| Online overview | https://www.iso.org/obp/ui/#iso:std:iso:19125:-2:ed-1:v1:en |
| Type of standard | ISO International Standard Meta level |
| Application | Part two of ISO 19125 specifies an SQL schema that supports storage, retrieval, query and update of simple geo-spatial feature collections. |
| Conformance classes | SQL SQL with Geometry Types |
| Implementation benefits | ISO 19125-2 standardizes the names and geometric definitions of the SQL Types for the Geometry class, and names, signatures and geometric definitions of the SQL Functions for Geometry. The implementation of ISO 19125-2 is an extension of SQL and is very simple to use. This extension of SQL is a very effective method of querying a database or performing complex analysis. |
| Products | Two popular implementations of ISO 19125-2 are PostGIS (an extension of PostgreSQL) and Oracle Spatial. |
