Wausau Department of Public Works - GIS Division 1.Developing a Digital Inventory - History: Paper to Digital - Adapting/Migrating Digital Systems 2.Maintaining the Digital Inventory 3.Low cost solution for digital map books - Developer sample and PDFs

Wausau Department of Public Works - GIS Division Wausau Water Works Service to over 14,300 households 200 miles of water - sewer mains 1,380 fire hydrants 21 sewage lift stations Treats1.5 billion gallons of water annually

Wausau Department of Public Works - GIS Division In the beginning ….(there were paper maps)

Wausau Department of Public Works - GIS Division Developing Digital Inventory (Water and Sanitary Sewer – Round One) Water and Sanitary Sewer utility mapping began 1997 Used BaySys/GeoIT/KEMA software and data modeling expertise First attempt to determine necessary features in data model Features collected with GPS

Wausau Department of Public Works - GIS Division Maintenance? But, I’m not done mapping!

Wausau Department of Public Works - GIS Division Maintain the Digital Inventory Have an update strategy in place before data conversion begins –What type of changes can occur? –How will GIS editor be notified of changes? –How often will digital inventory be updated? –How many edits are anticipated? –“Map” out the workflow to cover all possibilities

Wausau Department of Public Works - GIS Division Keep it Simple – Paper Trail -Edits manageable with paper trail -Good communication between departments -Education process for field staff to see what information can be captured -‘Seasonal’ updates following construction season coincide with yearly map book printing

Wausau Department of Public Works - GIS Division

Maintain the Digital Inventory Water Utility: –tracking hydrant flushing, freeze-ups, breaks, leaks Sanitary sewer: –tracking: rodding, jetting, flushing,video surveys Storm Utility: –tracking cleaning activities

Wausau Department of Public Works - GIS Division System Benefits – Future Plans

Wausau Department of Public Works - GIS Division Benefits Complete digital inventory with ability to query, display and create maps at any scale Accurate positional accuracy (not relative accuracy anymore) Ability to quickly share digital information with developers, and engineers for site design Automated map book process –Blue-print machine removed, reduced staff time Increased available office space (no more map cases) Faster response time to satisfy requests for information

Wausau Department of Public Works - GIS Division Future Plans Move to multi-user environment/database –“SDE in 2003” –To give water/sewer utility staff ability to edit maintenance reports/data New GPS and base (Survey Grade RTK) Develop an ArcIMS Utility Viewer Storm Utility: Finish?!?!?!? –East side completed. Working westward. –Slow process due to many new features never mapped before (inlets and laterals) Field access?
