Application Summary AI generated
This standard defines SQL-based methods for accessing and querying geographic feature data, specifying how spatial data types, functions, and operators are integrated into SQL database systems. It is applied in geographic information systems (GIS) and spatial database management, enabling developers and engineers to store, retrieve, and manipulate vector geometry (e.g., points, lines, polygons) using standard SQL queries. The standard ensures interoperability across platforms for applications like mapping, urban planning, and location-based services.
