7. Map Changing Problem
• Cadastral Across Europe
• Land Use Maps
• Raster Images Pattern Recognition
• Distributed Databases * data normalization problem and
cross domain reference

10. OPEN MI from 50000 ft Above
• State machine *each state represents an object *aspect behavior
• Model Linking. *Mostly Environmental and Water
• SDK under GPL. GUI for Model Linking under
BSD.
• .NET and Java Support
• Currently no .NET and Java model Integration.
• GUI editor only for .NET. *Mono Supported ;-)
