UPDATE Sept 9, 12 pm: All OpenTopography systems should now be up. The visualization server may be intermittently unavailable due to residual networking issues caused by the Southern California power outage.
OpenTopography will be intermittently unavailable starting at 12 pm Pacific time on Thursday, September 8th, 2011. We will be physically relocating OpenTopography servers to a new rack location in the San Diego Supercomputer Center machine room. We anticipate certain components of OpenTopography to be unavailable during this migration and expect the outage to last several hours on Thursday afternoon.
UPDATE: The OpenTopography outage caused by loss of power on the UCSD campus has been resolved. Thanks for your patience.
On account of an unplanned power outage at the San Diego Supercomputer Center, certain OpenTopography services are down as of 4:45 pm Pacific on Friday August 5th. We are monitoring the situation and will restore OpenTopography services once power has been restored. Thank you for your patience.

NEWS RELEASE:
New Teton County, Wyoming LiDAR Data Available Online
OpenTopography is pleased to announce the release of four new lidar datasets. This release includes data from two airborne lidar surveys and a pair of terrestrial laser scanning (TLS) collections. The new datasets:
The OpenTopography team is pleased to announce the release of version 3.3 of the OpenTopography system. This release includes numerous user interface and system enhancements as well as bug fixes. The most prominent update in v 3.3 from the perspective of users and our data partners is that we've now made the "roles" of groups involved in a dataset collection more prominent.
We're pleased to formally announce the open source release of the OpenTopography-developed Points2Grid algorithm for Digital Elevation Models generation from lidar point cloud data. Points2Grid is a robust and scalable local gridding tool for processing LIDAR point cloud data to DEMs. The algorithm uses a local gridding method to compute grid cell elevation using a neighborhood defined around each cell based on a search radius provided by the user.
We are pleased to announce the release of v. 3.2 of the OpenTopography system. This is a major update that includes several new enhancements to the lidar point cloud processing system to add functionality, speed up processing, and to improve the user experience.
The 8th annual Cyberinfrastructure Summer Institute for Geoscientists (CSIG'11) will be held August 8th -12th, 2011, at the San Diego Supercomputer Center, University of California, San Diego.
