Acknowledgments
We would like to thank the Marine Corps
Warfighting Lab (MCWL), National Imagery and
Mapping Agency (NIMA), Defense Modeling and
Simulation Office (DMSO), and the Oceanographer
of the Navy (N096) for funding the development of
the Geospatial Information Database (GIDB).

Geospatial Information Database (GIDB)
  • Development began in 1994 and is ongoing
  • Object-oriented digital mapping database written
    in Smalltalk and stored in a GemStone OO database
    management system (ODBMS)
  • Capable of importing NIMAs VPF products and
    converting the data into an object format for
    display, query, and updating purposes
  • Capable of handling NIMAs RPF and TPS products,
    as well as multimedia (audio, video, GIF, JPEG).

Global Information Database System (GIDB)
  • Download Mission Specific Data Sets (MSDSs) from
    NIMA via SIPRNET converted to object format for
    use in Urban Warrior AWE
  • Supports near real time NIMA VPF object updates
    via SIPRNET
  • Upload Vector Product Format (VPF) objects with
    attribute information to SharedNet Object
    Instance Store (OIS) so mapping data is
    accessible by other IMMACCS Systems
  • Supports spatial queries from InCon EUTs

Geospatial Information Database (GIDB)
  • Accesses and displays NIMA products via a common
    object-oriented interface.
  • Provides automatic selection of available
    products including multimedia products like still
    photos, video clips, and audio based on your
    specified geographical area of interest.
  • Runs without special purpose software (Netscape
    4.5 browser is all that is required). CORBA
    compliant.
  • Creates custom map generation with user selected
    features via Netscape.
  • Views 3-D rendering and virtual touring with
    appropriate data.

9
Geospatial Information Database (GIDB)
  • Your Netscape 4.5 browser and the Internet is all
    you need to answer the key question, What
    information does NIMA have for this area of
    interest?

10
Geospatial Information Database (GIDB)
  • When the user specifies any Area of Interest
    (AOI) the GIDB will automatically check for all
    standard products, photos, audio, or video clips
    that relate to this geographical region and
    present a list to the user for selection. Note
    All information is coming from a single
    integrated database.

11
Geospatial Information Database (GIDB)
  • NIMA Vector Product Format (VPF), Raster Product
    Format (RPF) or Text Product Standard (TPS)
    products can be converted to a common
    object-oriented database structure. This allows
    the user to easily mix and match products to
    generate a display graphic that is uniquely
    suited to his needs.
  • Only VPF is implemented on the web currently
    other product types are under development.

12
Geospatial Information Database (GIDB)
  • With the appropriate data set, 3-D rendering and
    virtual touring is easily accomplished via use of
    the Netscape VMRL plug in, COSMO, available from
    cosmosoftware.com. This standard gives the user
    the low cost, power, and flexibility of commonly
    used internet packages.

Geospatial Information Database (GIDB)
  • GIDB can pass the AOI region description to
    commonly used web search engines like Yahoo to
    find other information available on the web
    related to the specified geographical area.

GIDB Top 10 Capabilities
  • Upload NIMA VPF Objects to Shared Net using CORBA
  • Spatial Query via Web browser and stand-alone
    mode
  • Internet/SIPRNET access with a conversational
    mode
  • Display and query VPF data by area of interest
  • Respond to spatial query for INCON client using
    CORBA

20
GIDB Top 10 Capabilities
  • Efficient/dynamic update of NIMA data as a local
    client or between GIDB systems via SIPRNET/
    Internet
  • Object-oriented to Relational VPF (VPF Export)
  • 3-D Rendering as an integrated function of the
    GIDB
  • Multimedia integration of audio, video, etc. into
    GIDB by AOI
  • Demonstration of Internet/ SIPRNET queries based
    on AOI

21
Conclusions for Vector Mapping/Air Community
  • Object Component Architecture Modular for Complex
    Problems
  • OO Approach supportive of Multi-Data
    Types/Integration
  • Could provide new capabilities in Updating/Battle
    Damage Assessment-type situations
  • Allows Querying to be driven to combat-level
  • Active Database benefits for on-the-fly
    visualization which could support human factors
    exploitation of display
  • Will allow advances in usage of Intelligent
    Agents to ease information overload
  • Could allow connection of any military asset to
    any level of data producer/command and control
    level
