Union of objects

This mode is intended for uniting polygon objects, in which the values of semantics coincide. Thus, only polygon objects of the type specified in the dialog, which are located on one sheet of the map, are processed.

The procedure for working with the dialog is as follows:

- select the required map from the list of maps;

- make a list of semantics, by which values the uniting will be made;

- select the type of source objects;

- select the type of the resulting objects;

- click «Run» button.

Formation of the semantics list is made using the buttons «+» and «-». Addition into the list two times of same semantics is not provided. The execution of the task can be interrupted by the «Exit» button, which during the execution turns into the «Cancel» button. The result of the work are the newly created objects. If the source objects did not touch each other, and there is no possibility to unite them, they will be added to the resulting object as the multipolygon contours. It is desirable that the source objects were simple (not multipolygons), otherwise after execution, it is possible that not all the contours of the source multipolygon object will be added to the resulting object.
