flexpolyline: Flexible Polyline Encoding

Description

logo

Binding to the C++ implementation of the flexible polyline encoding by HERE https://github.com/heremaps/flexible-polyline. The flexible polyline encoding is a lossy compressed representation of a list of coordinate pairs or coordinate triples. The encoding is achieved by: (1) Reducing the decimal digits of each value; (2) encoding only the offset from the previous point; (3) using variable length for each coordinate delta; and (4) using 64 URL-safe characters to display the result.
