Geo v3.3.7 Geo.WKB View Source

Converts to and from WKB and EWKB

{:ok, point} = Geo.WKB.decode("0101000000000000000000F03F000000000000F03F")
Geo.Point[coordinates: {1, 1}, srid: nil]

Geo.WKT.encode!(point)
"POINT(1 1)"

point = Geo.WKB.decode!("0101000020E61000009EFB613A637B4240CF2C0950D3735EC0")
Geo.Point[coordinates: {36.9639657, -121.8097725}, srid: 4326]
