hexGrid

Takes a bounding box and the diameter of the cell and returns a FeatureCollection of flat-topped hexagons or triangles ( Polygon features) aligned in an "odd-q" vertical grid as described in Hexagonal Grids.
获取边界框和单元格的直径，并返回以“奇数-q”垂直网格排列的平顶六边形或三角形(features)的FeatureCollection(在六边形网格中描述)。

参数

参数	类型	描述
bbox	BBox	extent in minX, minY, maxX, maxY order
cellSide	number	length of the side of the the hexagons or triangles, in units. It will also coincide with the radius of the circumcircle of the hexagons.
options	Object	Optional parameters: see below

options选项

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
triangles	boolean	false	whether to return as triangles instead of hexagons

返回

FeatureCollection <Polygon> - a hexagonal grid

示例

var bbox = [-96,31,-84,40];
var cellSide = 50;
var options = {units: 'miles'};

var hexgrid = turf.hexGrid(bbox, cellSide, options);
