Filtering objects

Filtering allows to delete superfluous vertexes (located on one straight line or nearly so on one straight line). The degree of a filtration is conditioned by value of a filtering level in dialog: Map Editor options.  

For an execution of a filtering it is necessary to choose edited object.

The coordinated filtering of the chosen object carries out a filtering of points of the metrics of object not breaking its topological coordination with the next objects (borders of all objects are filtered, being the common with chosen one).
