GeoEarthScope Support
GeoEarthScope, a part of the EarthScope Program, includes the acquisition of aerial and satellite imagery and geochronology to examine the strain field beyond the decade time scales available from the PBO geodetic instrumentation. A goal of EarthScope is the improved understanding of the tectonic evolution of the North American continent. Identifying and understanding deformation rates in all tectonic regimes is critical to reaching that goal. UNAVCO provides support for EarthScope related imaging and geochronology activities.

News:
- [2008 Mar 28]
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. 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.
- GeoEarthScope InSAR data acquisition activities and updates are now available at http://geoes-insar.unavco.org/main.php.
- GeoEarthScope airborne LiDAR activities were featured in the Fall 2007 issue of the EarthScope onsite newsletter. Images from this article are available.
- GeoEarthScope airborne LiDAR data were successfully collected in northern California in Spring 2007. Over the course of several weeks approximately 1400 square kilometers of EarthScope targets were imaged, as well as supplementary targets for the USGS and the California PUC. 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 faults and structures. This represents a major milestone for GeoEarthScope and a significant achievement for the entire EarthScope project and community. More information is available here. Data are currently being processed by the National Center for Airborne Laser Mapping (NCALM), Ohio State University (OSU) and Arizona State University (ASU) and initial imagery products are expected to be released prior to the Fall AGU meeting.
- Twelve laboratories have been funded to provide GeoEarthScope geochronology services. These labs will provide services on the basis of available "credits" that will be made available to investigators identified by NSF via the merit review proposal process. A FAQ [PDF] has been prepared to address the most common questions raised by investigators interested in geochronology analyses for EarthScope.
