Unit-Level Addressing for GIS Jeremy Jobe, Woolpert, Inc. Missouri GIS Conference Unit-Level Addressing for GIS Jeremy Jobe, Woolpert, Inc. Tuesday, February 22nd, 2005
Introduction Who am I? Topics to Discuss Project Background Problems to Solve Why Inventory Units? Unit Inventory: How? Unit Inventory: What to Collect Unit Data GIS Input: How? Lessons Learned
Project Background Client Project Area City of Indianapolis, IN Information Services Agency, GIS Division Indy GIS Master Address Database Project Area Indianapolis/Marion County, IN 9 Townships +/- 770 Apartment/Condo Complexes +/- 100,000 Units to Inventory
Indy Master Address Database What is it? Comprehensive Address Source Oracle-based Geography-based Maintenance Tools Address Cleanup Tool Validation Web Service What does it contain? Centerline Address Ranges Parcel Addresses Building and Unit Addresses Street Intersections Subdivisions Building Names
Problems to Solve Problems: Didn’t know how many properties existed Didn’t have any idea how many units existed Centerline ranges weren’t accurate Some real-world centerlines didn’t exist in the GIS Some GIS centerlines didn’t exist in the real world
Why Inventory Units? Better Emergency Response Verifiable Residences for Offenders Improved Centerline Address Ranges More Accurate Geocoding Better Customer Service for Public Works Dept. Better Communication Between Departments Problems: Didn’t know how many properties existed Didn’t have any idea how many units existed Centerline ranges weren’t accurate Some real-world centerlines didn’t exist in the GIS Some GIS centerlines didn’t exist in the real world
Unit Inventory: How? “Hi! Can you fax a map of all your units to me?” Doesn’t Work “Drive-Bys” Don’t Work Data Starting Point Complex Polygons Centerlines Building Outlines Building Addresses Start Walking
Unit Inventory: What Was Collected? Centerline Names Unit Addresses Unit Locations
MAD Maintenance Tools Purpose: Synchronize GIS and MAD Data Features Included Parcels Centerlines Buildings and Units
Unit Data GIS Input: How?
Lessons Learned Have Proper ID Be Polite Don’t Stand Behind Parked Cars Great Way to “Evangelize” Access Is Sometimes a Problem 3D Addressing???
Summary Unit Addresses Are Valuable Have a Plan Before You Collect Unit Addresses Always Change
