turf-hex-grid

turf.hex-grid(bbox, cellWidth, units, triangles)

Takes a bounding box and a cell size in degrees and returns a FeatureCollection of flat-topped hexagons (Polygon features) aligned in an "odd-q" vertical grid as described in Hexagonal Grids.

Parameters

parameter	type	description
bbox	Array.<number>	bounding box in [minX, minY, maxX, maxY] order
cellWidth	Number	width of cell in specified units
units	String	used in calculating cellWidth ('miles' or 'kilometers')
triangles	Boolean	generate hexgrid triangles instead of hexagons

Example

var bbox = [-96,31,-84,40];
var cellWidth = 50;
var units = 'miles';

var hexgrid = turf.hexGrid(bbox, cellWidth, units);

//=hexgrid

Returns FeatureCollection.<Polygon>, a hexagonal grid
