Supporting Coastal and Marine Monitoring by Remotely Accessing Data Using Spatial Fusion and WAP A Conceptual Model Presenter : Sam Ng’ang’a Co-Presenter : Aldino Campos Value of Coastal and Marine Resources •Habitat for endangered species •Flood attenuation •Oil and gas •Water treatment •Tourism •Construction •Species breeding and resting areas •Groundwater recharge •Recreational and commercial fishing CoastGIS /Ng’ang’a, Campos, Sutherland, Nichols /2001 Governance VALUE SYSTEM Information Information Individuals Groups Organizations Individuals Rights Restrictions Responsibilities Groups Organizations Information ECONOMY Physical Environment SOCIETY POLITY Governance Is About Managing People’s Relationships With Each Other As They Interact With Their Environment (Sutherland, 2001) CoastGIS /Ng’ang’a, Campos, Sutherland, Nichols /2001 Importance of Spatial Information Allocation Regulation Spatial Information Adjudication Enforcement CoastGIS /Ng’ang’a, Campos, Sutherland, Nichols /2001 Spatial Information Paradigm Accurate Up-to-date Complete CoastGIS /Ng’ang’a, Campos, Sutherland, Nichols /2001 Thinner Fatter Thin Client Approach to Information Dissemination STAND ALONE PC CLIENT APPLICATION APPLICATION SERVER / DATA PROVIDER CLIENT APPLICATION APPLICATION SERVER CLIENT APPLICATION (BROWSER) 1 Tier WEB SERVER DATA PROVIDER APPLICATION SERVER DATA PROVIDER n Tier CoastGIS /Ng’ang’a, Campos, Sutherland, Nichols /2001 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. CoastGIS /Ng’ang’a, Campos, Sutherland, Nichols /2001 The Spatial Fusion User Interface CoastGIS /Ng’ang’a, Campos, Sutherland, Nichols /2001 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. www.wapforum.org •HTTP •WAP •Hyper Text Transfer Protocol •Wireless Application Protocol •Associated with the Internet (world wide web protocol) •Associated with the mobile phone network •Uses HTML •Uses WML CoastGIS /Ng’ang’a, Campos, Sutherland, Nichols /2001 HTML vs. WML <html> <head><title>TITLE HERE</title></head> <body> Hello World!

Internet traffic is bursty- inefficient resource utilization CoastGIS /Ng’ang’a, Campos, Sutherland, Nichols /2001 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) www.comsoc.org CoastGIS /Ng’ang’a, Campos, Sutherland, Nichols /2001 The Concept CoastGIS /Ng’ang’a, Campos, Sutherland, Nichols /2001 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. CoastGIS /Ng’ang’a, Campos, Sutherland, Nichols /2001 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. CoastGIS /Ng’ang’a, Campos, Sutherland, Nichols /2001 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 CoastGIS /Ng’ang’a, Campos, Sutherland, Nichols /2001 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 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 CoastGIS /Ng’ang’a, Campos, Sutherland, Nichols /2001 Acknowledgements This work is supported by the GEOIDE network Centers of Excellence Spatial Fusion™ is a product of Universal Systems Ltd of Fredericton, New Brunswick CoastGIS /Ng’ang’a, Campos, Sutherland, Nichols /2001
