Cadastral maps are essential component of cadastral documentation. They are heterogeneous from many points of view and have several dissimilarities and imperfections. Only one half of them has been created in actual mapping campaign, thus with quality criteria which are sufficient for current requirement of modern society. The fact, that maps are in vector form, does not guarantee their accuracy and quality. The user must be extremely cautious when a digital image of the map is interpreted. The advances in technology and the availability of GIS tools open wide range of spatial data analysis. Vector cadastral maps represent a structured spatial database that also includes information about positional accuracy of each detailed survey point. This information is a key element that can be utilized. The quality of detailed survey point determines the quality of the boundary and the quality of position of the particular location on the map. The article presents a spatial analysis of the vector cadastral map accuracy. Visualization quickly highlights the areas with specific reliability of positional accuracy. Results of spatial analysis focused on accuracy are for vector cadastral maps users significant.

Keywords: detailed survey point, vector cadastral map, positional accuracy, spatial
