Objektivńı hodnoceńı atraktivity region̊uOtakar Čerba; Sarah Velten; Jan Macura; Viktorie SloupováWhen looking at maps that visualize large amounts of heteroge-neous data, questions often arise: why was this particular inputdata chosen, or are all input data equally important. There aremany challenges associated with spatial visualization, and thesechallenges have no clear-cut solution. The outcome often de-pends on the individual user’s perspective and subjective under-standing of the problem. Reflection of users’ needs is the reasonfor developing interactive web maps. These allow the users tochoose input parameters that suit their needs. The architectureof the web map appliation interconnects four crucial compo-nents: map client for data visualization, robust tool for mathe-matical operations to process data, input datasets and ontologyto define essential semantic relations among stakeholders, theirrequirements and input data. The role of the ontology is tospecify relations among types of stakeholders, tasks typical forvarious types of stakeholders and datasets relevant for this task.Except for the formalization of relations, the ontology makes theapplication user interface accessible for non-experienced users.The reasoning process is the main benefit of the implemen-tation of ontology. The reasoner can check the consistency ofthe ontology, detect errors and add missing relations. For thesepurposes, the reasoner uses formal and formalized descriptionsof the system’s components and Description Logic principles.This solution was developed in the Polirural project to assess25pilot regions and compare pilot regions with the rest of Europe.The application uses HSLayers as the map client interconnectedwith the R script to calculate the index of attractiveness andclusters of homogeneous regions. The ontology of stakeholders’roles and relevant datasets is implemented as data input forthe interactive user interface. The application uses only open-licenced components.Authors was supported by the project Polirural26
