New LINZ Datasets Now Available

Nov 16, 2023

Two new Land Information New Zealand (LINZ) datasets are now available through OpenTopography. These datasets are available through an ongoing collaboration between OpenTopography and LINZ that makes OpenTopography the primary distribution platform for point cloud data collected as part of the LINZ National Elevation Program. These datasets collectively add almost 4,800 km2 of high resolution topographic data over the Central Otago Region of the South Island (see areas in red in figure below).

Recent New and Updated LINZ Datasets

Nov 9, 2023

Over the past several months, OpenTopography has been working hard to add new datasets, and append more data to previously published projects over New Zealand. These datasets are available through an ongoing collaboration between OpenTopography and LINZ that makes OpenTopography the primary distribution platform for point cloud data collected as part of the LINZ National Elevation Program.

On-Demand Vertical Differencing of USGS 3DEP and NOAA Lidar Topography

Oct 25, 2023

OpenTopography has expanded our on-demand vertical differencing (a.k.a. topographic change detection) tools to the U.S. Geological Survey’s (USGS) 3D Elevation Program (3DEP) and the National Oceanic and Atmospheric Administration (NOAA) coastal lidar collections. This update makes it possible to use OpenTopography's tools to compute topographic change for more than 20% of the contiguous United States that are covered by more than one high resolution lidar topographic dataset.

New SfM Dataset over Mount Rainier, Washington

Sep 5, 2023

OpenTopography has recently added a new structure from motion (SfM) dataset over Mount Rainier in Washington State. This dataset was collected by the National Park Service Mount Rainier (MORA) Geology Division in cooperation with the Alaska Region Office (AKRO) in September 2021. This dataset provides a unique, high-resolution survey of the geology, glaciology and overall topography of Mt Rainier and its surrounding areas. Both the digital surface model and component orthophotos are available through OpenTopography.

Pima Association of Governments makes lidar data for Pima County open access on OpenTopography

Jul 10, 2023

Pima Association of Governments (PAG) has partnered with OpenTopography to make the most recent high-quality USGS 3DEP light detection and ranging (lidar) dataset over Pima County, Arizona “open access” via OpenTopography - an online, public, geospatial data portal. Lidar is a remote sensing method used to create high resolution three-dimensional representations of the Earth's surface, including buildings, streets, vegetation, and the ground.
