Description\n-----------\n\nWKB stands for Well-Known Binary, a format for representing geographical and geometrical data.\n\nWKB uses 1-byte unsigned integers, 4-byte unsigned integers, and 8-byte double-precision numbers.\n\n The first byte indicates the byte order. 00 for big endian, or 01 for little endian.\n The next 4 bytes indicate the geometry type. Values from 1 to 7 indicate whether the type is Point, LineString, Polygon, MultiPoint, MultiLineString, MultiPolygon, or GeometryCollection respectively.\n The 8-byte floats represent the co-ordinates.\n\nTake the following example, a sequence of 21 bytes each represented by two hex digits:\n\n``\n000000000140000000000000004010000000000000\n``\n\n It's big endian\n   000000000140000000000000004010000000000000\n It's a POINT\n   000000000140000000000000004010000000000000\n The X co-ordinate is 2.0\n   000000000140000000000000004010000000000000\n The Y-co-ordinate is 4.0\n  * 000000000140000000000000004010000000000000\n\nURL: https://mariadb.com/docs/server/reference/sql-statements/geometry-constructors/wkb/well-known-binary-wkb-format
