#1751 issue: add Filter polyline

[adityakishor1]

To filter a PolyLine, you'll need to define what you mean by "filter." Here are a few common methods for filtering Polylines:

Filter by length: You can filter Polylines based on their length. For example, you might want to keep only Polylines that are longer than a certain threshold, or you might want to remove Polylines that are shorter than a certain threshold.

Filter by proximity: You can filter Polylines based on their proximity to other features or locations. For example, you might want to keep only Polylines that are within a certain distance of a particular point or feature.
