MySQL Error 3521: Cartesian SRS Required, SRID Undefined
Description
This error indicates that a spatial function, which specifically requires a Cartesian (planar) spatial reference system, was called with an argument belonging to an undefined or incompatible SRID. It typically occurs when MySQL cannot find the definition for the specified SRID or when the SRID is not recognized as Cartesian for the function's context.
Error Message
Function %s is only defined for Cartesian spatial reference systems, but one of its arguments is in SRID %u, which has not been defined.
Known Causes
3 known causesUndefined SRID
The Spatial Reference System Identifier (SRID) associated with the spatial data argument is not defined within MySQL's internal registry of spatial reference systems.
Incorrect SRID Type
A spatial function requiring a Cartesian (planar) coordinate system received data from a geographic (e.g., latitude/longitude) or an unrecognized projected SRID.
Missing SRS Definition
The necessary entry for the SRID in the `ST_SPATIAL_REFERENCE_SYSTEMS` table is absent or incorrectly configured.
