The Open Geospatial Consortium (OGC) is an international consortium of more than 250 companies, agencies, and universities participating in the development of publicly available conceptual solutions that can be useful with all kinds of applications ...This term refers to an SQL environment that has been extended with a set of geometry ...
https://dev.mysql.com/doc/refman/8.0/en/spatial-relation-functions-object-shapes.html
Functions in this section detect arguments in either Cartesian or geographic spatial reference systems (SRSs), and return results appropriate to the SRS. If any geometry argument is a syntactically well-formed geometry in an undefined spatial ...

For InnoDB and MyISAM tables, MySQL can create spatial indexes using syntax similar to that for creating regular indexes, but using the SPATIAL keyword. For storage engines that support nonspatial indexing of spatial columns, the engine creates a ...The table also has an AUTO_INCREMENT column fid for storing object ID ...

srs_attribute: { NAME 'srs_name' | DEFINITION 'definition' | ORGANIZATION 'org_name' IDENTIFIED BY org_id | DESCRIPTION 'description' } srid, org_id: 32-bit unsigned integer This statement creates a spatial reference system (SRS) definition and ...
https://dev.mysql.com/doc/refman/8.0/en/spatial-type-overview.html
MySQL has spatial data types that correspond to OpenGIS classes. Some spatial data types hold single geometry values: GEOMETRY POINT LINESTRING POLYGON GEOMETRY can store geometry values of any type. The other spatial data types hold collections of ...The basis for these types is described in Section 13.4.2, “The OpenGIS Geometry ...

A spatial reference system (SRS) for spatial data is a coordinate-based system for geographic locations. There are different types of spatial reference systems: A projected SRS is a projection of a globe onto a flat surface; that is, a flat map.
https://dev.mysql.com/doc/refman/8.0/en/optimizing-spatial-analysis.html
For MyISAM and InnoDB tables, search operations in columns containing spatial data can be optimized using SPATIAL indexes. The most typical operations are: Point queries that search for all objects that contain a given point Region queries that ...
https://dev.mysql.com/doc/refman/8.0/en/spatial-function-argument-handling.html
Spatial values, or geometries, have the properties described in Section 13.4.2.2, “Geometry Class”. Each geometry value is associated with a spatial reference system (SRS), which is a coordinate-based system for geographic locations. The ...
https://dev.mysql.com/doc/refman/8.0/en/spatial-index-optimization.html
MySQL permits creation of SPATIAL indexes on NOT NULL geometry-valued columns (see Section 13.4.10, “Creating Spatial Indexes”). The optimizer checks the SRID attribute for indexed columns to determine which spatial reference system (SRS) to ...

These functions support all argument type combinations except those that are inapplicable according to the Open Geospatial Consortium specification. If any geometry argument is a syntactically well-formed geometry in an undefined spatial reference ... OpenGIS proposes a number of functions that can produce ...
