Virtual Landscape - Application Scenario

• A crisis manager . . . sitting in a virtual 3D
  world
• . . .with all relevant information on a flooding
  event rivers, lakes, flooded areas, critical
  areas, support teams, logistic information, . . .
• . . . with graphical information about the status
  of resources (availability, current activity,
  etc.)
• . . . access to detailed information (magnifier,
  click)
• . . . alert function
• . . . colour coding for uncertain or outdated
  information (dark areas).
• . . . with direct communication to all players

Virtual Landscape - Approach

• Generate geometry from digital elevation model
• Add textures, as for example
• satellite image for coverage and illumination
• land use
• highlighting of areas
• Add vector data for streets, locations, region
  boundaries, etc
• Include interaction code, as for example
• zooming
• navigation
• pointing

Virtual Landscape - Technology

• Java3D as a platform independent library
• WebStart for automatic installation of client
• Spatial database as backend
