GEON’s CI Contributions to Earthscope

EarthScope and GEON:

imageThe GEON project collaborates with EarthScope on a number of cyberinfrastructure projects, including development of the EarthScope Data Portal for distribution of EarthScope data, and use of the OpenTopography Portal for dissemination of GeoEarthScope LiDAR data. GEON is also developing the OpenEarth Framework (OEF) for integration of 3D and 4D earth science data. An alpha version of OEF has been used to visualize preliminary EarthScope data sets (see below).

The EarthScope Data Portal:

The EarthScope Data Portal ( was developed as a collaboration between the San Diego Supercomputer Center (SDSC), Incorporated Research Institutions for Seismology (IRIS), UNAVCO, and the International Continental Scientific Drilling Program (ICDP). The software architecture is based on technologies used in the GEON Portal (

The EarthScope Portal uses advanced cyberinfrastructure to provide a single point of access to EarthScope data from multiple data archives.

The Open Earth Framework (OEF) for integration of Earth Science data

GEON's Open Earth Framework (OEF) project is developing a new software architecture, toolkit, client applications, and web services to manage and visualize diverse multi-dimensional earth science data.

Red colors are S-wave model reduced velocity regions, which particularly highlight the sheet of reduced velocities in the upper 200 km across the Snake River Plain / Yellowstone region. Green colors are P-wave model increased velocity regions, which highlight the subducting Juan de Fuca slab and the newly discovered Great Basin Drip.

The OpenTopography Portal: Gateway to GeoEarthScope LiDAR data

The OpenTopography Portal ( is a GEON Project initiative to build an online system that provides integrated access to high resolution topographic data, web-based processing tools, and enables the user community to share knowledge, experiences and resources. The OpenTopography Portal incorporates the GEON LiDAR Workflow (GLW) system for LiDAR point cloud access and processing and adds mechanisms for access to standard digital elevation models (DEMs) and Google Earth-based visualizations.


OpenTopography hosts a variety of high-resolution LiDAR topography including data being delivered by the GeoEarthScope Project. Once complete, all GeoEarthScope LiDAR data for active faults throughout the western United States will be available through OpenTopography. For all GeoEarthScope data sets, LiDAR point cloud data, standard DEMs, and Google Earth hillshade visualizations will be available.

LiDAR data currently available via OpenTopography include: Southern San Andreas and San Jacinto faults (B4 Project), Northern San Andreas fault system (GeoEarthScope), Garlock fault (GeoEarthScope), and the Intermountain Seismic Belt (GeoEarthScope). More GeoEarthScope data will be added as it is delivered to OpenTopography.

NEW DATA: Yellowstone, Tetons, Wasatch

Released May 7th 2009: GeoEarthScope Intermountain Seismic Belt (ISB) LiDAR dataset 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 of the Wasatch fault
