Simulation software

There are a number of consumer software packages which focus on simulation.  The focus on accuracy puts them somewhere between games and "real" training simulations.  Because they need to model the real world, they tend to contain a fair bit of virtual terrain functionality.

Flight Simulators in particular have historically tackled the world modelling problem in very closed, nonstandard ways, see Leveraging the Flight Simulation Field.

• Microsoft's Flight Simulator and Train Simulator are mentioned on Microsoft Terrain Software
• Flight Gear / TerraGear (free, open-source, cross-platform)
• Sail Simulator (€40, Windows only)
• Virtual Sailor ($25, Windows only)
  • Has an active user community producing nice-looking scenery.  Since the scenery is meant to be seen from a boat, it has a definite emphasis on shorelines and landmarks.  See their Add-on Scenery page which tends to focus on the USA, the Mediterranean, and important shipping canals.

  If you know of other simulation software that should be listed here, please let us know.
