GPS Explorer - IGS AC Workshop - Miami 2008 GPS Explorer Background n 5 -year NASA REASo. N project (GPS Data Products): deliver analysis products using newer IT standards n n n NASA ACCESS project (MOSES): users perform modeling via portlets n n 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 Apply various time series models (QOCA, RDAHMM) Extend to INDIGO: integration of multiple space geodetic techniques n n Leverage GPS Explorer technologies GNSS/VLBI/SLR/DORIS: provide uniform methods of data retrieval

GPS Explorer - IGS AC Workshop - Miami 2008 GPS Explorer Framework n Uses the n n n 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 n users select and save groups of GPS sites via mapping portlet. Data queries, modeling operations are performed on these in other tabbed pages. n Inter-portlet communication n Dynamic content produced via calls to back-end web services

GPS Explorer - IGS AC Workshop - Miami 2008 GPS Explorer Portal: Content n Mapping Interface n SOMI: Scripps Online Mapping Interface • University of Minnesota Map. Server; input data layers stored at SOPAC (e. g. , fault lines) • Draw bounding boxes to dynamically select sites • Recent performance boost - faster map loading n Migrating to Open. Layers • open source version of Google Maps n Processed GPS coordinates n n n 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 - IGS AC Workshop - Miami 2008 GPS Explorer Web Demonstration

GPS Explorer Portal: Geophysical Resource Web Services GPS Explorer - IGS AC Workshop - Miami 2008 n Standardized approach to data submission/retrieval n n Inter-agency data exchange of processing metadata, coordinates Use XML standards n Geography Markup Language (GML): represent features/geometry/reference systems/time • observation collections; filter encoding • transfer XML via SOAP/web services n Independent server-side code n n GPS Explorer is only a client Call web services from other web pages/sites, command-line utilities, etc.
