Abstract
Mapping of the population with high resolution of images alleviates the investigation of the urban environment, while cur rently relevant information problems have been actively discussed, such as the poor spatial inhomogeneity of alternative data, and the quality of traditional (usually outdated and inaccurate) data on the population of the territory. The technique was de veloped for compiling population localization and mobility. Data received from mobile telephones can be displayed in real time as well as enhancing the spatial inhomogeneity of users. Based on the geographical location of base stations, it is possible to analyze the density of users at a particular time at a particular point. Using results of spatial analysis as a basis, we obtained the density of signals for a specific time interval. However, the geographical range of users recorded via mobile telephone by base stations do not have any fixed spatial boundary. To solve this problem we compiled the Voronoi polygons for the base stations.
