Background on GIS What is it? How does it work? What are the benefits? Who uses GIS? What is it used for? 3 WV Division of Rehabilitation Services

What is GIS? How Does it Work? GIS?Data Sources A system designed to inform decision making from data GIS Satellite Data (Satellite Imaging Corp.) Aerial Photographs (Local Universities) Tabular Information (U.S. Census) Other Digital Data (Political Boundaries: U.S. Census) Digital Maps (City/County Government) 4 WV Division of Rehabilitation Services

What are the Benefits? Benefits?Example: Tabular Data Data ▫Capture ▫Store ▫Manage ▫Display ▫Analyze  Most efficient and effective for VR administrators  Ease with which data can be communicated 5 WV Division of Rehabilitation Services

Who Uses GIS? What is it Used for? Who?Uses? Government Agencies ▫Federal ▫State ▫Local Real Estate Health Care Retail Information Others Federal Government ▫Monitor predatory lending practices State Government ▫Maintain highways and roads Local Government ▫Establish evacuation routes ▫Track local crime patterns Real Estate ▫Track property values and tax information Health Care ▫Track spread of disease Retail ▫Find optimal location for new store ▫Trade Area Information ▫Planning of utility expansion 6 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 7 WV 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 8 WV Division of Rehabilitation Services

Identification of Potential Underserved and Unserved Areas Determine scale that will be used to define areas (geographic area) Create boundary layer for entire service area Join active clients table with GIS boundary layer Operationalize possibly underserved and unserved areas Create map of active cases Summary of Steps 9 WV Division of Rehabilitation Services

Step 1. Determine scale for potential underserved and unserved areas (geographic area) Possible scales District County *Zip Code Census Tract Block Group Block *Proposed RSA-911 requires VR agencies to report zip code information 10 WV Division of Rehabilitation Services

Step 2. Create Zip Code Boundary Layer for State of West Virginia (WVDRS service area) Outline of Step Navigate Network to Find Corresponding Data Source 2.2 Add U.S. Zip Code Layer 2.3 Create WV Zip Code Layer 11 WV Division of Rehabilitation Services
