Investigation of spatial density of public and business objects in the largest city with help of geoinformation technologies

The article reveals the study of spatial distribution of the density of public and business objects with the use of geoinformation technologies. The source of the data was data from the open geoinformation project OpenStreetMap. Earlier, we showed that for the radial component of the density of public and business facilities. This paper is a continuation of the previous one. The angular distribution of density of public and business objects is studied by example of the largest city - Ekaterinburg. Spatial density has "tails" that characterize the predominant directions of the city development. At the same time, the average spatial configuration for the average density distribution shows the radial-ring structure for urban planning. The obtained results are interpreted within the framework of the "frame-fabric".
