New 30m Digital Terrain Model Covering Continental Europe Now Available

Dec 1, 2022

OpenTopography is pleased to provide access to a unique Digital Terrain Model (DTM) for Continental Europe. Dr Tom Hengl at the OpenGeoHub foundation and his colleagues developed an Ensemble Machine Learning (EML) algorithm to predict the bare-earth terrain using publicly available Digital Surface Models (e.g. MERITDEM, AW3D30, GLO-30, EU DEM, GLAD canopy height). The EML was trained using over 9 million GEDI and ICESat-2 ground elevations.

Spring 2023 OpenTopography Webinar Series

Nov 21, 2022

OpenTopography invites you to join us for a series of weekly hour-long webinars beginning in March 2023. During the webinars, we will teach the basics of lidar, demonstrate how to use OpenTopography's growing set of on-demand processing tools, and present available resources and educational materials. The majority of the webinars will be a combination of a lecture on background material and a hands-on demonstration where participants will have the opportunity to use OpenTopography's tools to process and visualize topography data.

USGS 3DEP lidar covering areas impacted by Hurricane Ian now available from OpenTopography

Sep 30, 2022

In response to Hurricane Ian, OpenTopography is temporarily removing our academic user restriction on access to USGS 3D Elevation Project (3DEP) lidar datasets for impacted areas in Florida, Georgia, South Carolina, and North Carolina. We hope that OpenTopography's easy to use interface for accessing, processing, and visualizing high resolution USGS 3DEP lidar datasets in these affected regions will help to support hurricane emergency response, recovery and rebuilding, assessment of environmental impacts, and research.

New NCALM dataset in Nevada now available

Sep 28, 2022

A new lidar dataset covering 53 km² over the McLeod Springs Wash in Nevada is now available on OpenTopography. This lidar dataset was collected by the National Center for Airborne Laser Mapping (NCALM) as part of the Seed grant program for Michael Hasson at Stanford University. This dataset was collected to help analyze morphodynamics of an unvegetated meandering river.

New NCALM dataset over the South Padre Island, TX available

Sep 1, 2022

A new lidar dataset covering 61 km² over Padre Island, TX is now available on OpenTopography. This lidar dataset was collected by the National Center for Airborne Laser Mapping (NCALM) as part of the Seed grant program for Kenton Fisher at Texas A&M University. This dataset was collected to help analyze changes in the sand budget, elevation, and geomorphic facies of Padre Island.
