Geo.WKB

Summary
Functions

Converts to and from WKB and EWKB

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]
