  • 1. CONNECT. TRANSFORM. AUTOMATE. Bridging the Gap Between Unequal Partners Krischelle Love, GIS Technician San Jose Water Company
  • 2. The Gap CONNECT. TRANSFORM. AUTOMATE. many customers many needs many resources more land same needs fewer resources
  • 3. The Bridge CONNECT. TRANSFORM. AUTOMATE. San Jose Water Company !  140-mi2 service area !  2774 miles of water main !  230,000 connections !  350 employees Canyon Lake Water Service Company !  240-mi2 service area !  532 miles of water main !  10,000 connections !  40 employees
  • 4. Beware the Bridge Troll CONNECT. TRANSFORM. AUTOMATE. He’s demanding! If you want use of the bridge, you must have… !  enterprise GIS data maintained in an Oracle Spatial DB in California !  a viewing application for everyone in Texas !  a cloak of invisibility (a secure internal network for two-way data transfer) Photo Credit: "Troll Under the Bridge" by keystricken ©Attribution-ShareAlike License
  • 5. Danger: Bridge Out Ahead CONNECT. TRANSFORM. AUTOMATE. Limitations !  $$$ !  COTS unaffordable !  computers old & underpowered !  Rural area with slow/limited internet connectivity !  Security precautions further hamper our network connection (invisibility cloaks are heavy!) You Shall Not Pass Gandalf Vinyl Decal Sticker by Vinyl Decal Stickers
  • 6. Bridge Over Troubled Water CONNECT. TRANSFORM. AUTOMATE. Google Earth + FME
  • 7. Building the Bridge CONNECT. TRANSFORM. AUTOMATE. !  Oracle to KML !  KMLStyler !  LabelPointReplacer !  custom attribute display !  Advantages !  Free viewer !  Street View available !  Automated with FME Server
  • 8. Bridge to Nowhere CONNECT. TRANSFORM. AUTOMATE. !  Disadvantages !  Flat file " unmet need !  Excluded layers to control file size !  Secure file transfers failed often " stale data !  Unfamiliar interface " discouraging experience !  Users accustomed to traditional GIS interface !  Limited interest in learning new ways of doing same things !  Google Earth bulky and unreliable " few users ! Time for a new direction
  • 9. QGIS + PostGIS + FME Server The future is all about free & open source! (Plus, nobody needs money in the 24th century.) CONNECT. TRANSFORM. AUTOMATE. Bridge of the Future
  • 10. Making it so CONNECT. TRANSFORM. AUTOMATE. Oracle (enterprise data) Customized interface with a single plugin FME Server PostGIS (CA copy) PostGIS (TX copy)
  • 11. Engage! CONNECT. TRANSFORM. AUTOMATE. !  Add other sources !  Join customer database !  Add fields !  Hyperlinks (site specific) !  Symbol rotations !  Beautify line geometry !  Generalizer !  Appealing look !  Faster loading Adds value without clutter in the enterprise database! Still automated with FME Server!
  • 12. Bridging the Gap CONNECT. TRANSFORM. AUTOMATE. !  Users get access to… !  Engineering as-builts !  Tax assessor data !  Quick customer info !  Added value for users without ever leaving the map All at virtually no cost!
  • 13. We’ll Cross That Bridge When it Comes CONNECT. TRANSFORM. AUTOMATE. !  The future is full of possibilities… !  Interface can evolve with users’ needs !  Data from other sources can be added !  Other business needs can be met !  e.g., data entry directly by CLWSC staff to track leak reports, customer complaints, and more !  Growing staff ≠ growing expense !  Future unknowns are no sweat with FME
  • 14. Water Under the Bridge CONNECT. TRANSFORM. AUTOMATE. !  In summary… !  Google Earth was the right solution for a while, now it’s QGIS/PostGIS !  FOSS is unpredictable !  Business needs may will change !  FME is the key that unlocks whatever the future may hold !  FME Server is the caretaker that lets us pay attention to other things!
  • 15. Thank You! CONNECT. TRANSFORM. AUTOMATE. !  Questions? Ask me at! !  For more information: !  Quantum GIS: !  PostGIS: !  For a deep dive into customizing QGIS using Python: !  API to modify existing QGIS interface: !  Qt Designer to develop new interface: !  PyQt to talk Python to Qt (and avoid coding in C++): !  QGIS Plugin Builder to get new interface into QGIS:
