  3. OverviewGeneral PGM is a client-server architecture focused on streamlining and catalyzing GPS campaigns using a flexible, open source approach to development. Minimally, PGM dramatically reduces, if not eliminates entirely, the dependency on paper “log sheets” from GPS campaigns – taking users through a fully-documented and automated electronic process of “uploads” and “downloads” with a common host server for the campaign. Maximally, PGM offers unprecedented opportunities for on-the-fly leveraging of GPS campaigns, shaving countless hours of valuable time from a “typical” GPS survey while enabling processes and public accessibility sorely needed.

  4. OverviewPGM Hosted Campaigns PGM Training - La Jolla, CA

  5. OverviewRationale Expedite field-to-finish process by bypassing physical log sheets – removing transcription burden. Reduce ambiguities, errors of omission and commission. Improve fidelity of campaign information. Enhance operator-driven metadata generation and information collection using modern user interface with helpful conversions, calendars, choices and instructions. Modernize survey management using on-the-fly metadata submission and centralized (database-driven) project oversight by any number of parties or locations. PGM Training - La Jolla, CA

  6. OverviewTarget Platforms • Laptop/Desktop • Authorized (e.g. registered) parties involved in project can download, save, edit and upload project-related information from/to a central repository using PGM. • Personal Digital Assistant (PDA) • Same functionality, look and feel…different/smaller footprint. Internet connectivity required to “download” project templates and upload/submit work completed. Work-in-progress can be performed completely offline. PGM Training - La Jolla, CA

  7. OverviewGlossary • Campaign : Top-level container for a given campaign. • Monument : Geodetic monuments to be occupied by GPS during campaign. • Observer : Individuals performing field occupation component of campaign. • Equipment : Uniquely identifiable pieces of equipment (e.g. receivers, antennae) • Session : An electronic “field log” and much, much more. Associated with time-dependent information such as equipment, measurements, observed conditions, commentary, etc. • Server : The PGM project involves a common client-server relationship including a client (PGM Client) and a server (PGM Server). • Mode : Primarily functional and authentication-oriented. • Campaign Download : Communication (over the internet) between a client and a server, whereby the entire “state” of a given campaign is loaded onto the client. • Session Upload : Communication (over the internet) between a client and a server, whereby a “completed” session is transferred to the server.

  10. HighlightsEvent-Driven Workflow • on-the-fly quality control (ex. occupation completed, information uploaded, then GPS data file uploaded – PGM Server can detect when a GPS data file does not match the occupation it was associated with during the upload) • On-the-fly translation of raw GPS data files to RINEX format, and archival of both input and output in organized [publicly-accessible] directory structure • Development hooks for future connectivity with other systems, processes and behavior (ex. on-the-fly solution job submissions for each uploaded occupation) • Accessible interface (DBMS & server-side middleware) to enable parallel complimentary services such as • Mapping interfaces • Report generation PGM Training - La Jolla, CA

  11. HighlightsGUI-Based Client Software • Professional installers (desktop & PDA) • Compact framework w/ intuitive navigation and interaction PGM Training - La Jolla, CA

  12. HighlightsServer-Side Development Platform Includes a versatile server component amenable to rapid development, customization and broader “institutional” use for other purposes. PGM Training - La Jolla, CA

  13. HighlightsEvolving System of Logic Entire strategy (“PGM”) intended to catalyze rapid development and progression of geodetic IT systems, through an engagement with extensive pool of community experts, field-savvy professionals and developers. Input from community can be quickly assessed, dealt with and fit into the PGM system to benefit everyone. PGM Training - La Jolla, CA

  14. DevelopmentTechnologies – PGM Client Javausing combination of open source IBM Eclipse development platform and licensed IBM WebSphere Application Developer. XML using oXygen XML editor for schema & instance development and validation (an Eclipse plugin). PGM Training - La Jolla, CA

  15. DevelopmentTechnologies – PGM Server Perlusing combination of custom middleware, system utilities and CGI interfaces with open source modules from CPAN, XML parsing libraries from Apache, online service connectivity to the NGS (ex. datasheets, geoid calculations), and GPS shareware like teqc from Unavco, Inc. PGM Training - La Jolla, CA

  16. DevelopmentPeople PGM development has involved significant changes to the way the CSRC conducts IT operations. From relational database schemas, to GPS data file management, website development, XML schema modeling, standalone application development – PGM has already made a significant, positive, impact on the CSRC.
