OpenTopography is pleased to announce the release of a new lidar dataset covering about 65 km2 within New Zealand's North Island. Data were collected in November 2016, and the survey area includes the northern coastline of Whangarei Harbour.
OpenTopography is pleased to announce the release of a new lidar dataset covering about 145 km2 within New Zealand's North Island. Data were collected between February 2017 and April 2019, and the survey area includes the Thames Township and the surrounding area.
OpenTopography is pleased to announce the release of a new lidar dataset covering about 485 km2 within New Zealand's North Island. Data were collected in April 2019, and the survey area includes Reporoa Township and the surrounding area as well as the Upper Piako River catchment.
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.
