CARIS Spatial Fusion

• A Web Serverto 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.

Wireless Access to Information
WAP (Wireless Application Protocol) is an open,
global specification that empowers mobile users
with wireless devices to easily access and
interact with information and services instantly.

Spatial Information and Wireless Access
Global System for Mobiles (GSM) - Public land
mobile network (9.6 Kbytes/sec)

• User point of View
• Data rates are too slow
• Connection setup takes too long
• Service is too expensive (charged when viewing
  web page)

• Technical point of View
• complete traffic channel is allocated for a
  single user for the entire call period.
• Internet traffic is bursty- inefficient resource
  utilization

12
Wireless Networks and Services

• General Packet Radio Service (GPRS)-bearer
  service for GSM that improves wireless access to
  packet data networks(100kbytes/sec).
• Universal Mobile Telephone System (UMTS) - future
  network (2 Mbytes/Sec)

The Concept
14
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.

15
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.

16
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

Summary

• Coastal and Marine Resources are important
• Information is important for decision making and
  (Good) Marine Governance
• Advances 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

18
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
