OT+ (OpenTopography Plus)

OpenTopography Plus (OT+) is a subscription-based program that enables access to our platform of user-friendly services applied to high resolution lidar topography data covering the vast majority of the US’s lower 48, Hawaii, and territories, as well as high resolution photogrammetric topography over the Arctic and Antarctic.

OT+ subscribers have access to OpenTopography’s user-friendly processing tools to generate and download point clouds, digital elevation models (DEMs), topographic hillshades, contour lines, and other visualizations and products with just a few mouse clicks.

OT+ enables users in government and industry to efficiently and easily access high resolution topography data without the need for specialized software or local compute resources, saving valuable time and money.

OT+ Features:


  • Unlimited jobs to access lidar point cloud and high resolution (1-2 meter spatial resolution) digital elevation models (DEMs) covering the vast majority of the US and the polar regions via the OpenTopography Portal. Datasets include the USGS 3D Elevation Program (3DEP), NOAA Coastal Lidar, and Polar Geospatial Centers DEMs over the Arctic and Antarctic. Browse data available via OT+




  • On-demand 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 vertical change maps.




  • Per job processing limits: 500 sq km for high resolution DEM data, up to 250 million pts/job (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 Cognitive Earth).

  • Coverage: The coverage areas shown are provided by the agencies responsible for these datasets. In rare cases, the data may not be available for the regions shown. OpenTopography federates access to these public domain datasets and lacks control over their availability and performance. As a result, we cannot guarantee 100% uptime or the completion of all user submitted requests.
  • OpenTopography does not guarantee the quality or accuracy of these data. Users should consult dataset metadata to determine if these data are fit for their purposes.
  • OpenTopography Account: An OpenTopography account is required to participate in the OT+ Pilot. Make an account here.
  • Multi-user Access: OT+ is designed for individual users only. For multi-seat/group access, please email info@opentopography.org.
  • OT+ Access: Access to OT+ is not instant. Upon registration and payment, an OT team member will grant you access to the system and you will receive an email notification that your enrollment in OT+ is complete.
