Pre-General Availability Draft: 2017-09-22
table provides information about available spatial reference
systems for spatial data. This table is based on the SQL/MM
(ISO/IEC 13249-3) standard. MySQL implements
ST_SPATIAL_REFERENCE_SYSTEMS as a
view on the
The spatial reference system name. This value is unique.
The spatial reference system numeric ID. This value is unique.
SRS_IDvalues represent the same kind of values passed as the SRID argument to spatial functions.
SRID 0 is special. It is always a legal spatial reference system ID and can be used in any computations on spatial data that depend on SRID values. However, SRID 0 has no entry in
ST_SPATIAL_REFERENCE_SYSTEMSbecause it cannot be described by the SRS definition format. It represents an infinite flat Cartesian plane with no units assigned to its axes. Unlike projected SRSs, it is not georeferenced and it does not necessarily represent Earth. It is an abstract plane that can be used for anything.
The name of the organization that defined the coordinate system on which the spatial reference system is based.
The numeric ID given to the spatial reference system by the organization that defined it.
The spatial reference system definition, as a WKT value.
The spatial reference system description.
DESCRIPTIONcolumns contain information that may be of interest to users, but they are not used by MySQL.
