We are pleased to announce the availability of new EarthScope airborne LiDAR data products from Southern California and the Intermountain Seismic Belt (ISB):
Like the rest of the GeoEarthScope LiDAR dataset, these products are freely available from the OpenTopography portal at http://opentopography.org in the following formats:
We are pleased to announce the availability of new GeoEarthScope airborne LiDAR data products from the Intermountain Seismic Belt (ISB) project! This release includes high resolution LiDAR topography data collected in tectonically active regions of Utah and Wyoming, including Yellowstone and Grand Teton National Parks and the Nephi segment (southern strand) of the Wastach fault. These LiDAR data can be explored and downloaded in several ways:
Additional ISB LiDAR data products will become available in the coming months, including coverage of the northern strand of the Nephi Segment of the Wasatch Fault, as well as point cloud access and custom DEM generation capability for all ISB coverage using GEON developed cyberinfrastructure. A metadata document for this project is also currently in preparation.
We would like to thank the National Park Service, with special thanks to the Geology, GIS and fire cache personnel at Yellowstone and Grand Teton national parks, for their support and collaboration.
Data acquisition for the GeoEarthScope southern/eastern California airborne LiDAR project is scheduled to begin on March 31, 2008. Over the course of several weeks we plan to image more than 1200 square kilometers using high resolution airborne laser swath mapping (ALSM), as pioneered by the B4 LiDAR project that focused on the southern San Andreas and San Jacinto faults in 2005. A Google Earth KMZ file showing the planned flight zones is available here. Targets were identified by the GeoEarthScope LiDAR working group as led by Professor James Dolan at USC and other members of the community.
GeoEarthScope, managed at UNAVCO, is a component of the EarthScope Facility project that includes the acquisition of aerial and satellite imagery and geochronology. EarthScope is funded by the National Science Foundation (NSF) and conducted in partnership with the US Geological Survey (USGS) and NASA. This is the second major GeoEarthscope airborne LiDAR project to date, the first being the northern California LiDAR project flown in 2007. Additional GeoEarthScope airborne LiDAR projects planned for 2008 include targets in the Pacific Northwest, in the Intermountain Seismic Belt (including Yellowstone), and in Alaska.
LiDAR data will be collected and processed by the National Center for Airborne Laser Mapping (NCALM). Supplementary geodetic control and data analysis will be performed by Ohio State University. When data products become available they will be distributed by Arizona State University and the San Diego Super Computer facility. Hight rate GPS ground control data will primarily be collected by local continuously operating geodetic networks including PBO, NUCLEUS and SCIGN stations. Overall project management and GPS data collection is led by UNAVCO.
We are pleased to announce the latest public release of processed products from the GeoEarthScope Northern California Airborne LiDAR project! This release represents a substantial portion of the Northern California dataset. More data will be coming in the next few months, along with more advanced access and analysis tools.
The data are currently available as 1 km^2 tiles of 0.5 m digital elevation models - both unfiltered (all data) and filtered (bare earth) - in ESRI (ArcGIS) binary grid format.
There are now two ways to select the tiles: 1) We have built a new GoogleMaps-based interface accessible in the GEON Portal (see below), and 2) We have updated the KML for use in Google Earth (if you downloaded the first version, now is time to go back and get version 2.0). Both approaches allow users to browse the dataset extent, make selections, and then download tiles of interest. To get to the GoogleMaps or download the KML file, please go to the GEON web site and get a portal account (just takes a few minutes--http://www.geongrid.org--click on "Enter the GEON Portal" link at right and then select "Request an Account"). Once you have obtained a portal account, log in and navigate to "Tools" and then "GEON LiDAR". Choose the GeoEarthScope Northern California LiDAR Project (NoCAL). You will see the GoogleMaps interface. Zoom and navigate to the areas of interest and click on the tile of interest. Or, below the GoogleMap, you can download the KML. In addition, soon we expect to have the point cloud available for download and interactive DEM creation.
We have worked to make these data available as quickly as possible, so if you encounter problems please let Chris Crosby (chris.crosbyasu.edu) and Ramon Arrowsmith (ramon.arrowsmithasu.edu) know ASAP. Please also note that there is a forum in the GEON Portal dedicated to the GEON LiDAR data distribution and we encourage everyone to use it to post questions, ideas, solutions so that we can all share our discoveries.
The GeoEarthScope Northern California LiDAR project acquired high resolution airborne laser swath mapping (a.k.a. LiDAR) topography data in Spring 2007 along major active faults as part of the EarthScope Facility project funded by the National Science Foundation (NSF). Between this project and the previously conducted B4 project, also funded by NSF, the entire San Andreas fault system has now been imaged with high resolution airborne LiDAR, along with many other important geologic features. EarthScope is funded by NSF and conducted in partnership with the USGS and NASA. GeoEarthScope is a component of EarthScope that includes the acquisition of aerial and satellite imagery and geochronology.
