Title: The Concept of Smart Maps as Information Mediator in GeoNet 4D


1
The Concept of Smart Maps as Information Mediator
in GeoNet 4D
5th EC-GIS, Stresa
  • Gertraud Peinel Thomas Rose

2
Information Mediation
  • Information search, navigation, exploration,
    visualisation
  • COTS
  • Search Engines
  • Keyword based search
  • Hierarchical subjects
  • Problem
  • Boolean expressions
  • Guess subject of interest
  • Information exploration and encountering
  • Information Visualisation
  • Attributes of information (date, author,
    location,...)
  • Attributes of search results (ranking, number of
    keywords, access,...)
  • Latent Relations
  • temporal or spatial account
  • spatial relationships as one deduction source for
    information mediation

3
Objective
  • Use spatial account of information
  • Map based interface
  • Information related to named regions on map
  • Cartography
  • Figure showing an object of interest
  • Map signalises existence of referenced
    information
  • Categorization of information in hierarchical
    subjects
  • Meta data describing maps, regions, information
    sources, etc.
  • Views of information spaces
  • Smart Maps

4
Smart Maps
  • Sensitive Areas (also overlapping)

GeoNet 4D
  • EC ESPRIT programme 22223 (DG III)
  • July 1996 - September 1998
  • Application Focus
  • Ports and portuary zones
  • Application Domain
  • industrial site and facility management,
    emergency response
  • Objective
  • Smart maps for information mediation
  • Groupware functionalities
  • Prototype GeoPro

6
User Requirements
  • Virtual Organisation Ports and portuary zones
  • Actors
  • port authorities, maritime authorities,
    scientific organisations, pollution response
    organisations, emergency services, stevedooring
    companies, forwarders, shipping agents,
    territorial communities, customs, consultancies,
    meteo centres
  • Data Information
  • portuary infrastructure maps, marine charts, ship
    routing information, environmental data
    (including coastal zone characteristics, risk
    analysis, hazardous material data, as well as
    models and simulations, analysis results,
    monitored information, specific event data), port
    management information (time tagged vessel
    location data, arrival and departure dates, cargo
    types and tonnage), ship manifests, cargo details
    and customs information, legal and contractual
    documentation, social, economic and dynamic data
  • Information search, navigation, exploration,
    visualisation
  • Emergency response
  • Collaborative online information exchange on maps

7
Functionalities I
  • Visualization of maps/interaction with maps
  • Display of vector maps including Java drawings
  • Display and selection of different layers
  • Display of sensitive areas on mouse-over events
  • Zooming and panning
  • Display of longitudes and latitudes, zooming
    factor, size of drawings
  • Display of spatially related information
  • Popup-menus for the selection of categories and
    spatially related information
  • Launching of viewers for the visualisation or
    download of information (e.g., plug-ins, external
    viewers, HTML Windows)
  • Groupware
  • Creation, connecting to and closing of sessions
  • Joined editing (e.g. drawing on maps)
  • Exchange of messages (chat)

8
Functionalities II
  • Modification
  • Online modification of user projects (user
    specific collection of layers)
  • Online modification of layer colours and
    visibility of layers for projects
  • On-line map creation
  • Creation and deletion of projects
  • Creation, loading and storing of drawings (as
    Java drawings or in vector format)
  • Conversion of Java drawings in vector layers
  • Administration (server site)
  • General data population interfaces (including
    access to GIS functions like feature rendering)
  • Miscellaneous
  • Authentification (login)
  • Server APIs to call external functions, e.g.,
    bathymetry or animation tools

9
GeoPro Client
10
Markets and Application Scenarios
  • Facility Management
  • Collaborative or Concurrent Engineering
  • Corporate Portals
  • Kiosks

11
Accomplishments of GeoPro
  • Smart Maps
  • Information visualisation, exploration,
    confirmation
  • Search with image of location in mind, walking
    on maps
  • Graphical access by named regions
  • Ease of use
  • Inexperienced users, systems with no or
    uncomfortable keyboards
  • Views on information spaces
  • Maps - subjects - information sources
  • Various application domains
  • Cartographic maps, CAD, blue prints, photos
  • On top functions docked
  • Groupware
  • Bathymetry
  • Database population with little GIS knowledge

12
Spatial Perspective for KAM
  • most information have a temporal or spatial
    account
  • Derive spatial relationship - visualise spatial
    relationship
  • Intelligent assistance for geo-referencing and
    subject categorisation

13
Conclusion
  • Future Plans
  • Intelligent assistance for database population
  • Enhanced search capabilities
  • Search by text for information sources and for
    subjects
  • Selection of several regions
  • Animation
  • GPS, changes over time
  • Envision
  • Employing special GIS functions (neighbourhood,
    distance)
  • Foster market for GIS
  • Use of GIS for other knowledge asset management
    means
