A Portal to High-Resolution Topography Data and Tools
July 27 2012:
OpenTopography is pleased to announce the release of point cloud data for the Jemez Basin Critical Zone Observatory in New Mexico as well as an update to the Oregon Department of Geology and Mineral Industries Lidar Program dataset.
Jemez River Basin Critical Zone Observatory Data::
Under OpenTopography’s memorandum of understanding with the six NSF Critical Zone Observatories, we will be hosting all lidar data products collected to support research at the CZO sites. The CZOs are environmental laboratories established to study the chemical, physical and biological processes that shape the Earth’s surface, and thus lidar is one of several tools being utilized. The Jemez River Basin CZO includes Valles Caldera (upper part of the Jemez River basin) and Frijoles Canyon, New Mexico. The snow on and snow off datasets are being used to estimate snowpack, vegetation biomass and distribution, and bare earth elevations to help better understand and quantify ecosystem structure, geomorphology, and landscape processes within the Critical Zone Observatory.
Oregon Department of Geology and Mineral Industries Lidar Program Data:
This latest release of ongoing updates of the Oregon Department of Geology and Mineral Industries Lidar Program dataset includes lidar point cloud data of Portland, the Cascade volcano Mount Hood, the Northern Oregon Coast Range, the McKenzie River and the Cascade foothills. DOGAMI has been supervising and coordinating the collection of large swaths of high resolution, high accuracy lidar data in Oregon and adjacent states since 2006.
