View Source Geo.WKT (Geo v4.0.1)

Converts to and from WKT and EWKT

Examples

iex> {:ok, point} = Geo.WKT.decode("POINT(30 -90)")
Geo.Point[coordinates: {30, -90}, srid: nil]

iex> Geo.WKT.encode!(point)
"POINT(30 -90)"

iex> point = Geo.WKT.decode!("SRID=4326;POINT(30 -90)")
Geo.Point[coordinates: {30, -90}, srid: 4326]
