Dear TawhidAhmad, I'm afraid the quality of your contributions has not improved since I commented on an edit of yours in https://www.openstreetmap.org/changeset/144954530 - you are now labelling your edits a "quick flythrough of arterial roads" without even mentioning that this is 100% sidewalk mapping.

If you must map sidewalks in residential neighbourhoods, at least try not to create work for other mappers.
