The Really Big Job Integration of GIS into the Daily Business Process

Old Ways and Methods Hand Drafting to CAD (mid 1980s)

Slide Rules and Planimeters Old Ways and Methods

Compasses and Dividers to Technical Pens Old Ways and Methods

Computer Aided Drafting Drafting moves from the drafting table

Processor Speed Approaching 16mhz Up To 16MB of 80ns RAM 140MB Hard Disk Drive Only Cost 10K Computer Aided Drafting To The Personal Computer

We even have Laptop Computers Computer Aided Drafting

AIMS had the data, but the County’s IT Infrastructure (no wide area network) limited access to the data. ArcInfo running on UNIX platform. AIMS server is in the “dungeon” in the Courthouse basement. JCW doesn’t have any dedicated GIS people until early 90s. Still No GIS at JCW!

Installation of dedicated phone lines allow connectivity through terminal emulation (Tektronix X Terminal, and later terminal emulation software on Windows desktops). Up to this time any large mapping requests are filled by AIMS staff, and couriered to Wastewater staff. Limited GIS Available

Installation of T1 line between County Admin Bldg and Wastewater Offices allow full access to all data. Allows creation and maintenance of Wastewater data on UNIX server. Still accessed through terminal emulation software on Windows desktops. Still on UNIX platform. Full GIS Capabilities

UNIX platform is replaced with Windows NT server. All AML’s converted to access data on Windows platform. Allows Wastewater to maintain it’s own data locally, AIMS data is replicated to JCW’s GIS server nightly. No more terminal emulation software. Full GIS Capabilities Part 2

GIS Now a Reality Windows platform, and new server configuration allows JCW to expand all capabilities in offering GIS products. Primarily data maintenance and mapping, but lots of “what if” analysis is now performed for new sewer planning. All GIS functions performed by 2 people.

ArcInfo to ArcGIS In between ArcInfo and ArcGIS came ArcView. Not a great solution for JCW, but did expand GIS capabilities to several more end users. ArcExplorer gave a limited GIS capability to even more Engineering Staff members.

“During my service in the United States Congress I took the initiative in creating the internet. I took the initiative in moving forward a whole range of initiatives that have proven to be important to our country's economic growth and environmental protection, improvements in our educational system”. (March 9, 1999 CNN Interview) Thank Goodness, Senator Albert Gore Invents the Internet!!!

Fast Internet Access is Key In the fall of 1990 there were just 313,000 computers on the Internet; by 1996, there were close to 10 million. Campbell-Kelly and Aspray: Access to high speed “T1” internet connections allows all JCW users access to the AIMS IMS website.

Access to the IMS site is enhanced by adding sewerline and manhole layers. A pilot program was initiated to provide access to scanned as-built drawings via the IMS website. The program was a huge success. Drastically changes how we conduct our business. Fast Internet Access is Key

More than 21,000 D size (24”x36”) drawings were scanned as TIFF images, converted to PDF, and now reside on a separate server that the IMS site accesses. GIS Day to Day

Reduces office and phone traffic dramatically by directing request for as- built information to the AIMS IMS site. Plumbers, consulting engineers, (both local and out of town) can obtain connection information from the IMS site. No more long lines or parking problems.

Today 30+ users access My AIMS daily for various reasons. Many users in O&M. Sewer connection permit issuance Sewer extension plan review Commercial connection permit reviews Plat searches CUEView (collaborative utility exchange viewer) GIS Day to Day

Other uses include: DDR (digital data request) JCLR (Johnson County Land Records) Address Locator GIS Day to Day

Recent changes: Conversion from personal geodatabase featureclasses to SDE featureclasses Syncronization of sewer featureclasses with GBA Master Series Computerized Maintenance Management System (CMMS) GIS in the Future

Conversion to digital submittal of as-built and attribute information. Continued integration of GPS to position correct manhole locations. Establishing protocols for exporting to hydraulic modeling software, and importing updated attribute data. GIS in the Future

Future Plans: Mobile GIS and mobile CMMS. Maps and work order processing in the field. Using GIS in conjunction with automated asset management system. GIS in the Future

Future Plans Continued: AAM Automated Asset Management Key to Sustainability Understanding how our assets fail!

The Five Core AM Questions What is the current state of my assets? What is my required sustained level of service? Which assets are critical to sustained performance? What are my best minimum life cycle costs CIP and O&M? What is my best long term funding strategy? Future Plans Continued:
