Work with objects from lists

This mode is designed for working with objects from list files.

The following are selected for operation: a map for placing the result, two lists of objects (preferably different ones), the type of operation to be performed (intersection, union, union of intersections), and the types of resulting objects.

The outcome of the operation is newly created objects, formed in a specific manner.

When creating objects of the Intersection type, the output object will be one created by the intersection of an object from the 1st list with an object from the 2nd list.

The resulting object will be of the following type:

• When intersecting two area objects — an area object.

• When intersecting an area object and a linear object — both an area and a linear object.

• When intersecting two closed linear objects — two unclosed linear objects.

• When intersecting two unclosed linear objects — no resulting object will be created.

When creating objects of the Union type, the outputs will be objects from both lists, wherein intersecting or touching objects will be merged into one. Only area objects are processed.

When creating objects of the Union of Intersections type, the outputs will be objects obtained first by intersecting objects from the 1st list with objects from the 2nd list, and then the intersecting or touching objects will be merged into one.
