This section describes how to present cellular network data on the map.

Briefly stated, in order to present data, you use presentation layers and fill these with themes. A set of presentation layers is already supplied in the application. Therefore, to get started with presenting data, you do not need to worry about handling presentation layers; all your work is to do with themes and is covered in the present section. However, you can also modify presentation layers and create new ones. How to do this is described in section "Layers".
