OpenTopography invites you to join us for a one hour live webinar on Monday January 11 at 2-3 EST/11-12 PST on topographic differencing. Learn about vertical and 3D topographic differencing and perform differencing on OpenTopography's web interface with one of 60 datasets pairs with differencing enabled.
Over the past two years, OpenTopography has released several on-demand differencing tools for performing change detection of multitemporal datasets. With these tools, users can measure landscape change from natural and anthropogenic processes including urban growth, vegetation change, river... more

A new Structure from Motion (SfM) dataset comprising well georeferenced, high-resolution topography and orthomosaics for part of the Lost River fault zone, Idaho has been released. The dataset was collected by Dr. Michael Bunds and Christopher DuRoss from May 2015 - May 2016 and covers ~6.1 km of surface rupture from the 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. This dataset compliments the Lost River Fault Zone Near Borah Peak, Idaho... more

OpenTopography is pleased to announce the release of a new lidar dataset covering approximately 230 km2 covering Cedar Mesa and Bears Ears National Monument, Utah (Shash Jáa Unit). This dataset was collected for a study to explore the dynamic impacts of environmental change and biomass harvesting on woodland ecosystems and traditional livelihoods. Data was collected by NCALM, an NSF-funded center that supports the use of airborne laser mapping technology (a.k.a. lidar) in the scientific community and is jointly operated by the Department of Civil & Environmental Engineering, Cullen... more

OpenTopography is pleased to release a structure-from-motion small Uncrewed Aerial System (sUAS) dataset that covers 3 km2 along the creeping section of the central San Andreas fault. This dataset was collected in October 2017 by Michael Bunds and Nathan Toke from Utah Valley University, Chelsea Scott from Arizona State University, and several undergraduate students in Utah Valley University’s Geospatial Field Methods course. This dataset was collected to perform topographic differencing with the 2007 EarthScope Northern California airborne lidar dataset.

OpenTopography is pleased to announce the release of two new NCALM lidar datasets. The first is an NCALM Seed Dataset collected for Nate Mitchell at Indiana University, Bloomington. These data were used in a study to measure variations in bedrock cliff morphologies along Boulder Creek, northwest of Salmon, Idaho. The second dataset covers a 2013 landslide adjacent to Salsipuedes Bay, in Baja California, Mexico as well as Punta Morro, where Ensenada's science cluster is located, hosting the campuses of CICESE, UNAM and UABC. These datasets were collected by NCALM, an NSF-funded center that... more
