Overview Maps

Overview maps are auxiliary graphic data enabling orientation in the geographic space of the project. Any number of overview maps can be defined in one project. In fact, an overview map is a set of backdrop maps with a spatial restriction. Different spatial areas of the same backdrop map may, thus, represent different overview maps within a project. The overview maps definitions are grouped together in the vicinityMapArray collection.
