Two new review papers, co-authored by OpenTopography staff, have been published recently that focus on the use lidar and high resolution topography for understanding mass and energy transfer through landscapes and the critical zone respectively.
Analyzing high resolution topography for advancing the understanding of mass and energy transfer through landscapes: A review
Abstract:
The study of mass and energy transfer across landscapes has recently evolved to comprehensive considerations acknowledging the role of biota and humans as geomorphic agents, as well as the importance of small-scale... more

OpenTopography is pleased to announce the release of two new datasets in eastern California: the Poleta Folds and Surprise Valley. The Poleta Folds airborne lidar data were collected by Chris Larson of the University of Alaska Fairbanks. This dataset is particularly exciting because the area is a beautiful example of classic structural geology, where many universities teach undergraduate mapping courses. The Poleta Folds data were funded by Central Washington University, Caltech, University of Alaska, Fairbanks, Sacramento State University, University of California, Davis, Oregon State... more

OpenTopography is pleased to announce the release of high resolution point cloud data collected after the 2014 South Napa Earthquake. The August 24, 2014, South Napa earthquake (M6.0) produced significant damage resulting from shaking, fault rupture, fault afterslip, and ground deformation. Lidar data were collected to aid specialized work on the South Napa earthquake including: (1) fault afterslip, especially in the Browns Valley residential neighborhood; (2) shaking and correlation to damage such as red- and yellow-tagged structures, especially in the downtown Napa area; (3) seismic hazards... more

Over the next 2.5 weeks, OpenTopography will be participating in two short courses in Mexico - one at National Autonomous University of Mexico (Universidad Nacional Autonoma de Mexico), Mexico City, Mexico, and the other at CICESE (Centro de Investigacion Cientifica y de Educacion Superior de Ensenada), Ensenada, Baja.
The first short course, March 22-23, 2015 - Lidar Derived DEMs applied to Landslide, Fault, Earthquake Rupture, and Landscape Changes - is lead by OpenTopography and will be hosted by UNAM with support from CONACYT- INEGI. Agenda and course materials will be available online... more

OpenTopography is pleased to announce the release of three new datasets covering two volcanic fields in Northern Arizona and Nevada as well as a river confluence in Colorado. The Sunset Crater Volcanic National Monument data were funded by the National Parks Service and the Nevada and Colorado datasets were funded by the National Science Foundation and collected by the National Center for Airborne Laser Mapping (NCALM).
NCALM Data:
Both the Lunar Crater Volcanic field, NV and Colorado data were NSF projects collected by NCALM. NCALM is a NSF-funded center that supports the use of airborne... more

OpenTopography is pleased to announce the release of new point cloud data covering 3,684 km2 of most of the Salt Lake and Utah Valleys as well as the Wasatch and West Valley Fault Zones. These data are the result of a multi-organization effort to support flood mapping, geologic fault mapping, transportation, infrastructure, solar energy, and vegetation management projects. The state of Utah, including the Utah Automated Geographic Reference Center, Utah Geological Survey, and the Utah Division of Emergency Management, along with local and federal partners, including Salt Lake County and local... more

In October 2014, OpenTopography released lidar point cloud data and limited raster layers (bare earth, highest hit, intensity) for Sonoma County, CA. This week, new raster layers were added to the Sonoma County raster data in the OpenTopography portal. All raster layers now include: bare earth, hydro-flattened bare earth, highest hit, canopy density, and vegetation height as well as intensity layers for all returns, and vegetation.
From Sonoma County Vegetation Mapping & Lidar Program, "Sonoma Veg Map is a 5-year program to map Sonoma County's topography, physical and biotic features, and... more

Connect with OpenTopography at the 2014 American Geophysical Union meeting in San Francisco:
Visit our booth! OpenTopography will be in booth #2516 on "NSF Street" in the exhibit hall. The booth is shared with the National Center for Laser Mapping (NCALM). Our booth is staffed by OpenTopography staff and community members and is a great chance to ask questions, provide feedback, or discuss other topics.
This year we'll be holding OpenTopography Office Hours - a chance for OpenTopography users and community to ask specific questions on a topic of interest by connecting with the correct... more

OpenTopography is pleased to announce the release of lidar point cloud and raster data covering Sonoma County, CA. These data are a result of a five year effort to map Sonoma County's topography and physical and biotic features, and diverse plant communities and habitats (at a 1:5,000 or higher mapping). Several organizations including the University of Maryland, NASA, and the Sonoma Veg Map program funded the collection and hosting of data on OpenTopography.
From Sonoma Veg Map, "These foundational data sets are key to facilitating good planning and management for watershed protection,... more

OpenTopography is pleased to announce the release of two point cloud datasets covering areas of northern New Mexico and the Mojave desert in California. Both datasets were collected by the National Center for Airborne Laser Mapping (NCALM) in 2012. The data from New Mexico were collected under a National Science Foundation (NSF) award. The data from California were collected as part of NCALM's graduate student seed proposal program which awards ten projects per year to graduate student PIs who need lidar data for their research. NCALM is a NSF-funded center that supports the use of airborne... more
