In gepaf: Google Encoded Polyline Algorithm Format

Description

Encode a data.frame of coordinates to a Google polyline.

Usage

encodePolyline(df_coords, factor = 5)

Arguments

df_coords	a data frame of coordinates with two columns: latitudes and longitudes. Coordinates must be in decimal degrees (WGS84).
factor	number of decimal digits to be used.

Value

An encoded polyline is returned.

Examples

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

Example output

[1] "_p~iF~ps|U_ulLnnqC_mqNvxq`@"
