Target layer: Polyline

Description:  Drag a selection box. All the polylines completely contained in the selection box will be deleted. The nodes within the selection box will be moved to a single location ( the centroid of the convex polygon formed by all the contained nodes)

Advantages: 

• In many cases due to inaccurate digitizing there are small excessive polyline segments. After intersecting these segments are converted into new polylines that need to be removed from the dataset. This tool automates this cleaning process.
