New lidar datasets available: Kern Canyon and Lake Isabella, CA

Dec 9, 2019

OpenTopography is pleased to announce the release of a new lidar dataset covering about 439 km² along Kern Canyon, CA. The dataset was collected in 2008 for the Army Corps of Engineers and was used to identify late Quaternary deformation, and other seismogenic processes that are occurring in this region of the Sierra Nevada mountain range. These data were also used for analysis and mapping of floodplains along the Kern River.

OpenTopography at the 2019 American Geophysical Union Meeting

Dec 7, 2019

Connect with OpenTopography at the 2019 American Geophysical Union meeting in San Francisco, CA! OpenTopography will be in booth #311 on "NSF Street" in the exhibit hall. The booth is shared with the National Center for Airborne Laser Mapping (NCALM). Our booth is staffed by the OpenTopography team and community members, and is a great chance to ask questions, provide feedback, or to discuss lidar, high resolution topography, and cyberinfrastructure.

Three new NCALM datasets released from California, and Mexico

Nov 13, 2019

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.

New SfM photogrammetry dataset covering parts of the House Range Fault in Utah

Oct 18, 2019

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.

New SfM photogrammetry dataset covering parts of the Lost River Fault Zone in Idaho

Sep 23, 2019

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.

Undergraduate Topographic Differencing Exercise

Sep 22, 2019

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.

Six new NCALM datasets released from California, Idaho, Washington, and Mexico

Sep 18, 2019

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.
