Overview General 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. 2006 -06 -01 PGM Training - La Jolla, CA
Overview PGM Hosted Campaigns 2006 -06 -01 PGM Training - La Jolla, CA
Overview Rationale 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. 2006 -06 -01 PGM Training - La Jolla, CA
Overview Target 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-inprogress can be performed completely offline. 2006 -06 -01 PGM Training - La Jolla, CA
Overview Glossary o Campaign : Top-level container for a given campaign. o Monument : Geodetic monuments to be occupied by GPS during campaign. o Observer : Individuals performing field occupation component of campaign. o Equipment : Uniquely identifiable pieces of equipment (e. g. receivers, antennae) o Session : An electronic “field log” and much, much more. Associated with time-dependent information such as equipment, measurements, observed conditions, commentary, etc. o Server : The PGM project involves a common client-server relationship including a client (PGM Client) and a server (PGM Server). o Mode : Primarily functional and authentication-oriented. o 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. o Session Upload : Communication (over the internet) between a client and a server, whereby a “completed” session is transferred to the server. 2006 -06 -01 PGM Training - La Jolla, CA

Highlights General • • Event-Driven Workflow GUI-Based Client Software Server-Side Development Platform Evolving System of Logic 2006 -06 -01 PGM Training - La Jolla, CA
Highlights Event-Driven Workflow o 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) o 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 o Development hooks for future connectivity with other systems, processes and behavior (ex. on-the-fly solution job submissions for each uploaded occupation) o Accessible interface (DBMS & server-side middleware) to enable parallel complimentary services such as o Mapping interfaces o Report generation 2006 -06 -01 PGM Training - La Jolla, CA
Highlights GUI-Based Client Software o Professional installers (desktop & PDA) o Compact framework w/ intuitive navigation and interaction 2006 -06 -01 PGM Training - La Jolla, CA
Highlights Server-Side Development Platform Includes a versatile server component amenable to rapid development, customization and broader “institutional” use for other purposes. 2006 -06 -01 PGM Training - La Jolla, CA
Highlights Evolving 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. 2006 -06 -01 PGM Training - La Jolla, CA
