Public services refer to the provision of immaterial (services) as well as physical goods (infrastructures) for the general public. Examples are healthcare facilities like hospitals or medical practices, education infrastructures like schools, retail, and local amenities. The planners of such services must ensure that facilities are provided for all citizens within a reasonable distance, ithat is, traveling time. At the same time, the actual quality of the supply is relatively difficult to measure. A comprehensive analysis requires population data, detailed information about public service infrastructures and their capacities, as well as their accessibility with different means of transport. This chapter demonstrates how geospatial Web applications and analysis tools can support public service planning and how such centrally provided Web applications can increase the transparency and the quality of planning decisions. At the same time, the workload for planners or decision-makers is reduced since they no longer have to spend time on preliminary data search and integration or on building complex analysis methods and models themselves. In this context, the paper introduces three prototypically implemented applications with their provided functionalities and targeted user groups (e.g., policymakers at different levels, public services planners, or citizens). The applied technologies, architectures, relevant data, and services are discussed.
