GPS Explorer Background
  • 5-year NASA REASoN project (GPS Data Products)
    deliver analysis products using newer IT
    standards
  • Portlet-based web portal web 2.0 (mapping,
    inter-portlet communication)
  • Develop/use standard formats (XML) and methods
    (web services) for improved metadata and data
    exchange
  • NASA ACCESS project (MOSES) users perform
    modeling via portlets
  • Apply various time series models (QOCA, RDAHMM)
  • Extend to INDIGO integration of multiple space
    geodetic techniques
  • Leverage GPS Explorer technologies
  • GNSS/VLBI/SLR/DORIS provide uniform methods of
    data retrieval

4
GPS Explorer Framework
  • Uses the
  • java-based windows in web portal with user
    controls can be used in other portal frameworks
    (JSR-168 standard)
  • user accounts save data/results for future
    viewing
  • Employs a workflow/dashboard approach
  • users select and save groups of GPS sites via
    mapping portlet. Data queries, modeling
    operations are performed on these in other tabbed
    pages.
  • Inter-portlet communication
  • Dynamic content produced via calls to back-end
    web services

5
GPS Explorer Portal Content
  • Mapping Interface
  • SOMI Scripps Online Mapping Interface
  • University of Minnesota MapServer input data
    layers stored at SOPAC (e.g., fault lines)
  • Draw bounding boxes to dynamically select sites
  • Recent performance boost - faster map loading
  • Migrating to OpenLayers
  • open source version of Google Maps
  • Processed GPS coordinates
  • millions of xyz coordinates from SOPAC/JPL/REASON
    combination/PBO combination
  • dynamically queryable and exportable to urls
  • GPS Time Series, Velocities, Strain Maps

6
  • GPS Explorer Web Demonstration

7
GPS Explorer Portal Geophysical Resource Web
Services
  • Standardized approach to data submission/retrieval
  • Inter-agency data exchange of processing
    metadata, coordinates
  • Use XML standards
  • Geography Markup Language (GML) represent
    features/geometry/reference systems/time
  • observation collections filter encoding
  • transfer XML via SOAP/web services
  • Independent server-side code
  • GPS Explorer is only a client
  • Call web services from other web pages/sites,
    command-line utilities, etc.
