Tools / Applications

Here, “tools” refers to a set of packaged “applications” that may include datasets, modeling and analysis codes, and mapping and visualization software, which together serve a specific science needs. These tools can be found in the Portal. Currently, the set of tools includes:

• SYNSEIS: a synthetic seismogram computation toolkit that allows users to calculate synthetic 3D regional seismic waveforms using a robust finite difference code, E3D, developed by the Lawrence Livermore National Laboratory. SYNSEIS is built as a grid application and accesses distributed data centers, e.g. the IRIS data center, and large computational clusters, e.g. supercomputing platforms in the TeraGrid.
  
  
• GEON LiDAR Workflow (GLW): provides an end-to-end system for the distribution and processing (DEM generation) of LiDAR / ALSM point cloud data. Currently, this application provides online access to 4 different LiDAR point cloud data sets that account for over 6 billion data points.

Data sets served by GLW were acquired by a several different agencies and researchers including, (i) the U.S. Geological Survey (USGS ) and the National Aeronautics and Space Administration (NASA), with funding provided by NASA's Earth Surface and Interior Focus Area. These data were acquired and processed by TerraPoint, LLC under contract to NASA's Stennis Space Center. (ii) The National Center for Airborne Laser Mapping (NCALM), on behalf of Dr. Mike Oskin (University of North Carolina) and Dr. Lesley Perg (University of Michigan), as part of their NSF project on fault systems in the Eastern California Shear Zone. They have agreed to make these data available to the research community through GEON. (iii) NCALM, through funding from the National Science Foundation (NSF) as part of the "B4 Project". The B4 Project has agreed to make these data available to the research community through GEON.

• The PaleoIntegration Project: provides access to five global-scale databases, comprising sedimentary rocks, dinosaurs and fossil plants, as well as to tools for computing paleo latitude and longitude.

The data includes (i) PGAP Lithofacies and Climate Sensitive Sediment data compiled by Fred Ziegler, David Rowley, and other members of the Paleogeographic Atlas Project, (ii) Oil Source Rock data courtesy of Judy Parrish, (iii) Dinosaur data from The Dinosauria (Weishampel et al., 2004), (iv) Fossil plant data from the Paleobiology Database, and (v) Paleomaps and plate rotation program provided by Chris Scotese, to enable paleocoordinate calculations.

Each database can be searched individually or in any combination with the others, via text or interactive maps. The results can be plotted on paleomaps, using the paleocoordinate computation tool.

• Gravity and Magnetic Data Repository System: a compilation of gravity and magnetic data for the Southwestern US. The Pan American Center for Earth and Environmental Studies (PACES) and GEON played a significant role in the compilation of gravity data in southwestern North America. This effort has been conducted in close cooperation with the U. S. Geological Survey, the National Image and Mapping Agency, NOAA, and academic colleagues.
