Six new NCALM (National Center for Airborne Laser Mapping) datasets covering portions of California, Colorado, Louisiana, and Wyoming are now available from OpenTopography. NCALM is an NSF-funded center that supports the use of airborne laser mapping technology (a.k.a. lidar) in the scientific community and is jointly operated by the Department of Civil & Environmental Engineering, Cullen College of Engineering, University of Houston and the Department of Earth and Planetary Science, University of California, Berkeley. OpenTopography is the primary distributor of NCALM data.

The National Science Foundation (NSF) has renewed funding for OpenTopography, a science gateway that provides online access to Earth science oriented high resolution topography data and processing tools to advance understanding of the Earth’s surface, vegetation, and built environment. OpenTopography is a comprehensive platform for open access to high-resolution (1 meter pixel resolution or better) and global topographic data that is utilized by an international community of researchers, educators, government agencies, industry and hobbyists.
OpenTopography is a collaborative project... more

Updated Land Information New Zealand (LINZ) datasets covering portions of the South Island are now available through OpenTopography. The dataset, "Canterbury, New Zealand 2020-2023" and "Southland, New Zealand 2020-2024" have each had addendums added to their respective collections. These datasets are available through an ongoing collaboration between OpenTopography and LINZ as part of the LINZ National Elevation Program. These addendums collectively add over 12,000 km2 of high resolution topographic data over the South Island of New Zealand (see areas in red on map below).

The most recent version of the Copernicus Digital Surface Model (DSM) is now available via OpenTopography. As of July 23rd 2024, OpenTopography is supplying the DGED 2023_1 version of the European Space Agency (ESA) Copernicus GLO-30 and GLO-90 DSMs. The Copernicus datasets are derived from the WorldDEM which was generated from radar satellite data acquired during the TanDEM-X Mission. This dataset is a DSM, therefore elevation measurements represent the surface of the Earth including buildings, infrastructure and vegetation. The OpenTopography portal provides easy GUI-based access, as well... more

Three new NCALM (National Center for Airborne Laser Mapping) seed datasets covering portions of Texas, Arkansas, and Idaho are now available from OpenTopography. The dataset, Characterizing Alluvial Channel Bank Erosion with Lidar, TX 2023 was collected for Mariel Nelson at the University of Texas to help characterize alluvial channel bank erosion along the Trinity River near Houston, TX.
The dataset, Mapping Landscape Evolution in the Ozarks, AR 2023 was collected for Chelsea Moran at the University of Arkansas to help understand the spatial and temporal distribution of large rock blocks and... more

The Land Information New Zealand (LINZ) dataset, Waikato, New Zealand 2021, has been updated with additional data. This dataset now contains over 270 billion lidar points and covers roughly 25,000 km2, making it one of the larger datasets in the OpenTopography catalog. This dataset is available through an ongoing collaboration between OpenTopography and LINZ as part of the LINZ National Elevation Program.

Two new NCALM (National Center for Airborne Laser Mapping) seed datasets are now available from OpenTopography. The dataset, "Monitoring the Mass Balance of Eklutna Glacier, AK 2023" was collected for Caroline Brisbois at the Institute of Culture & Environment, Alaska Pacific University and aims to compare lidar versus structure from motion photogrammetry for monitoring the geodetic mass balance of the Eklutna Glacier east of Anchorage, Alaska.
The dataset, "Detecting Changes in Hillslope Geomorphology Due to Thawing Permafrost, AK 2023" was collected for Zena Robert at Montana State... more

OpenTopography is pleased to announce a visualization enhancement for topographic differencing results that allows users to visually compare the change between two overlapping datasets using an image slider to compare hillshades. This slider is produced by default for all differencing jobs and is displayed at the bottom of the results page. In regions with multi-temporal lidar coverage, topographic differencing can be used to quantify the change in the surface environment for a variety of tectonic, geomorphic, and anthropogenic processes including earthquakes, volcanic eruptions, river... more
