OpenTopography is pleased to announce the release of three new datasets covering areas of California, and Mexico. Two of the three datasets were collected as part of NCALM's seed grant program. NCALM is an NSF-funded center that supports the use of airborne laser mapping technology (a.k.a.
OpenTopography is pleased to announce the release of a high-resolution topographic data set and orthomosaic that cover ~ 5 km of the House Range fault and shoreline features of late Pleistocene Lake Bonneville in the Sevier Desert, eastern Basin and Range, Utah, USA. The House Range fault (HRF) is a range-bounding, west-dipping normal fault in the western Sevier Desert, within the Basin and Range province.
OpenTopography is pleased to announce the release of high-resolution topography and orthomosaics of part of the Lost River fault zone (LFRZ), Idaho. The data set covers the northern ~16 km of the surface-rupture that occurred on the LRFZ in the Mw 6.9 1983 Borah Peak Earthquake. Point clouds and digital surface models (DSMs), were generated from low-altitude aerial photographs using Structure-from-Motion and multi-view stereo processing (SfM). The LRFZ is a major, range-bounding, west-dipping normal fault in the northern Basin and Range province.
After a big earthquake happens people ask, ‘Where did the earthquake occur? How big was it? What type of fault was activated.’ We have designed an undergraduate laboratory exercise where students learn how geologists and geodesists use airborne lidar topography data to answer these questions for a synthetic earthquake along the Wasatch Fault in Salt Lake City, Utah. Students use high resolution topography data to measure how much and in what direction the ground moved during the earthquake.
OpenTopography is pleased to announce the release of six new datasets covering areas of California, Idaho, Washington, and Mexico. Four of the six datasets were collected as part of NCALM's seed grant program. NCALM is an NSF-funded center that supports the use of airborne laser mapping technology (a.k.a.
OpenTopography will be attending the Arizona Geographic Information Council (AGIC) meeting in Prescott, AZ from October 1 - 4 2019. Members of the OpenTopography will be staffing a booth, so please come by and say hello - it is a great chance to ask questions, provide feedback, or to discuss lidar, high resolution topography, and cyberinfrastructure.
Thanks to a collaboration with the Kaibab National Forest (U.S. Forest Service), OpenTopography is pleased to announce the release of high-resolution topography and forestry dataset over the Kaibab Plateau in Arizona. The purpose of this acquisition was to provide lidar data for portions of the Kaibab National Forest and Grand Canyon National Park on the Kaibab Plateau, in support of ongoing studies of Northern Goshawk demographics. Data were collected in summer 2012 and cover over 1800 km2 of the plateau with an average point density of more the 15 pt/m2.
OpenTopography is pleased to announce the release of a new lidar dataset covering about 700 km2 of New Zealand's Marlborough region of the South Island. Data were collected during summer of 2018 and includes coverage of the cities of Picton and Blenheim.
OpenTopography is happy to co-sponsor and co-organize this exciting workshop September 30 to October 4, 2019 in Potsdam, Germany. Thanks to support from our NSF EarthCube A^2HRT RCN, we will provide travel support for up to five early career participants from the US.
Description:
OpenTopography is pleased to announce the release of digital surface model (DSM) that is a mosaic of 2 meter resolution stereogrammetric DSMs acquired prior to the July 2019 Ridgecrest, California earthquake sequence. This dataset covers over 10,000 km 2 of the region surrounding the recent earthquakes, and provides a unique opportunity for research of this event. This is a pre-release of a larger data set of California (CaliDEM) that will be fully submitted to OpenTopography at a later date.
