标题：Improving an outreach service by analyzing the relationship of health information disparities to socioeconomic indicators using geographic information systems
摘要：The use of geographic information systems (GIS) with US Census data provides libraries with the power to combine, analyze, and present information in new ways. GIS is a valuable tool capable of “capturing, storing, analyzing, and displaying geographically referenced information” [1]. GIS software combines maps with layers of associated data to provide a visual picture that allows greater understanding and analysis than static figures and tables. Although the software was expensive in the past, GIS has become increasingly more affordable for libraries since it has become available in web-based applications, including open source options [2].
