Three new lidar datasets collected by the National Center for Airborne Laser Mapping (NCALM) in California and Oregon are now available on OpenTopography. A repeat lidar dataset of Antelope Valley, CA covering approximately 24 km2 was collected by NCALM for Dr. William Dietrich at the University of California, Berkeley. The data were collected over Antelope Valley Ranch, ~60 km west of Yuba City, CA. Previous mapping of this area was completed in 2017, details of which can be found here.
The second NCALM lidar dataset released covers approximately 66 km2 northwest of Santa Barbara, CA and... more

Digital Terrain Model (DTM) and orthophotos are now available for the entire country of Haiti on OpenTopography. These datasets cover an area of approximately 29,239 km2, with raster and orthophoto resolution of 1.5 m and 0.25 m, respectively. These data were collected between 2014–2016 in a project led by Centre National de l'Information Géo-Spatiale (CNIGS) with funding from the World Bank. These data were accessed from HaitiData.org. OpenTopography is redistributing this data in order to aid the recovery and research efforts for the August 14, 2021 M 7.2 Haiti earthquake. We initially... more

OpenTopography is pleased to announce that we're now offering access to USGS 3D Elevation Program (3DEP) Standard Digital Elevation Models (DEMs) through our easy to use web-based interface with associated processing and visualization tools. USGS 3DEP DEMs are available at 1 arc-second (~30m), 1/3 arc-second (~10m), and 1-meter.
USGS 3DEP Standard DEMs represent the topographic surface of the earth and contain flattened water surfaces. Each DEM dataset is identified by its horizontal resolution and is produced to a consistent set of specifications. The elevations in these DEMs represent the... more

OpenTopography is pleased to announce the release of a new lidar dataset covering approximately 78 km2 near Hendersonville, North Carolina. This dataset was collected as part of an NCALM Seed grant for Dr. Corey Scheip at North Carolina State University to evaluate regional landslide area-volume scaling relationships after a large rainfall-triggered mass wasting event in western North Carolina. This project focused on how debris flows initiate, bulk, and deposit as a function of topographic variables. Data were collected by NCALM, an NSF-funded center that supports the use of airborne laser... more

ALOS World 3D - 30m (AW3D30) is a freely available, downsampled version of a high-resolution (5m) dataset collected by The Japan Aerospace Exploration Agency (JAXA). The ALOS World 3D - 30m dataset is a digital surface model derived from satellite-based stereo-photogrammetry. OpenTopography has updated its version of AW3D30 from version 1 (May 2015) to version 3.2 (January 2021). This new version is a vast improvement as it fills the null values in the older version with existing DEMs (see Table 1 in the documentation for details), and includes improved algorithms and processing techniques to... more
