CARIS Spatial Fusion™ A Web Server:to serve the data access web pages Orbix™ Runtime: lets the Spatial Fusion applet and the
Data Services communicate across the Internet. Catalog Service: This service lists all of the available
Fusion Data Services. Fusion Data Services: registered with the OrbixWeb™
Implementation Repository and containing configuration files (data service name and location).
Configuration Utilities: CARIS MapSmith™ and CARIS dbMaps™ - customize the display of CARIS, Oracle 8i Spatial, or Shapefile data.

Spatial Information and Wireless Access
User point of ViewData rates are too slowConnection setup
takes too longService is too
expensive (charged when viewing web page)
Technical point of Viewcomplete traffic
channel is allocated for a single user for the entire call period.
Internet traffic is bursty- inefficient resource utilization

Similar Applications
The AVL (Automatic Vehicle Locator) Service lets Spatial Fusion track vehicles in real time.
The AVL Service currently works with Sierra Wireless Modems. The GPS information is received via Trimble ASCII Interface Protocol.

Similar Applications
Researchers at UNB Computer Science Department have successfully investigated the use of the Wireless Application Protocol (WAP) to make it possible for Internet clients to access, display and save real-time geospatial information of a mobile agent in a working field.

Similar Applications
The research utilises Wireless Application Protocol (WAP) along with eXtensible Markup Language (XML) tags.
We invite you to visit the GEOIDE conference at The Lord Beaverbrook, Fredericton, New Brunswick on 21st and 22nd June 2001 for more information

SummaryCoastal and Marine Resources are importantInformation is important for decision making and
(Good) Marine GovernanceAdvances in WAP technologies indicate that it is
possible to wirelessly disemminate marine information
The Thin Client Microbrowser found on mobile devices is “close” to the Spatial Fusion™ Web Mapping Solution
CoastGIS /Ng’ang’a, Campos, Sutherland, Nichols /2001
Summary
Spatial Fusion™ Infrastructure is being used for wired and wireless retrieval of information
3G wireless access will allow wireless retrieval and dissemination of “broadband” information.
Research is needed to (further) fuse the web-mapping and WAP technologies together
