gepaf

The goal of gepaf is to encode and decode the Google Encoded Polyline Algorithm Format.

Example

Encoding

library(gepaf)
coords <- data.frame(
  lat = c(38.5, 40.7, 43.252),
  lon = c(-120.2, -120.95, -126.453)
)
encpoly <- encodePolyline(coords)
encpoly

Decoding

coords <- decodePolyline(enc_polyline = "_p~iF~ps|U_ulLnnqC_mqNvxq`@")
coords
