  1. 1. Going ‘hybrid’ open Simon Miles Royal Borough of Windsor and Maidenhead
  2. 2. 1 of 17 The Proposal? • • • • • • Current GIS stack Proposed GIS stack Savings Architecture Timescales Some other stuff!
  3. 3. 2 of 17 The recommendation #FROM: 54 ArcView (single) licenses 5 ArcEditor (Concurrent) licenses 1 ArcGIS Server 1 SDE instance 1 ArcInfo #TO: QGIS Postgres/PostGIS instance iShareGIS Map-Modeller # Saving around £15k in Yr one
  4. 4. 3 of 17 Why move? # Demand # Scalability # Cost savings # Technology # I wanted GIS on every desktop!
  5. 5. 4 of 17 Desktop GIS! Benchmarks QGIS: CAN # # # # # # # Edit shp, PostGIS Query features Print map View WMS etc Open shp, tab, kml etc Smaller hardware footprint Can be virtualised No license costs associated with scaling up!
  6. 6. 5 of 17 Database GIS! PostGIS: CAN # # # Do everything SDE did No Oracle license Deploy multiple instances
  7. 7. 6 of 17 Web GIS! Astun: CAN # # # # Out of the box solution Talks to PostGIS Smaller server footprint Cheaper than ArcGIS Server!
  8. 8. 7 of 17 Map-Modeller! # The divorce settlement! # Like for Like replacement from ArcInfo # Talks to PostGIS!
  9. 9. 8 of 17 The Users # # Enthusiastic for change One main question; “will it be faster than what we have?”
  10. 10. 9 of 17 Management # Happy with solutions # Happy with costs # Get on with it!
  11. 11. 10 of 17 The plan? # Replace ArcMap with QGIS, over six months, dept. by dept. # # ArcSDE with PostGIS, using Astun Tech’s Studio # ArcGIS Server with iShareGIS, over a week, to all ArcGIS Server users! # Train staff # No holidays!
  12. 12. 11 of 17 Phase 1 – Pre User Implementation # Get PostGIS onto a Server # Redesign schemas and tables # Migrate data from ArcSDE to PostGIS Planning Policy guinea pigs # # # # Middle of the road Had lots of data Wanted change – Ratio 1:6 Had the time to help!
  13. 13. 12 of 17 Phase 2 – User Implementation # Migrate ArcGIS Server users to iShareGIS # Move staff to QGIS dept. by dept. # Arrange training # Keep users informed
  14. 14. 13 of 17 How? # Studio behind the scenes did the grunt work! SDE data
  15. 15. 13b of 17 How? Dept A Dept B Dept C SHP
  16. 16. 14 of 17 The Architecture
  17. 17. 15 of 17 Feedback Q. How do you find using iShareGIS? 91% 9% Hard Q. Given a choice of using ArcView or QGIS Which would you choose? Easy 27% ArcView 73% QGIS
  18. 18. 16 of 17 Shortcomings / Lessons Learned # Notes – very important things # Lots of learning! # Not totally ESRI free # Database design # Community help
