  • Virtual tourism & travel planning
  • Education: geographical & general reference
  • Planning: land planning / land usage, urban planning
  • Civil engineering, telecommunications, utilities, and other infrastructure
  • Visualization of weather and other environmental attributes
  • Real Estate
  • Diplomacy
  • Games and entertainment
  • Communications: radio/TV/cellular transmitter placement and signal analysis
  • Public participation in land management
  • The Israeli company Skyline has a good list of markets and applications for their Terra engine.
  • Another Israeli company, GeoSim specializes in cities, with its own list of Solutions: Urban Infrastructure, Tourism/Travel, Real Estate, Security/Defense, Entertainment, Media/Advertising
  • Small areas of virtual terrain are called "Digital Terrain Modeling" by professionals in the civil engineering, landscaping, surveying and construction industries
  • The Defense Industry has always recognized the importance of virtual terrain.
    • they use terms like "Automatic Population of Geospatial Databases"
    • the line between military and entertainment is blurring, e.g. the Open Skies system claims to "show great promise as an actual training system as well as a unique and exciting game."
