LINZ dataset covering Queenstown, NZ now available
OpenTopography is pleased to announce the release of a new lidar dataset covering 166 square kilometers of Queenstown and Arrowtown on the South Island of New Zealand. The dataset, "Queenstown, Otago, New Zealand 2021" has an average point spacing of 7.8 pts/m2, and was funded by the Queenstown Lakes District Council , with data management by Toitū Te Whenua Land Information New Zealand (LINZ).
New NCALM dataset in North Carolina
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.

Updated ALOS World 3D DEM Now Available Through OpenTopography
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).
New global data available: NASADEM and Copernicus DEM
OpenTopography has expanded our collection of global datasets to include the NASADEM, as well as the European Space Agency (ESA) Copernicus Digital Elevation Models (DEMs). This adds to OpenTopography's existing global datasets: NASA Shuttle Radar Topography Mission (SRTM) DEM, STRM15+, and the Japan Aerospace Exploration Agency (JAXA) Advanced Land Observing Satellite (ALOS) DEM.
