Well-known text representation of geometry

"Well-known text" redirects here. For representation of coordinate reference systems, see Well-known text representation of coordinate reference systems.

Well-known text (WKT) is a text markup language for representing vector geometry objects. A binary equivalent, known as well-known binary (WKB), is used to transfer and store the same information in a more compact form convenient for computer processing but that is not human-readable. The formats were originally defined by the Open Geospatial Consortium (OGC) and described in their Simple Feature Access.[1] The current standard definition is in the ISO/IEC 13249-3:2016 standard.[2]
