Design of Geographic Information Systems to Promote Accessibility and Universal Access

Abstract

Digital systems and solutions providing location based services for everyday activities are supported by geographic information systems that are typically problem-oriented. Although recently some approaches try to combine data from multiple sources to provide a better user experience, most often than not, these extra sources of input are not meaningful and act merely as an extension or augmentation of the user’s physical context, providing extra data that not always adds extra value to the service. In this work, a geographic information system that provides valuable data for multiple audiences, with different restrictions and requirements, is presented. This work also presents the concept of ‘awareness’, implemented using a hierarchical layering system. Using lists of information layers, together with an appropriate categorization of user requirements, the proposed information system can feed different final applications with different data, for different types of users, promoting accessibility and universal access. © Springer International Publishing AG 2017.
