Well-known text representation of coordinate reference systems (WKT or WKT-CRS) is a text markup language for representing spatial reference systems and transformations between spatial reference systems. The formats were originally defined by the Open Geospatial Consortium (OGC) and described in their Simple Feature Access[1] and Well-known text representation of coordinate reference systems[2] specifications. The current standard definition is ISO 19162:2019.[3] This supersedes ISO 19162:2015.[4]
