TRANSCRIPT
Data Integration, Computer Aided Dispatch with GIS, and Enterprise GIS Implementation in Sun Prairie
City of Sun Prairie
Presented by
Andy Swartz
AKA “The City That Swalloweda Fly”
There was an old lady who swallowed a fly. I don’t why she swallowed that fly,Perhaps she'll die.
City of Sun Prairie – Geography and Demographics
Fastest Growing Community in Wisconsin Expected Population Increase:
~ 20,000 to ~ 35,000 by 2020 Straddles 4 Townships 5% of Dane County Population, but Growing
Twice as Fast. Maintains a Public Safety Dispatch center

Trends
Economic Crunch – Leverage Technology Need to limit Property Tax Increase Residents Demand More or No Less Services Public Safety Data Demands – Post 9/11 Convergence of Police and Emergency
Services Fleet Management Demand for MORE Data
FOCUS - Three Major Areas
1. City Government Data Integration2. GIS Interface for Computer Aided
Dispatch3. Enterprise GIS Implementation
1. CITY DATA INTEGRATION
Data Integration
The
IDEA…
… Became a VISION
Data Integration Goals
Easier to Share Data Reduce Redundancy in Data
Collection & Storage Improve Accuracy of Data Increase Use of Data/Maps Internally –
Reference, Decisions, Analyses, Public Input
Increase Usability and Accessibility for public – Future Web Interface (manage calls/visits)
Data Systems Integration – Key Components
Existing MS Access Databases (Inspection, Assessor, Clerk) Hansen – City Management System
– SQL Database– GIS Viewer Function
AutoCAD – Drawings (Engineering, Water and Light) Global – Public Safety Applications Suite
– MapInfo Based Finance and Assessing Software Systems Enterprise GIS – Centrally Managed Data Source
City’s Data Needs – Three Types
Parcels– taxable – non-taxable
Property Addresses Contacts
– Occupant– Owner– Property Manager
Hansen Systems – City Management Software Suite
•MapObjects GIS Functions•Several dozen modules available•SQL database platform•Downfall = No CAMA for assessing (so far)
2003 Modules Purchased & Implemented•Building Inspection•Code Enforcement•Planning 2004 Modules•Stormwater•Public Works www.hansen.com
Hansen – Integrated GIS Viewer
Features are Linked to Hansen’s “Property Browser”
Example – Contractors Associated with a Specific Permit
Hansen Implementation Exposed Data Quality Issues
Timeliness– Hansen System = Real Time >>>> Users want data NOW– Historic lag in County assigning parcel #’s
Tabular Data Incompatibility– Different Standards– Street type suffix abbreviation mismatches (LN vs. LA)
Accuracy - Spatial– GPS errors– Ortho photo accuracy limitations– Projection issues– Typos in Attributes
Completeness– E.g. Parcel address but no BUILDING address– Condos handled differently – no local approvals
Parcel and Address Flow - Current
Parcel & Address Flow - Ideal
Need = Street Naming & Addressing Standard
Data Initiative – Proposed Ordinance Changes & Standards
Roadway Naming Standard– Significant Dispatch issue (Broome/Broom, Scheuerell Street)
Addressing standard– Consistency– Corrections– Annexed properties
Address Placard (passed) and Roadway Name Signage Standards (pending) E-submittal of plats/CSMs
– Required– Standards (DWG or ESRI, in Dane County Coordinate System)
Developer to Provide Tabular data for plats/CSMs– Avoids hand-assembling the data– Facilitates faster input to systems
Goals of Property Addressing and Roadway Naming Standards
Reduce ambiguity Speed Use of Computer
Aided Dispatch System Aid in Crime/Incident
Reporting and Crime Analyses
Minimize Data Maintenance Issues
Designate Address Authority
New Subdivision Information Requirements
Addressing Plan prior to Final Plat Approval Electronic copies of Final Plats and Certified Survey
Maps (CSMs) “Subdivision Information Spreadsheet”
– Lot Size– Intended Use– Current Zoning– Property Address/es– Etc.
New Property Addressing Systems
Creates Property Addressing Authority Signs to Indicate when Entering and Leaving
City Addressing Scheme Addressing to be Done Before Plat is Approved Annexations
– Change address to City system– Address EACH annexed parcel
Address Change Process
Three Major Areas
1. City Government Data Integration
2. GIS Interface for Computer Aided Dispatch
3. Enterprise GIS Implementation
2. COMPUTER AIDED DISPATCH – GIS INTERFACE
Global Software’s Computer Aided Dispatch with GIS
Computer Aided Dispatch (CAD) = Good GIS Functionality = Limited Map-based, uses MapInfo Problems with Orthophotos, etc. Conversions and Updates - Laborious http://globalsoftwarecorp.com/
TASKS - Street Centerline Map & Master Street Address Guide
Is a Street Segment Driveable? – Yes/No Correct Left/Right FROM – TO Numbers (e.g.
701 – 755 Elm Street) Reconcile with other MSAGs (e.g. Intrado) Add New Subdivisions – Timing Critical Add New Certified Survey Maps (CSMs) Add New Addresses
MSAG Analysis – Unnamed Roadways
Dispatch Discrepancy Management
Created Custom Dispatch Discrepancy Management Tool
Three Major Areas
1. City Government Data Integration2. GIS Interface for Computer Aided
Dispatch3. Enterprise GIS Implementation
3. ENTERPRISE GIS IMPLEMENTATION
2004 Projects
Base Layer Construction – e.g. Accuracy of Corporate Limits, address range grid
ArcSDE – DBMS/Geodatabase Implementation Convert Individual AutoCAD files and assemble to complete
layers (e.g. hydrants, “Knox boxes”) GPS Locate Additional Infrastructure – New Layers Site Plans for Fire Department
– Contracting for Data Collection– GIS/Data Software on Mobile Data Computers
Bring Several Departments Online with GIS– ArcExplorer (Free Client)– ArcView Floating– Hansen GIS Viewer
2004 Projects - Continued
Data Quality Control Roadway Sign Standards Hansen in wireless mobile environment ArcSDE Implementation Funding Approval for 2005 GIS Coordinator Position Roadway Name Corrections Property Address Corrections Property Number Display Standard Enforcement Central Address Database (Convert Hansen from
Building/Code Enforcement/Zoning only to repository for ALL City property addresses)
PROJECT - Map Subscription Service
Needs– Version Control– Efficient use of Staff Time– Convenience for End Users
Outcomes– Central Repository– Email Update Notices– Hard/Soft Copy distribution
Users– Assessor– Dane County 911 Center– Fire/Police/Emergency– Water and Light– Stormwater Utility– School District
PROJECT – Data Subscription Service
Needs– Version Control– Efficient use of Staff Time– Convenience for End Users
Outcomes– Central Repository– Email notices– Hard Copy distribution– Soft Copy distribution
Subscribers– County Property Listing– County 911 Center– Mapping Services– City Assessor
FUTURE STEPS – Routing and Automatic Vehicle Locator (AVL)
Make Street Centerline Map Routable
– One-way streets– Construction closings– Multiple Street Names– Acceptable Turns– Nodes correct
FUTURE STEPS – Site Locations
“Deluxe” Dispatch map would have site locations:– Driveway/street Centerline Intersections– Buildings– Outbuildings– Points-of-rescue– Etc.
FUTURE STEPS - Maintenance
Maintenance Maintenance Maintenance
Future GIS Uses
Push-pin for EMS Runs– Analysis of Trends, Staff Allocations, etc.
Crime Analysis Site Plans for Fire Department Public Works Route Planning Etc.
CONCLUSION: From the Vision,One Thing Led to Another
Data Integration & CAD Led to… City Management Software Suite … Enterprise GIS + Data Quality Initiatives + Data Model Initiatives … Need for GIS Data Base Management… Geodatabase via ArcSDE… Leads to…. ???
