Well-Known Text (WKT) is a text markup language used to represent geometric objects on a map. It provides a simple way to describe shapes like points, lines, and polygons in a human-readable format. WKT is commonly used in geographic information systems (GIS) and spatial databases to facilitate the exchange of spatial data. WKT is part of the Open Geospatial Consortium standards, which aim to promote interoperability in geospatial data. By using WKT, developers and analysts can easily share and manipulate geometric data across different software applications, ensuring consistency and accuracy in spatial analysis.
