SYSTEM 9 to SpatialWare to LBS

• SYSTEM 9 -gt1984 - Toronto, London,
  Heerbrugg(Zurich)
• state of the art mapping, GIS system based on a
  DBMS that would survive until the next century
• SpatialWare -gt 1989
• simplification of the topology model to support
  implicit topology dropped explicit and
  versioning
• introduced ATB (tcl/tk based interface)
• SpatialWare -gt 2001
• miPro core foundation, GML engine, sql/server,
  mapXtend
