Sažetak
The spatial distribution of the population at a higher level of detail is a useful tool for decision-making in the planning and management process, as well as in numerous socio-economic researches. Dasymetric modeling ia s technique for redistribution of population data from census- designated administrative units into raster data with higher spatial resolution. The main aim of this paper is to apply different geospatial technologies to create a very high-resolution dasymetric model at the level of individual buildings. A new proposed methodology for mapping of population within IB integrates and synthesizes data from different sensors. This paper describes in detail the steps that lead to the identification of buildings using a multi- data/sensor approach. The building footprints were extracted using geographic object-based image analysis, based on the created multispectral model. Heigh data and shape of buildings were obtained by collection and processing of aero- LiDAR data using the artificial intelligence tools. To generate a better model, spatial plan data were used, which enabled the classification of buildings into residental and non-residental ones. Residental buildings were further classified into houses and buildings. The accuracy of the created model was tested using the area under curve measure based on the reference data. The applied approach and obtained data can be used to solve a number of problematic issues, such as characterization of the population at risk from natural hazards and assessing human induced pressure on the environment.
