Geographical Accessibility to Primary Care Health Facilities in Oklahoma

Geographical accessibility measures the ease with which people can reach desired services, such as healthcare facilities. It is an important aspect of health geography and urban planning, as it influences both policy decisions and resource allocation. This case study demonstrates the application of the GIScience Worklfow Management System (WfMS) to analyze geographical accessibility to primary care health facilities in Oklahoma. By integrating three spatial analysis models (2SFCA, E2SFCA, and G2SFCA) into a single workflow, users can efficiently compare and interpret the accessibility measures. This case study involves 7 different nodes: CsvReader, GeoFileReader, 2SFCA, E2SFCA, G2SFCA, RenameFileName, and GeoFileViewer.

地理可达性（Geographical Accessibility）指民众抵达医疗设施等所需服务的便捷程度。其作为健康地理学与城市规划的重要研究维度，对政策决策与资源配置均具有重要影响。本案例研究展示了地理信息科学工作流管理系统（GIScience Workflow Management System，WfMS）在俄克拉荷马州基层医疗卫生机构地理可达性分析中的应用。通过将2SFCA、E2SFCA与G2SFCA三种空间分析模型整合至单一工作流中，用户可高效对比并解读各类可达性评估指标。本案例研究共包含7类工作流节点：CsvReader、GeoFileReader、2SFCA、E2SFCA、G2SFCA、RenameFileName以及GeoFileViewer。
