Functions

decodePolyline(String polyline, {int accuracyExponent = 5}) → List<List<num>>

Decodes polyline String via inverted Encoded Polyline Algorithm

encodePoint(num current, {num previous = 0, int accuracyExponent = 5}) → String

Polyline encoding is a lossy compression algorithm that allows you to store a series of coordinates as a single string. Point coordinates are encoded using signed values. If you only have a few static points, you may also wish to use the interactive polyline encoding utility.

encodePolyline(List<List<num>> coordinates, {int accuracyExponent = 5}) → String

Encodes List<List<num>> of coordinates into a String via Encoded Polyline Algorithm Format
