Geographic information systems are a universal source of up-to-date information about the region. Moreover, this information is heterogeneous (from spatial data to descriptive data) and is used when making decisions by all possible stakeholders: economic partners, enterprises, other regions, e-government. In this regard, the urgent task is to make a decision on regular updating of the GIS, based on various factors (from technical to economic, socio-cultural and organizational). To automate and simplify this task we propose a method and a corresponding decision support software service for linguistic multi-criteria choice among multiple design alternatives. Our method and prototype are based on a hierarchy of cross-disciplinary criteria and ontology-based mechanisms (for the dynamic GUI customization) which reflect the concept of crisisology.
