We will provide access to GPS, InSAR, and Uninhabited Aerial Vehicle Synthetic Aperture Radar (UAVSAR) geodetic imaging observations through a web- enabled map-based data product search and analysis gateway (GeoGateway). GeoGateway will provide users the ability to customize search and download of geodetic imaging products through an intuitive map interface and interactively perform analysis with capability for further offline analysis. This project utilizes mature QuakeSim and E-DECIDER map-based data and analysis tools to enable users to efficiently find, understand, and interact with multiple heterogeneous NASA Earth science data sets through a mobile- and desktop-compatible Web interface. The objective is to make NASA data readily and intuitively available to science and applications users, including non-experts in GPS and InSAR/UAVSAR observations. End users include disaster response and hazard scientists.

We will integrate and deploy existing QuakeSim tools that are built on the Open Geospatial Consortium compliant GeoServer and the E-DECIDER geographic information system and mobile device location awareness tools. Specifically users will be able to:

  • select a region of interest,
  • view available heterogeneous data products including UAVSAR, InSAR, GPS, and earthquake faults,
  • turn layers of interest on and off, 4) change color mapping of the InSAR/UAVSAR observations for more intuitive understanding of a particular product,
  • display in graph form selected segments of the data products, including GPS time series and UAVSAR line of sight ground range change,
  • download customized sets of data products, and
  • view the observations on a mobile device with location awareness for field application and upload relevant images back to the data system.

GeoGateway will be used for scientific discovery as well as field and disaster response applications by providing data overlay and visualization, interactive analysis features, and data product download. The non-interactive backend data processing is carried out through the GeoServer infrastructure to support Web Processing Service (WPS) workflow standards with related provenance support. The system will be robust and reusable, with open source development that allows for maintainability and extension of the application. We will provide for the addition of new data sources and analysis tools into the map interface framework through open standards and APIs. Additionally, other institutions can adopt and deploy the tools either as an iframe in a browser, using representational state transfer (REST) interfaces, or by using the source code.
