1. Mobile GIS at Jackson Energy Authority - A Case Study Charlie Marlin - Graphic Technologies, Inc. (GTI)

2. Charlie Marlin – Graphic Technologies, Inc. (GTI) Jackson Energy Authority (JEA) Madison County, Tennessee Population:92,000 people 37,000 households

3. Charlie Marlin – Graphic Technologies, Inc. (GTI) Jackson Energy Authority (JEA) Multiple Utilities: Electric 33,589 Gas customers28,760 Water customers33,856 Waste water27,519 Propane customers: 3,131 Fiber 14,485

4. Charlie Marlin – Graphic Technologies, Inc. (GTI) Jackson Energy Authority – GIS GIS in place for several years Added mobile GIS in summer of 2004 Extract data from GIS and copy to laptops Disconnected view, analysis, and sketch Data refreshed weekly via WLAN

5. Charlie Marlin – Graphic Technologies, Inc. (GTI) JEA – Mobile Use (Electric) Each crew foreman has a laptop with the data Asset identification in the field: What is this? Preliminary design sketch using redline layer

6. Charlie Marlin – Graphic Technologies, Inc. (GTI) JEA – Mobile Use (Gas) Asset identification in the field: What is this? Preliminary design sketch using redline layer Related documents

7. Charlie Marlin – Graphic Technologies, Inc. (GTI)

9. JEA – Mobile Use (Water and Waste Water) Asset identification in the field: What is this? Layout has been done by property developer Facilities built by property developer Facilities purchased by JEA if meet approval

10. Charlie Marlin – Graphic Technologies, Inc. (GTI) JEA – Mobile Use (Propane) Asset identification in the field Is this one ours? Smaller number of customers

11. Charlie Marlin – Graphic Technologies, Inc. (GTI) JEA – Mobile Use (Communications) Asset identification in the field: What is this?

12. Charlie Marlin – Graphic Technologies, Inc. (GTI) JEA Special Project 1 Color-code fire hydrants by pressure Use mobile GIS to identify hydrants and pressure Three paint colors

13. Charlie Marlin – Graphic Technologies, Inc. (GTI) JEA Special Project 2 Lock Change-out Chain link fence with padlock around each gang- operated switch Mobile GIS for navigating and locating Task performed by summer students Reduce labor costs – technology allows a less experienced, less skilled person do the work

14. Charlie Marlin – Graphic Technologies, Inc. (GTI) JEA Special Project 3 Vegetation Management(7 syllables) Tree-trimming(2.5 syllables) Contractor gets laptop with mobile GIS data Records enable continuous improvement Rates of growth Frequent-cut corridors All marked on map

15. Charlie Marlin – Graphic Technologies, Inc. (GTI) JEA Special Project 4 Pole inspection Preservative treatment Ground condition (other utilities do joint use audit) Mobile GIS aids in navigation, identification, and recording of inspection on the spot Inspection results go back to office without re- entry

16. Charlie Marlin – Graphic Technologies, Inc. (GTI) JEA Special Project 5 Coordinate switching operations Everyone on the same page Field worker on radio to Operation Center tells them what he is about to do Operation Center makes change a the same time Safety benefit

17. Charlie Marlin – Graphic Technologies, Inc. (GTI) JEA – Rugged or Non-rugged Decision to go with Non-rugged laptop Ownership by users Consider their personal machine Permitted to use at home for email Many departments (and some individuals) bought hard- shell cases with foam inserts Some individuals bought laser mouse Failure rate: one lost in three years Every machine still viable Now at end of service life, to be replaced

18. Charlie Marlin – Graphic Technologies, Inc. (GTI) JEA – Rugged or Non-rugged Alternate approach Bolt to truck mount Laptop never leaves the truck Non-rugged failure rate: 100% JEA conclusion: If running all the time, probably need rugged laptop. If unpack for each use, non-rugged probably OK.

19. Charlie Marlin – Graphic Technologies, Inc. (GTI) Benefits: hard, soft, and in-between

20. Charlie Marlin – Graphic Technologies, Inc. (GTI) Benefits: hard, soft, and in-between Sharply reduced printing of paper maps JEA estimates annual savings of $50,000 Efficiency More production with same number of people Reduced radio and phone calls to Operations Center Volume down over 50% No more questions about measurements: “How many feet from the street centerline is the gas main?” Picture worth 1,000 words Considered primary benefit

21. Charlie Marlin – Graphic Technologies, Inc. (GTI) Benefits: hard, soft, and in-between Dig in the right spot Safety. How much does an accident cost? Zero downtime for GIS data.

22. Charlie Marlin – Graphic Technologies, Inc. (GTI) Benefits: hard, soft, and in-between Morale, trust, empowered workforce Build skills for future technology Better decisions in the field Less time to reach a good decision People who use the mobile GIS came up with the best ideas. The hydrant painting use did not come from IT.

23. Charlie Marlin – Graphic Technologies, Inc. (GTI) Costs: hardware, software, infrastructure Major cost component Hardware decisions Rugged or not. Half-rugged? Laptop, hand-held, phone, “tweener

24. Charlie Marlin – Graphic Technologies, Inc. (GTI) Costs: hardware, software, infrastructure Usually the least cost component Implementation options Major GIS vendors Third-party vendors In-house solutions

25. Charlie Marlin – Graphic Technologies, Inc. (GTI) Costs: hardware, software, infrastructure Much of the infrastructure cost is sunk. GIS system and corporate network already in place. Additional infrastructure to support mobile GIS: Need stable pipeline from server to local office. Had wireless routers. Invested in switch gear. Diverted IT staff time. May consider “sunk”. R&D needs to be recognized as a cost. “research and discovery”. Flounder until get the light-bulb moment. Battery life is a factor. Bought new power inverters for trucks.

26. Charlie Marlin – Graphic Technologies, Inc. (GTI) Summary Mobile GIS is not impossible In fact, it is a high-leverage application Many thanks to Jon Taylor at JEA
