On-Demand Vertical Differencing of USGS 3DEP and NOAA Lidar Topography

Oct 25, 2023

OpenTopography has expanded our on-demand vertical differencing (a.k.a. topographic change detection) tools to the U.S. Geological Survey’s (USGS) 3D Elevation Program (3DEP) and the National Oceanic and Atmospheric Administration (NOAA) coastal lidar collections. This update makes it possible to use OpenTopography's tools to compute topographic change for more than 20% of the contiguous United States that are covered by more than one high resolution lidar topographic dataset.

New SfM Dataset over Mount Rainier, Washington

Sep 5, 2023

OpenTopography has recently added a new structure from motion (SfM) dataset over Mount Rainier in Washington State. This dataset was collected by the National Park Service Mount Rainier (MORA) Geology Division in cooperation with the Alaska Region Office (AKRO) in September 2021. This dataset provides a unique, high-resolution survey of the geology, glaciology and overall topography of Mt Rainier and its surrounding areas. Both the digital surface model and component orthophotos are available through OpenTopography.

Pima Association of Governments makes lidar data for Pima County open access on OpenTopography

Jul 10, 2023

Pima Association of Governments (PAG) has partnered with OpenTopography to make the most recent high-quality USGS 3DEP light detection and ranging (lidar) dataset over Pima County, Arizona “open access” via OpenTopography - an online, public, geospatial data portal. Lidar is a remote sensing method used to create high resolution three-dimensional representations of the Earth's surface, including buildings, streets, vegetation, and the ground.

New Bay of Plenty, Tasman Bay, and Coastal Otago New Zealand datasets

Mar 7, 2023

OpenTopography has recently added three new datasets over New Zealand that collectively cover almost 12,000 km 2. The datasets cover the Southeast coast and the Tasman and Nelson regions of the South Island, as well as the Bay of Plenty region of the North Island. These datasets are available through an ongoing collaboration between OpenTopography and LINZ that makes OpenTopography the primary distribution platform for point cloud data collected as part of the LINZ national elevation program.

GEDI L3 gridded data now available through OpenTopography

Mar 1, 2023

The Global Ecosystem Dynamics Investigation (GEDI) Level 3 gridded mean ground elevation and mean canopy height are now available through OpenTopography. These products are a subset of the level 3 gridded land surface metrics that are available from the NASA ORNL DAAC. The GEDI instrument is onboard the International Space Station, resulting in data coverage from -52 to 52 degrees latitude.
