OpenTopography recently released our first near-global satellite dataset as well as 20 new Google Earth files. The Shuttle Radar Topography Mission (SRTM) is a near-global 90 meter resolution raster dataset. New Google Earth lidar imagery files are for lidar datasets collected by the National Center for Airborne Laser Mapping (NCALM) between 2003 and 2007..
The US Geological Survey recently discontinued delivering LiDAR data through the CLICK (Center for LiDAR Information Coordination and Knowledge) interface. While CLICK was active, the OpenTopography Find Data page provided users the ability to discover and easily access LiDAR data available from the USGS archive. Now that CLICK is no longer active, OpenTopography has removed this functionality from our site.
OpenTopography is pleased to announce that we've completed our work to ingest and provide open access to all National Science Foundation funded lidar datasets collected by the National Center for Airborne Laser Mapping (NCALM) between 2003 - 2012. In total, there are now 116 NCALM point cloud lidar datasets available via OpenTopography - greater than 126 billion lidar points over more than 22,000 km2 of North America.
OpenTopography recently released five new point cloud datasets collected over areas of Owens Valley (CA), the Colorado Rockies, Mt. Rainier National Park (WA) and Yellowstone National Park (WY). These datasets were collected in 2010 and 2012 by the National Center for Airborne Laser Mapping (NCALM). NCALM is a NSF-funded center that supports the use of airborne laser mapping technology (a.k.a.
OpenTopography is pleased to announce the release of point cloud and raster data supporting ongoing seismic hazard research surrounding the Diablo Canyon Power Plant, Central Coast California. The datasets were provided by Pacific Gas & Electric Company (PG&E) and are comprised of three separate surveys: Diablo Canyon (2010), Los Osos (2011), and San Simeon (2013).
Eight datasets from six states were recently released by OpenTopography covering areas of California, Maine, New Mexico, North Carolina, Pennsylvania and Utah. These data include four Critical Zone Observatory (CZO) datasets, three National Center for Airborne Laser Mapping (NCALM) datasets and one dataset from the Utah Geological Survey.
OpenTopography will be at the 2013 European Geosciences Union (EGU) Meeting this week in Vienna, Austria:
OpenTopography has released ten datasets covering a small area in Brazil as well as the US states of Alaska, California, Montana, North Carolina and Oregon. These data cover a diverse range of topographic environments and were collected to study active tectonics, volcanic areas, coastal geomorphology and hydrology.
OpenTopography is a partner on a recently awarded National Science Foundation grant to develop software tools to make it easier for scientists to analyze lidar point cloud data.
Four datasets covering areas of Northern Vermont, Mojave Desert, Northern California Coast Range, and Southern New Hampshire are now available through OpenTopography.
