The improvement of measurement and particularly surveying technologies results in a large as well as rapidly increasing amount of spatial data. These data stem from various measurement techniques as well as platforms and, therefore, may compile quite different densities, qualities, and error characteristics. Effective tools are required to understand and interpret them. The challenges include efficient processing, robustness against data flows and uncertainty, rationality of modeling, and the potential of automation and learning. This thesis presents an exploration of the use of statistical models and related techniques in spatial data analysis. The foundation of the methodology employed in the scope of this thesis consists of Bayesian statistics and Markov models. Selected approaches conceived by the author, including 3D building reconstruction, semantic building classification, pattern recognition in trajectories, and segmentation of RGBD data, demonstrate their potential in spatial data modeling and interpretation.
