This paper outlines the roadmap and the preliminary results of an interactive systems aimed at providing interactive urban maps tailored to people with Autism Spectrum Disorder (ASD). It aims at involving ASDs in the design process to produce personalized services that can support their daily movements and task management, improving their autonomy and sense of agency.

Maps are being widely used as tools for presenting or retrieving information with spatial attributes. Existing mapbased applications do not use the full potential of digital maps and geographical data: social media are disconnected from the underlying geographical entities; maps as visualization tools do not use the urban topology to cluster point of interest; maps as input systems are intrinsically ambiguous. This work presents a topology-aware indexing system supporting a new metaphor for a real integration between social media and digital maps. The methodology and technical solutions required to build and populate the indexing table starting from OpenStreetMap spatial primitives are introduced.
