Well-known Text (WKT) is a text markup language for representing vector geometry objects. It's a human-readable text format that allows for the representation of geometric shapes like points, lines, polygons, and more complex geometries such as MultiPoint, MultiLineString, and MultiPolygon. WKT is primarily used in geographic information systems (GIS), databases, and other applications that deal with spatial data. It provides a standardized way to exchange and store geometric data, ensuring interoperability between different systems. The format specifies how to encode geometric objects as strings, making it easy to parse and interpret the data. WKT is a core component of the Open Geospatial Consortium (OGC) standards and is widely supported by various GIS software packages and database systems with spatial extensions. The simplicity and readability of WKT make it a popular choice for representing spatial data in configuration files, data exchange formats, and even in database queries.
