The map atlas is a systematic collection of spatial data and is designed to simplify the transition between overlapping data of different scale. The training film shows the technology of forming the Atlas of maps using the example of the Russian Federation's base map of scale 1: 1 000 000 and maps of subjects of the Russian Federation of scale 1: 25 000.
The digital thematic (geographical) map of Russia on the scale of 1: 1 000 000 provides an overview of the country territory, but its composition does not provide detailed data on the subjects of the Russian Federation. Free maps based on OpenStreetMap data of scale 1: 25 000 contain detailed information on the objects of the terrain.
When combining spatial data in the Map Atlas, the operator sets the visibility ranges (displaying) for each set and determines their numerical composition, which allows to exclude unused data. The transition is performed using the geodetic coordinates of the cursor or the center of the active window. The map atlas is presented as a tree of a group of projects. The group of projects includes various types of data - vector, raster and matrix maps, as well as map projects (MPT).
