Placemark Releases New Polyline Library
Polylines are an efficient way to represent line geometries. You provide a geometry, and out comes a scrambled string of letters and numbers that encodes the geometry in just a few characters. Polylines are helpful when you want to efficiently transfer geometry information between services. The Mapbox Static Images API, for example, can overlay complex geometries from Polylines, which wouldn’t be possible otherwise because the request-URL length is limited.
