C.3 DMAG Planned Activities for FY98

Results from a community-wide survey undertaken by the Boulder Facility at the end of FY97 identified the following high-priority software development activities for FY98:

  • Develop Ashtech receiver automated downloading/translating/data-logging software
  • Continue support for Trimble and TurboRogue receiver automated downloading/data-logging software
  • Provide systematic access to distributed archives (seamless archive concept)
  • Provide spatial and temporal map-based interface to the Archive
  • Continue support for TEQC, especially for translation to RINEX
  • Extend UNAVCO software support to additional platforms, e.g., HP-UX, DEC, SGI, Linux and Macintosh

Based on these software survey results and past recommendations of the UNAVCO Steering Committee and Working Groups, the prioritized activities for data management and archiving for FY98 are:

  1. Continued archiving of data from episodic GPS campaigns: FY98 will include complete archiving of data from 26 campaigns currently in the Physical Repository, 19 projects anticipated in 1997-1998 (Table C-2), as well as a portion of the 50 outstanding projects expected to arrive from principal investigators in this next fiscal year (Table C-3).
  2. Archiving of permanent station data: As previously discussed, a four-fold increase in permanent station data is expected in FY98 as continuous data are received from new NSF-supported permanent stations. As these stations are implemented, the Facility will work with the principal investigators to set up regular data transfers from the primary download and collection sites to ensure that these data are properly archived. Additional development will concentrate on design and development of electronic log sheets, improving and expanding receiver downloading and datalogging support, standardizing data transfer via LDM/IDD, automating the sorting and archiving of incoming data in the On-line Repository and Archive Database, and automating data file distribution to NSF researchers.
  3. Seamless Archive: Early in FY98 Scripps and the UNAVCO Boulder Facility will finalize the standards for metadata exchange and begin implementation of the "middle-ware" needed to extract the required information from their respective databases. Later in the year the specifications for making data requests will be developed and implementation started. The next step in the graphical Web User Interface tool development will be implementing a "smart" map that can be used to generate queries to the Archive Database. Using Java, the DMAG staff will add the capability to access in real-time, using a Web browser, metadata information such as monument name and time of occupation by clicking on a monument point on the map or timeline. The user will also be able to zoom-in on a selected region. The second phase development, to be initiated in late 1998, will use this click-and-zoom access to make queries of the Archive Database, providing a true GIS capability.
  4. Receiver download software: The development and support of software for automated receiver downloading from permanent stations, which was previously distributed throughout the Facility, is being consolidated in the DMAG for FY98. New developments will include support for Ashtech receivers downloading to UNIX platforms, in addition to refinements to the Trimble and Turborogue receiver software currently in beta-testing. Continued support to download software is critical to the robust and efficient operation of permanently installed GPS stations.
  5. TEQC: Enhancements will include: additional RINEX translators; improvements to the quality check, editing and graphics capabilities based on continuing community feedback and requirements; and support on a wide variety of UNIX, Linux, PC, and Macintosh platforms. TEQC will be further embedded into UNAVCO archive data ingestion and RINEX generation tools. User support will continue to an expanding user community.
  6. Archive infrastructure activities: Activities will include modifications needed to improve and further automate data handling, migrating use of electronic logsheets for use in campaigns, incorporating legacy orbit files and related data, scanning logsheets and site description files and records, incorporating new receiver data types, and writing and distributing data and metadata on CD-R media.
