WV Division of Rehabilitation Services
Purpose•Introduce GIS (ArcGIS: ArcMap 10) as a
tool to pinpoint parts of West Virginia where populations are potentially unserved and possibly underserved by WVDRS
•Discuss other mapping tools in VR
7WV Division of Rehabilitation Services
Goal
•Improve planning for community outreach efforts▫Cost-effective method to increase
awareness of WVDRS programs and services among VR stakeholders and consumers

Identification of Potential Underserved and Unserved Areas
Summary of Steps
9WV Division of Rehabilitation Services
Step 1. Determine scale for potential underserved and unserved areas (geographic area)Possible scales
*Proposed RSA-911 requires VR agencies to report zip code information 10

•Potential Unserved Zip Codes▫Ø active clients
•Possible Underserved Zip Codes▫Number of active clients below the state
average, as of 5-18-2011 Avg: 44.94

Summary• GIS application in VR• Improve planning for community outreach efforts
• Other GIS Possibilities for State VR Agencies▫ Aid in matching employment needs of clients with available
jobs Match case management records with local employment
dynamics data (U.S. Census)▫ Help find the most suitable location for a new branch office
Spatial Analyst Extension in ArcGIS Input model criteria to define best location: Cost; accessibility;
terrain; etc.▫ Explore patterns of success in employment outcomes
Explore by district office or branch office Map best performers in terms of successful and unsuccessful
closure statuses: Model performance (Logistic regression or discriminant
function analysis) using data from case management records and quality assurance review
Use results to mark areas where improvements could be made30WV Division of Rehabilitation
