc. DTMs, DSMs), contour lines, topographic hillshades and other raster-based derivatives and visualizations, 3D point cloud visualizations, hydrology products, and topographic change maps.



    Per job processing limits: 500 sq km for high resolution DEMs, up to 250 million points (roughly 10-50 sq km) for point cloud download and processing.

OT+ is available as an annual or monthly subscription. To purchase, click on the payment links below (via CognitiveEarth).
