hexGrid

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

• bbox Array<number> bounding box in [minX, minY, maxX, maxY] order
• cellSize number dimension of cell in specified units
• units string used in calculating cellWidth ('miles' or 'kilometers')
• triangles boolean whether to return as triangles instead of hexagons

Examples

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
