Comparison with the reference value on the example of gis-based applications

Abstract

The article gives a new approach to the assessment of objects in terms of various criteria which by its nature belong to the issue of multi-criteria decision making and analysis. The proposed variant of multi-criteria decision-making is based on a comparison of the real considered object model that is created according to user’s requirements with the reference value. The geographic object means a real object in this case the object is stored in digital geo-database in the geographic information system (GIS). The reference value represents optimal geographic object which is the most suitable for user’s purposes. The comparison of the values of individual criteria is based on the theory of tolerance and metric spaces. Supplementary GIS-based application to calculate the weights of the criteria, which have served to comparison was used. The proposed procedure for the evaluation of various criteria has been validated on a pilot project “SMART Regions” in the city Brno district of Nový Lískovec neighbourhood in the Czech Republic. Around the city district known by its typical of prefabricated blocks of flats it is necessary to compare the different options for renewal urban housing development. Urbanization city prefabricated housing estates using GIS opportunities will be ready to quick respond to the call of various changes in the field of energy sustainability. Therefore, it is important to utilize the available environmental resources for energy sustainability.
