This section introduces the ISO standards in LongitudeOne's spatial reference scope:

• ISO/IEC 13249-3 — SQL/MM Spatial;
• ISO 19107:2019 — Spatial schema (OGC 19-092);
• ISO 19111 — Referencing by coordinates;
• ISO 19136 — Geography Markup Language.

The references identify the assessed editions, requirements and LongitudeOne support, limitations and extensions. Inclusion here does not imply support or conformance.
