Application level

Application WKB is defined in ISO/IEC 13249-3:2011. WKB is a hexadecimal encoding that can be used to define geometry. Geometries are expressed as a stream of bytes that is not human readable. The type of geometry is specified followed by the coordinates of the nodes.
Implementation benefits In ISO 19125-2:2004 Geographic information - Simple feature access - Part 2: SQL option, WKB is an option of describing geometries. This is an optimal format for databases, since the geometry is expressed as a stream of bytes and can easily be exchanged. However, the encoding does not support any analysis, such as measurements.
