Geo.WKB (Geo v3.3.8) View Source
Converts to and from WKB and EWKB.
Examples
iex> {:ok, point} = Geo.WKB.decode("0101000000000000000000F03F000000000000F03F")
Geo.Point[coordinates: {1, 1}, srid: nil]
iex> Geo.WKT.encode!(point)
"POINT(1 1)"
iex> point = Geo.WKB.decode!("0101000020E61000009EFB613A637B4240CF2C0950D3735EC0")
Geo.Point[coordinates: {36.9639657, -121.8097725}, srid: 4326]
