13.4.11 Using Spatial Indexes

https://dev.mysql.com/doc/refman/8.0/en/using-spatial-indexes.html

The following query finds all objects that are in the given rectangle: mysql> SET @poly = -> 'Polygon((30000 15000, 31000 15000, 31000 16000, 30000 16000, 30000 15000))'; mysql> SELECT fid,ST_AsText(g) FROM geom WHERE -> ... The optimizer ...

14.16.5 MySQL-Specific Functions That Create Geometry Values

https://dev.mysql.com/doc/refman/8.0/en/gis-mysql-specific-functions.html

MultiPolygon(poly [, poly] ...) Constructs a MultiPolygon value from a set of Polygon or WKB Polygon arguments. Polygon(ls [, ls] ...) Constructs a Polygon value from a number of LineString or WKB LineString arguments. MySQL provides a set of ...

13.4.2.1 The Geometry Class Hierarchy

https://dev.mysql.com/doc/refman/8.0/en/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 ...

14.16.7.1 General Geometry Property Functions

https://dev.mysql.com/doc/refman/8.0/en/gis-general-property-functions.html

The functions listed in this section do not restrict their argument and accept a geometry value of any type. Unless otherwise specified, functions in this section handle their geometry arguments as follows: If any argument is NULL, the return value ...

14.16.7 Geometry Property Functions

https://dev.mysql.com/doc/refman/8.0/en/gis-property-functions.html

For example, the ST_Area() polygon function returns NULL if the object type is neither Polygon nor MultiPolygon. Each function that belongs to this group takes a geometry value as its argument and returns some quantitative or qualitative property ...

13.4.7 Populating Spatial Columns

https://dev.mysql.com/doc/refman/8.0/en/populating-spatial-columns.html

After you have created spatial columns, you can populate them with spatial data. Values should be stored in internal geometry format, but you can convert them to that format from either Well-Known Text (WKT) or Well-Known Binary (WKB) format. For ...

14.16.2 Argument Handling by Spatial Functions

https://dev.mysql.com/doc/refman/8.0/en/spatial-function-argument-handling.html

The Open Geospatial Consortium guidelines require that input polygons already be closed, so unclosed polygons are rejected as invalid rather than being closed. Spatial values, or geometries, have the properties described in Section 13.4.2.2, ...

14.16.9.1 Spatial Relation Functions That Use Object Shapes

13.4.1 Spatial Data Types

https://dev.mysql.com/doc/refman/8.0/en/spatial-type-overview.html

Some spatial data types hold single geometry values: GEOMETRY POINT LINESTRING POLYGON GEOMETRY can store geometry values of any type. The other single-value types (POINT, LINESTRING, and POLYGON) restrict their values to a particular geometry type.
