Abstract
The population and information system should contain all the buildings in Finland. Digital and population data services agency is responsible for the building data along with the municipalities. Municipalities are liable for updating and maintaining the data in building and dwelling register (BDR), where the digital and population data services agency receive their building information. The quality and up-to-dateness varies between the municipalities. The main goal of this thesis is to find out if it is possible to analyze the correctness of the registries with spatial methods by using airborne laser scanning data along with data from topographic database and aerial photos. With the data and software used in this thesis, it is possible to analyze the correctness of the registries. The new analysis workflow gives results that are better than with the traditional way of doing the analysis and gives a more accurate state of the registers.Description
