Trust in Web GIS

Crime Incidents in London



Attesting to the powerful capabilities and in technology trends, many scholars envisioned the consolidation of Geographic Information Systems (GIS) into vital tools for disseminating spatial information, that are presently used to inform, advise and instruct users in several contexts and to further engage citizens in decision-making processes that can impact and sustain policy development. Interaction with these applications incorporates risk and uncertainty, which have been repeatedly identified as preconditions in nurturing trust perceptions, and which instigate a user’s decision to rely on a system and act on the provided information.

In a four-year project carried out in collaboration with Arup and with the support from the UK Engineering and Physical Sciences Research Council (EPSRC), Artemis Skarlatidou, used a multidisciplinary research approach derived mainly from the fields of Human-Computer Interaction and Risk Communication, to identify how non-experts' trust perceptions are formed when they interact with environmental Web GIS applications, but also how information about nuclear waste should be communicated to lay people to improve public understanding and trust. The findings supported the development of the PE-Nuclear tool; a Web GIS application to inform lay people in the UK about the site selection of a nuclear waste repository. 

In a different project, also funded by the UK Engineering and Physical Sciences Research Council (EPSRC), we use the same approach to identify how non-experts' trust perceptions are formed when they interact with public crime Web GIS. One part of this research focuses on identifying the user needs and expectations when they interact with different types of crime data at different scales and for different purposes, while the other part aims at building novel crime visualisation approaches which are evaluated for their perceived trustworthiness with non-expert users.
