Congratulations to Emily Kleber, a Geospatial Data Specialist for OpenTopography, on receiving a National Science Foundation (NSF) East Asia and Pacific Summer Institutes (EAPSI) Fellowship to study earthquakes in Japan this summer. In addition to her graduate work at ASU with OpenTopography Co-I Ramon Arrowsmith, Emily supports several OpenTopography activities including data ingestion, user support, and educational content development. Previous to starting her graduate work at ASU, Emily worked full time at the San Diego Supercomputer Center where OpenTopography is based.

The Shuttle Radar Topography Mission (SRTM) obtained 90 meter (3 arc-second) resolution data on a near-global scale (between 56 degrees South and 60 degrees North latitude) and 30 meter (1 arc-second) resolution over United States, providing a valuable global topographic dataset. The SRTM data were collected during an 11-day mission in February of 2000 from a radar system onboard the Space Shuttle Endeavor. The SRTM project was led by the National Geospatial-Intelligence Agency (NGA) and NASA.
OpenTopography is now hosting version 3.0 (SRTM Plus) of the SRTM dataset released in November... more

OpenTopography has received a Windows Azure for Research Award from Microsoft Research. The Windows Azure for Research program "facilitates and accelerates scholarly and scientific research by enabling researchers to use the power of Windows Azure to perform big data computations in the cloud".
The award grants OpenTopography a one-year allocation of Windows Azure cloud resources, which we plan to use to evaluate distributed, on-demand, scalable compute infrastructure solutions for processing data from the OpenTopography facility's growing archive. We will start by deploying IaaS (... more

OpenTopography recently released five new point cloud datasets collected over parts of the Big Island and Kauai in Hawaii. These datasets were collected in 2013 by the National Center for Airborne Laser Mapping (NCALM). NCALM is a 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 College of Engineering, University of Houston and the Department of Earth and Planetary Science, University of California, Berkeley. These two datasets were... more

On account of the winter holiday break and San Diego Supercomputer Center and University of California, San Diego closures, OpenTopography will be providing reduced support between December 21st and January 1st. OpenTopography systems will be fully available and users may run jobs as they normally do. However, responses to email, system outages, and bug reports may be delayed. If you have questions or concerns please email info@opentopography.org and we will get back to you as soon as possible. Thanks for your patience and happy holidays from the OpenTopography Team!

OpenTopography is pleased to announce the release of three new datasets covering areas of California, Colorado and Florida. These datasets were collected by the National Center for Airborne Laser Mapping (NCALM) during 2010 - 2012 campaigns. NCALM is a 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 College of Engineering, University of Houston and the Department of Earth and Planetary Science, University of California, Berkeley.... more

OpenTopography is pleased to announce the release of almost 50,000 square kilometers of point cloud and raster data covering the state of Indiana. The recently released Indiana 2011-2013 Statewide Lidar represents a joint effort to make statewide data available by several Indiana state and federal agencies as well as private companies and individuals through a service agreement with OpenTopography. The robust cyberinfrastructure and user-friendly interface of OpenTopography provide a one stop shop for the statewide survey data catering to a variety of users requiring a range of lidar... more

OpenTopography is guided by an advisory committee which represents OpenTopography users and partners and provides valuable input on decisions related to OpenTopography priorities for data ingestion, interoperability relationships, algorithm and tool deployment, collaborations, and education and community engagement. We seek a graduate student (M.S. or Ph.D.) to join the advisory committee and represent the interests of young scientists who interact with OpenTopography. Responsibilities are participation in one face-to-face advisory committee meeting per year plus occasional conference calls.... more
