OpenTopography is pleased to announce the release of twelve new datasets covering a range of landscapes and geologic features. These data were collected for a variety of scientific applications, and the release of these data is the product of recently signed memoranda of understanding (MOUs) between OpenTopography and the NSF National Center for Airborne Laser Mapping (NCALM), and the NSF Critical Zone Observatories (CZOs) respectively. These datasets are the first batch of many forthcoming releases of NCALM and CZO lidar data via OpenTopography.

Dear OpenTopography community,
Thank you for sharing our enthusiasm for high resolution topography! We hope that you are finding OpenTopography useful. As you know, the goal of OT is to be a portal to high-resolution topography data and related tools. Over the past two years we have quadrupled the amount of data we host, and are adding new data weekly. We've also established memoranda of understanding for data distribution with the NSF National Center for Airborne Laser Mapping, the NSF Critical Zone Observatories, the Tahoe Regional Planning Authority, and several other groups. We are also... more

As is the tradition, OpenTopography will be active at the upcoming American Geophysical Union fall meeting, December 5-9, 2011 in San Francisco. As we've done in the past, we'll have a booth in the exhibit hall and several scientific presentations that highlight the OpenTopography system and related research and development work.
Exhibit Hall
OpenTopography / NCALM Booth: This year we'll be sharing a double booth with our colleagues from the National Center for Airborne Laser Mapping, who are funded by NSF to collect airborne lidar data. With a shared booth, there will be one stop to learn... more

OpenTopography is pleased to announce the release of two new lidar point cloud datasets. Both datasets can be accessed via the OpenTopography "Find Data" interface.
Andrews Experimental Forest and Willamette National Forest LiDAR (Aug 2008):
Watershed Sciences, Inc. collected Light Detection and Ranging (LiDAR) data from HJ Andrews and the Willamette National Forest (NF) on August 10th and 11th 2008. Total area of the study is 17,705 acres. The total area of delivered LiDAR including 100m buffer is 19,493 acres. The dataset collection was funded by the National Science Foundation's Long-... more

A revised set of data products for the Lake Tahoe Basin lidar dataset are now available via OpenTopography. This updated release addresses specific issues related to lake level elevation in the hyro-enforced bare earth surface model. Specifically, the data vendor, Watershed Sciences, reprocessed the hydro-enforced surface so that "all lakes were lowered to the lowest identified shoreline elevation to ensure a constant elevation equal to the shoreline elevation. Elevations for rivers have been lowered where it was identified that the breaklines were slightly above the shoreline...Also... more

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.
On account of yesterday's southern California power outage, most OpenTopography systems are currently unavailable. The OpenTopography homepage: http://opentopography.org has been restored, but all data access, processing, and related services are currently down. We'll be working with San Diego Supercomputer Center IT support staff to bring servers up and restore full functionality as... more

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. The opentopography.org website should remain accessible throughout the downtime, but data access, processing, and other services will be unavailable.
Thank you for your patience. If you have... more

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:
Teton Conservation District, Wyoming Lidar
This dataset was collected during the summer of 2008 by Sanborn on behalf of the Teton Conservation District. The project mapped 141 square miles of area within the Snake River Range and the Teton National Forest. The area covered is west of the Snake River to the Bridger-Teton National Forest boundary, and from Teton Village to Red Top... more
