We are excited to announce a major expansion of OpenTopography's international data catalog with the addition of the High Resolution Digital Elevation Model (HRDEM) from Natural Resources Canada.
OpenTopography provides easy, centralized access to a diverse collection of topographic data. We strive to simplify data discovery by providing a single, accessible platform that integrates data from academic, private, and federal sources, including the USGS 3D Elevation Program (3DEP) and NOAA Coastal Lidar. Below are highlights of datasets that became available on the OpenTopography platform in June 2025.

Lidar systems produce a high density 'point cloud' - a collection of precise three-dimensional coordinates - that offers a detailed digital representation of scanned surfaces and their features. To unlock the full potential of this data for analysis, these points are classified after collection using algorithms and manual processing to differentiate surface types. This means each point is assigned a code identifying the type of feature it reflected from—such as ground, buildings, or vegetation.

The ongoing Los Angeles wildfires, including the Palisades, Eaton and Hurst fires, are scorching parts of the city and have destroyed thousands of homes and other buildings. On January 7, California Governor Gavin Newsom declared a state of emergency due to the fires.
In response to these devastating wildfires in southern California, OpenTopography is temporarily opening our services applied to all USGS 3D Elevation Project (3DEP) and NOAA Coastal lidar datasets covering Los Angeles County.
