1.23 OGC and ISO Compliance

Oracle Spatial is conformant with Open Geospatial Consortium (OGC) Simple Features Specification 1.1.1 (Document 99-049), starting with Oracle Database release 10g (version 10.1.0.4).

Conformance with the Geometry Types Implementation means that Oracle Spatial supports all the types, functions, and language constructs detailed in Section 3.2 of the specification.

Synonyms are created to match all OGC function names except for X(p Point) and Y(p Point). For these functions, you must use the names OGC_X and OGC_Y instead of just X and Y.

Oracle Spatial is conformant with the following International Organization for Standardization (ISO) standards:

• ISO 13249-3 SQL Multimedia and Application Packages - Part 3: Spatial

• ISO 19101: Geographic information - Reference model (definition of terms and approach)

• ISO 19109: Geographic information - Rules for application schema (called the General Feature Model)

• ISO 19111: Geographic information - Spatial referencing by coordinates (also OGC Abstract specification for coordinate reference systems)

• ISO 19118: Geographic information - Encoding (GML 2.1 and GML 3.1.1)

• ISO 19107: Geographic information - Spatial schema (also OGC Abstract specification for Geometry)

However, standards compliance testing for Oracle Spatial is ongoing, and compliance with more recent versions of standards or with new standards might be announced at any time.
