Enhanced Access to NASA Heterogeneous Geodetic Imaging Products through GeoGateway Analysis, Modeling, and Response Tools

Principal Investigator: Andrea Donnellan, NASA's Jet Propulsion Laboratory (JPL)

GeoGateway is a web map-based science gateway that expands the utility of NASA’s geodetic imaging data. GeoGateway provides tools for scientific discovery, field use, and disaster response using Interferometric SAR (InSAR) and Global Positioning Systems (GPS) integrated with earthquake faults data sets, seismicity data, and models. The goal is to expand the utility of NASA geodetic data sets by making the data easy to access, analyze, and interpret.

Under this ACCESS award, Andrea Donnelan’s team at JPL developed the capability to analyze and rate products. Feature detection tools were developed for estimating slip on fault and for analyzing time dependent geodetic data.

The goal of this ACCESS 15 project was to bring GeoGateway to an operational level of maturity. Objectives included:

  • Simplify the discovery of geodetic imaging products
  • Enable users to explore and integrate data through online or offline analysis
  • Allow researchers to easily share, publish, and collaborate on results of these online experiments
  • User annotation and notecards
  • Data quality metrics
  • Support of automated feature detection
  • Incorporation of optical data products
  • Support for Unmanned Aerial Vehicle Synthetic Aperture Radar (UAVSAR) and, eventually, the joint NASA-ISRO SAR Mission (NISAR).

GeoGateway tools were used to analyze the 2018 Montecito Debris flows following the Thomas fire near Santa Barbara, California and to relate post-seismic slip associated with the 2010 M7.2 El Mayor-Cucapah earthquake to fault friction laws. More recently, UAVSAR products were published for Southern California’s Woolsey Fire. Products posted on GeoGateway are used by the US Geological Survey and the State of California as well as by academic researchers.
