hai Thank You. U r right its a gps tracking. Inorder to show the travelled path correctly for a particular duration I need to take all those points. The lat and long points are fetching from the database. So i think if I try to reduce the decimal points, its again load to the server and also if i reduce the number of points the polyline path will not be correct when disaply on the Gmap.
