Company Property Assets: Leverage GIS to Provide Access & Analysis
1. Determine data requirments2. Locate record in various databases3. Compare / conflate various records4. Open map document5. Open attribute selection tool6. Zoom to block / lot7. Change all surround elements8. Change overview map9. Query on watershed, various overlay layers10. Edit title block w/ specific information11. What if parcel data is bad?12. Edge-match13. What if it doesn't match our records?14. More Research15. What if block / lot geometry unavailable?16. Find electronic tax map, download image17. Locate property in GIS18. Geo-reference19. Digitize20. What if tax maps missing?21. Contact legal department for deed22. Digitize from Metes & Bounds in deed23. Export finished product.24. What if someone requested 80 such maps??
“The Old Way”
Hypothetical GIS Property Request Workflow…

Business Reality
Over 500 properties across state Existing databases vary in completeness & formatting:
Tax, Legal, Environmental Compliance, Asset Planning, etc Satisfy the individual needs of departments Not comprehensive; No uniform mapping component Insufficient for Regulatory or Management:
- Map requests
- Comprehensive data requests
- Requests that require spatial overlay
- Spatial or attribute query requests
- GIS analysis requests No “Self-Help” … all property map requests require research. Bulk Requests can take weeks to compile

Business Need
Seamless property database in GIS
Simple schema with logical key field (PAMS)
Dynamic Template to respond quickly to GIS requests Automate common overlay requests Automate map production
Web Access for “Non-GIS” users Easy search & query, identify, print tools Environmental Chart tools Industry friendly base map

Objective
The objective of this project is to create efficient ways to access, analyze, & edit New Jersey American Water property information along with related, contextual GIS layers.
Goals:The primary goal is to design and build an up to date, seamless GIS
property layer for New Jersey American Water.
The secondary goal is to provide efficient ways to access, analyze, query, edit, and print property information for end users with and without GIS knowledge.
The tertiary goal is to design a base map that uses cartographic design principles to support users in a variety of web-based geospatial water utility tasks.

Database Population
• Start with tax record• Compare to other databases• ** Normalize / conflate data **• Locate property in existing parcel layers• Copy into geometry into property layer
If no existing parcel GIS available… Log into E-Taxmaps.com Save tax map as .tiff format Geo-reference Digitize outline in NJAW layer
• Repeat (~500 times)
