CONNECT. TRANSFORM. AUTOMATE.
Bridging the Gap Between Unequal Partners
Krischelle Love, GIS Technician San Jose Water Company
The Gap
CONNECT. TRANSFORM. AUTOMATE.
many customers many needs many resources more land
same needs fewer resources
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
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)

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!)

Bridge Over Troubled Water
CONNECT. TRANSFORM. AUTOMATE.
Google Earth
+ FME
Building the Bridge
CONNECT. TRANSFORM. AUTOMATE.
! Oracle to KML ! KMLStyler ! LabelPointReplacer ! custom attribute display
! Advantages ! Free viewer ! Street View available ! Automated with
FME Server
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
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
Making it so
CONNECT. TRANSFORM. AUTOMATE.
Oracle (enterprise data)
Customized interface with a single plugin
FME Server
PostGIS (CA copy)
PostGIS (TX copy)
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!
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!
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
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!
Thank You!
