GIS Business Case and Geodatabase Review Solid Waste Authority April 2, 2008

Agenda  Project overview  Wiki site orientation  Business Challenges & Drivers  Geodatabase Design Review  Recommendations

Project Scope  Task 1: Business Use Cases  Task 2: ArcGIS Geodatabase Design  Task 3: Convert Atlas to ArcGIS Geodatabase  Wiki site: 

Business Challenges  Contractors digging and hitting underground utilities  Difficulty locating assets in the field that are damaged or buried/covered  Difficulty locating spare parts in storage  Lack of single authoritative source of utilities as-built location information  Inability to organize into one place related facility content: CADD, structured maintenance, free text and rich information (images, pdf's, documents)  Errors introduced through manual transcription processes  Inability to access or update utility asset and maintenance record information while in the field  Inconsistent color marking utilities in the field  Difficulty accessing source information (engineering drawings, permits, manufacturer specifications)

Business Drivers  Build Utilities GIS Database  Preventative maintenance programs  Protect utility assets  Permit compliance  Situational awareness

Geodatabase Design Review  Utility Classes  Landfill site - cell boundaries, wellfield zones  Leachate collection system - manholes, meters, valves, pumps, lines, clean outs and associated  Gas collection system - wells, meters, valves, lines and associated  New Features  Utility incidents  Construction project boundaries

Geodatabase Structure

Geodatabase Maintenance  Phase transition from Atlas to GIS  Convert the gas and leachate utility point and line features in the pilot project area to ArcGIS  Add topology to the geometry and populate attributes  GIS becomes authority source  Record changes in both the GIS and Atlas  Transform additional Atlas drawing layers into GIS features for reference purposes  Atlas continues to be the authority source for these features  Transition all geographic features from the Atlas to the GIS database over longer term

Recommendations 1. Build comprehensive GIS utility database for NCRRF, filling in content missing from Atlas system 2. Stand up and link to GIS a wiki system or similar to manage free text utility information 3. Build or purchase applications that enable access to utility maps using mobile devices 4. Build or purchase applications that enable text, GPS coordinates, digital image, and utility records input using mobile devices 5. Link to GIS permits, utility maintenance records, equipment specs and operation manual content

Recommendations (continued) 6. Extend SWA utility information access to engineering, construction and maintenance contractors 7. Define common vocabulary and information for utility assets that spans GIS, wiki and other SWA systems 8. Modify business processes and construction contract language to use new GIS resources before digging 9. Develop plan to transform all features from Atlas system to GIS 10. Document data dictionary for GIS & CADD in a wiki system or similar
