参数

参数	类型	描述
bbox	Array	extent 以 minX, minY, maxX, maxY 的顺序表示
cellSide	number	dimension of each cell
options	Object	可选参数：见下文

属性	类型	默认值	描述
units	string	kilometers	used in calculating cell size, can be degrees, radians, miles, or kilometers
properties	Object	{}	passed to each hexagon or triangle of the grid
mask	(Feature <(Polygon|MultiPolygon)>)		if passed a Polygon or MultiPolygon, the grid Points will be created only inside it
properties	Object	{}	passed to each point of the grid
