A MultiPoint is a geometry collection composed of Point elements. MultiPoint Examples On a world map, a MultiPoint could represent a chain of small islands. On a city map, a MultiPoint could represent the outlets for a ticket office. A MultiPoint ...
https://dev.mysql.com/gis-data-formats.html
MySQL uses values from 1 through 7 to indicate Point, LineString, Polygon, MultiPoint, MultiLineString, MultiPolygon, and GeometryCollection. MySQL supports geometry types of Point, LineString, Polygon, MultiPoint, MultiLineString, MultiPolygon, and ... Two standard spatial data formats are used to represent geometry objects in queries: Well-Known Text (WKT) format Well-Known Binary (WKB) format Internally, MySQL stores geometry values in a format that is not identical to either WKT or WKB ...
https://dev.mysql.com/spatial-convenience-functions.html
These convenience functions are available: ST_Distance_Sphere(g1, g2 [, radius]) Returns the mimimum spherical distance between Point or MultiPoint arguments on a sphere, in meters. If both geometry parameters are valid Cartesian Point or MultiPoint ... The functions in this section provide convenience operations on geometry ...
https://dev.mysql.com/spatial-operator-functions.html
These arguments are byte string values produced by the ST_Buffer_Strategy() function, to be used for point, join, and end strategies: Point strategies apply to Point and MultiPoint geometries. ST_Buffer() handles its arguments as described in the ...
https://dev.mysql.com/func-op-summary-ref.html
GTID_SUBTRACT() Return all GTIDs in set that are not in subset. JSON_CONTAINS() Whether JSON document contains specific object at path JSON_CONTAINS_PATH() Whether JSON document contains any data at path JSON_DEPTH() Maximum depth of JSON document ...
https://dev.mysql.com/gis-wkt-functions.html
Functions such as ST_MPointFromText() and ST_GeomFromText() that accept WKT-format representations of MultiPoint values permit individual points within values to be surrounded by parentheses. For example, both of the following function calls are ...
https://dev.mysql.com/spatial-function-reference.html
The following table lists each spatial function and provides a short description of each one.
https://dev.mysql.com/gis-geometry-class-hierarchy.html
The geometry classes define a hierarchy as follows: Geometry (noninstantiable) Point (instantiable) Curve (noninstantiable) LineString (instantiable) Line LinearRing Surface (noninstantiable) Polygon (instantiable) GeometryCollection (instantiable) ...All classes have properties, and instantiable classes may also have assertions (rules that define valid class ...
https://dev.mysql.com/spatial-relation-functions-object-shapes.html
Prior to MySQL 8.0.18, the only permitted geographic argument types are Point and Point, or Point and MultiPoint (in any argument order). ST_Touches() handles its arguments as described in the introduction to this section except that the return ...
https://dev.mysql.com/gis-class-geometry.html
Geometry values of types (LineString, MultiPoint, MultiLineString) are either simple or nonsimple. The dimensions of MultiPoint, MultiLineString, and MultiPolygon objects are the same as the dimensions of the elements they consist of. It is a ...
