3. 2006-06-01PGM Training - La Jolla, CA 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.

5. 2006-06-01PGM Training - La Jolla, CA 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. Overview Rationale

6. 2006-06-01PGM Training - La Jolla, CA 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. Overview Target Platforms

7. 2006-06-01PGM Training - La Jolla, CA oCampaign : Top-level container for a given campaign. oMonument : Geodetic monuments to be occupied by GPS during campaign. oObserver : Individuals performing field occupation component of campaign. oEquipment : Uniquely identifiable pieces of equipment (e.g. receivers, antennae) oSession : An electronic “field log” and much, much more. Associated with time-dependent information such as equipment, measurements, observed conditions, commentary, etc. oServer : The PGM project involves a common client-server relationship including a client (PGM Client) and a server (PGM Server). oMode : Primarily functional and authentication-oriented. oCampaign Download : Communication (over the internet) between a client and a server, whereby the entire “state” of a given campaign is loaded onto the client. oSession Upload : Communication (over the internet) between a client and a server, whereby a “completed” session is transferred to the server.
