Transcript

  • 1. The cartographic vision Ed Parsons <ed.parsons@ordnancesurvey.co.uk> Chief Technology Officer October 2005
  • 2. Ordnance Survey - key facts There is much more to Ordnance Survey than you might think...  Market leader with more than 200 years of mapping expertise  Data underpins around 10% of Great Britain's economic activity  Financed through data licensing rather than direct funding from taxpayers  More than 50% trading revenue comes from non-public sector customers  At the forefront of the drive to provide intelligent geographical information 2

  • 8. Database centric cartography - Ed’s golden rule 1 “Separate representation Ordnance Survey Land-Line from data” Ordnance Survey MasterMap 9
  • 9. Database centric cartography • Geometry is just an attribute ! • Multiple geometry's associated with a single feature • Multiple cartographic representations associated with each feature Feature Geometry’s Representations 10
  • 10. Database centric cartography Digital Digital Real World Landscape Cartographic Models Models 11
  • 11. Rebuilding the Factory 12
  • 12. Project “Phoenix” • Multi-Million Euro investment programme to allow seamless object editing of core Digital Landscape Model • Supports Long Transactions • Basic service orientated architecture 13
  • 13. Job Management Tool Product Store Editor Transaction Service Product Adaptor Generalisation Agent Maia Core DLM Archive Derived DLM 14
  • 14. Cascading DLM’s DCM Production DLM 250K ? DCM Production DLM 100K ? DCM Production on ti a lis DLM 10K ? ra ne e G Source DLM 15
  • 15. Generalisation • Modifying the relative location and geometry of features • A difficult problem to automate • Current ‘best” solutions rely on AI systems e.g. LaserScan Clarity 16
  • 16. Conclusions • Database centric cartography requires an shift in organisaition thinking • Huge benefits from deriving products from a “single source of truth” • New ESRI cartographic representation tools are a massive step forward • Generalisation is still a difficult problem • Operational solutions must support interoperability between systems 17
