	Constructors	构造器
	:command:`ST_MakePoint(Longitude, Latitude)`	:command:`ST_MakePoint(Longitude, Latitude)`
	Returns a new point. Note the order of the coordinates (longitude then latitude).	返回一个新的点。注意坐标分量的顺序（先经度，然后纬度）。
	:command:`ST_GeomFromText(WellKnownText, srid)`	:command:`ST_GeomFromText(WellKnownText, srid)`
	Returns a new geometry from a standard WKT string and srid.	输入 WKT 字符串和 srid 并返回一个新的几何对象。
	:command:`ST_SetSRID(geometry, srid)`	:command:`ST_SetSRID(geometry, srid)`
	Updates the srid on a geometry. Returns the same geometry. This does not alter the coordinates of the geometry, it just updates the srid. This function is useful for conditioning geometries created without an srid.	更新几何图形的空间参考标识符(SRID)。该函数返回原几何图形（坐标值不变），仅更新其SRID值，适用于处理未定义空间参考的几何数据。
	:command:`ST_Expand(geometry, Radius)`	:command:`ST_Expand(geometry, Radius)`
	Returns a new geometry that is an expanded bounding box of the input geometry. This function is useful for creating envelopes for use in indexed searches.	返回一个基于输入几何图形扩展后的边界框新几何图形。该函数适用于为索引搜索创建包络范围。
	Outputs	输出
	:command:`ST_AsText(geometry)`	:command:`ST_AsText(geometry)`
	Returns a geometry in a human-readable text format.	返回几何图形的可读文本格式。
	:command:`ST_AsGML(geometry)`	:command:`ST_AsGML(geometry)`
	Returns a geometry in standard OGC :term:`GML` format.	返回符合OGC标准 :term:`GML`格式的几何图形表示。
	:command:`ST_AsGeoJSON(geometry)`	:command:`ST_AsGeoJSON(geometry)`
	Returns a geometry to a standard `GeoJSON <http://geojson.org>`_ format.	将一个几何对象转为标准的 `GeoJSON <http://geojson.org>`_ 格式。
	Measurements	量测
	:command:`ST_Area(geometry)`	:command:`ST_Area(geometry)`
	Returns the area of the geometry in the units of the spatial reference system.	返回基于坐标系单位的几何对象的面积。
