1 Integration of GIS into Policing Valdosta, Georgia

2 Valdosta, Georgia Total population: 50,000+/- Households: 18,900 Road miles: 293 South Georgia RDC South Georgia RDC One of sixteen RDCs in Georgia Serves a nine county region Mission: Provide professional planning and technical assistance to facilitate orderly growth and economic development. V. P. D. Sworn police officers: total calls for service: 67, total part 1 crimes: 3,444 CALEA accredited agency since 1999

3 The VALOR M.O. M.O. Foundation of VPD Project Funded by city & county Constructs/Maintains/ Distributes ALL GIS data for Valdosta-Lowndes All data is co-owned & shared

4 Commission on Accreditation for Law Enforcement Agencies Over 450 Standards Address: Roles and responsibilities of agency Organization, management and administration Personnel structure Personnel process Operations Operational support Patrol Criminal Investigation Crime Prevention Traffic operations Prisoner and court-related activities Auxiliary and technical services only 700 Agencies Nationwide 36 in Georgia Valdosta PD Flagship Agency

5 GIS makes the rounds Dispatching Patrol/Traffic Investigations Prevention & Outreach

6 Dispatching GIS E-911 Dispatching utilizes continually updated VALOR GIS data for automated suggestions All calls for service logged in AS400 database with dispatch time, arrival time, etc.

7 Responding with GIS Road Atlas now a part of officer training manual (911 data product) ROAD ROAD ATLAS ATLAS for Lowndes County, Georgia. Including the communities of Hahira, Dasher, Valdosta, Remerton and Lake Park. Same street & beat data as 911 dispatch This document was produced by South Georgia Regional Development Center, Valdosta, GA. The following maps are a graphic representation of the VALOR road database. On-board address locates - no more cross-street requests of dispatcher Last 30 days of crimes at their fingertips Other information Speed limits Property ownership Patrol zones Landmarks (Schools, Churches, etc.) Data exchanges/updates are one click away. ArcExplorer on MDT S in ALL 132 VEHICLES New AVL/GIS app is being developed. More details later

8 Pushing each others buttons..

9 One crime at a time Data acquisition All incident reports are keyed in via MDTs and/or VPD records division and linked with dispatch records Data is acquired by VALOR staff Incidents are geo-coded GIS data used for analysis and placed on servers for access by VPD patrol and detectives

10 This is great! Now what do I do with it? Difficulty in identifying overall patterns What about the frequencies of incidents? How to identify problem areas? Find a path from raw output to usable product through analysis -- What do they need to see? How can we show it to them?

11 Getting dangerous with density March 07 All Crime March 07 Crime Density Areas of Concentration Patrol: Where? Investigative Services: Why? Crime-Specific

12 Getting dangerous with density March PART 1 Crime Density March PART 1 Crimes Areas of Concentration Patrol: Where? Investigative Services: Why? Crime-Specific

13 Getting dangerous with density March 07 Residential Burglary Density March 07 Residential Burglaries Areas of Concentration Patrol: Where? Investigative Services: Why? Crime-Specific

14 B.O.L.O. B.O.L.O. GIS.... Residential Burglaries - Directional Distribution by Time of Day (1 Stnd. Dist.) Directional Distribution: Standard deviational ellipse further illuminates trends Might identify a relationship to particular feature or condition or nature of perpetrator? Taking it further Neighborhood Analysis (Neighborhood Watch) Housing Type Land uses/zoning Patrol zones Calls for service Natural features, etc., etc

15 A new perspective on crime 3-D Crime Incident Density

16 GIS behind the desk Investigative Bureau GIS tools in use today 1 seat of ArcView 9.2 ArcExplorer on Investigations supervisors desktops Weekly & Monthly Density & Dir. Dist.. Burglaries (Residential, Commercial) Robberies BEAs (Breaking/Entering Autos) By Patrol Zone, Day of Week, Time of Day Reports Linking Crimes to Victim, Crime to M.O. I need to see

17 Accidental GIS Geocoded Traffic Citations and Accident Report Data Day of Week, Time of Day, Surrounding Land Uses Are All Looked at Impacts Traffic Patrol, Traffic Management Center/City Engineering Efforts # of Traffic Crashes Intersection Mid-Block

18 Ups and downs in traffic patrol

19 GIS goes Over the Limit Off- and On-System Radar Permits merged with road data Available to Traffic Patrol Units via ArcExplorer on MDTs

20 Internet crimes Generation II ArcGIS Server Web Service Coming in 07

21 CAR 54, Where Are You? New & Improved In-Car GIS Layers AVL System + ArcObjects = Familiar Look with Increased Functionality 620 Ledgedale Cir. My Location Spatial Query Buffer Tool Aerial Images Prototype in PD Results will be posted here

22 The long arm is reaching out with GIS Accurate dispatch of emergency services Effective use of people & resources Illuminate patterns/trends Satisfies public information requests with less manpower IF Efficient and informed police service = Less Crime THEN Good for Economic and Community Development
