What is the meaning of WKT (Well-Known Text)?
In geospatial applications, coordinate reference systems and geometric forms are represented using Well-Known Text (WKT), a standardized, human-readable language. It offers a consistent and straightforward method for describing spatial data structures in plain text, including points, lines, polygons, and even intricate geometries. A polygon could be denoted as POLYGON ((30 10, 40 40, 20 40, 10 20, 30 10)) and a point as POINT (30 10). In order to facilitate consistent understanding and interpretation of spatial data across various GIS platforms and databases, WKT is also used to construct spatial reference systems. WKT, which is extensively supported by GIS programs like PostGIS, QGIS, and ArcGIS, is essential for facilitating data interchange and interoperability among diverse applications and systems.
