information . The following is a list of GIS needs and uses as it relates population and demographic tasks : • Demographic and population trend Mapping • Land use analysis , especially rural to urban conversion and development in sensitive areas • Level of Services and Service Area Analysis • Current agriculture tracts • Citizen outreach for specific populations Service Area Analysis GIS should be utilized to evaluate the 'geography" of County facilities, County services , natural resources , and agricultural operations. The distribution of people within the County in relation to County facilities, services , and land should qualify the expressed needs of the community. GIS will analytically and scientifically highlight those parts of the County on which each division should target and/or expand its services and activities . Providing community facilities and services in the right place and at the right time is a continual challenge for many counties and local governments . GIS tools and strategies are now offering both technical and non-technical staff with the opportunity to provide better information to guide the decision making process for solutions that are equitable and meet a defined need . GIS should be used to address : a ) standards based on population , drive times to facilities and properties , distance to customers , and ( b ) service areas to identify " gaps " in the County that may become target areas for additional resources . This analysis includes building a GIS inventory of facilities, mapping population data as a market for services, calibrating population to facility/property use , and developing predictors about future use . Service areas are identified and target areas identified using geo-spatial techniques . Service areas are identified using " buffers " or concentric rings (ring study) . GIS will therefore offer the Department of General Services advanced planning tools and capabilities to improve the delivery of general services and facilities . Service area analyses will require spatial overlay capabilities as depicted in the following graphic : Point Buffers + + Linc 4 Buffers i 2 3 Pokeon But CD] Population trends and demographics of a region are critical for the planning of facilities and services . Equally, travel or " drive " times are a major factor in the use of facilities and services . For example , research indicates that a majority of library users live within a certain distance 125 GIS Needs Assessment and Implementation Plan Chapter I - Departmental GIS Needs Assessment
