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
GPS Explorer - IGS AC Workshop - Miami 2008
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

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

GPS Explorer Web Demonstration
GPS Explorer - IGS AC Workshop - Miami 2008
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.

GPS Explorer Portal: INDIGO
SOPAC and INDIGO Utilize IT resources and JPL collaboration in support of
IGS
Potential development areas: Include all GNSS sites at CDDIS/JPL/IGN Extend GPS Explorer capabilities to include SLR/VLBI/DORIS
• Site mapping• Common data exploration/visualization tools
Global Seamless Archive Center (publication of data archive holdings)
• Incorporate GPS analysis products• Web services wrapper
GPS Explorer - IGS AC Workshop - Miami 2008
GPS Explorer Portal: Future
Focus on IGS support via INDIGO How can GPSE serve as common interface for user access to
data/metadata? Add “Products” tab Portal name change?
Evaluate/implement feedback from user survey, NASA website developers
Ingest/display new data sources
Cross-browser compatibility
Interactive Strain Maps
