Well-Known Text (WKT) is a standardized text representation used in geospatial data to describe geometric objects, such as points, lines, and polygons. It provides a human-readable and compact way to convey the spatial properties of these objects. WKT is particularly useful for exchanging geospatial data between different systems and applications, ensuring that geometry information remains consistent across platforms.
In a WKT representation, a geometric object is defined by specifying its type (e.g., POINT, LINESTRING, POLYGON) followed by the coordinates that define its shape and location. For example, a simple POINT in WKT might look like this: "POINT(45.6789 -123.4567)". This tells us that there is a single point located at latitude 45.6789 and longitude -123.4567.
WKT is not only easy for humans to read but also straightforward for software to parse and interpret, making it a valuable tool for geospatial data exchange, storage, and analysis. Whether you're working with geographic information systems (GIS), databases, or web applications, WKT is a common format used to represent spatial data accurately and consistently.
