clojure-polyline

Decoding and encoding of the google polyline algorithm as described at https://developers.google.com/maps/documentation/utilities/polylinealgorithm

usage

[com.michaelgaare/clojure-polyline "0.2.0"]

(require com.michaelgaare.clojure-polyline :as polyline)

Decode a polyline string:

(polyline/decode polystring)

Returns a vector of maps: [{:latitude long :longitude long} ...]

Encode a vector of coordinates:

(polyline/encode coords)

returns a polyline-encoded string

-- encode expects a sequence of vectors of the format [latitude longitude] - if you have this as a sequence of maps of the format {:longitude longitude :latitude latitude} you can use (coords->vec) to turn it into the right format.

• you can use to-coords to turn a vector of [latitude longitude] vectors into this format)
