@turf/triangle-grid

triangleGrid

Takes a bounding box and a cell depth and returns a set of triangular polygons in a grid.

Parameters

• bbox Array<number> extent in [minX, minY, maxX, maxY] order
• cellSide number dimension of each cell
• options Object Optional parameters (optional, default {})
  • options.units string used in calculating cellSide, can be degrees, radians, miles, or kilometers (optional, default 'kilometers')
  • options.mask Feature<Polygon>? if passed a Polygon or MultiPolygon, the grid Points will be created only inside it
  • options.properties Object passed to each point of the grid (optional, default {})

Examples

var bbox = [-95, 30 ,-85, 40];
var cellSide = 50;
var options = {units: 'miles'};

var triangleGrid = turf.triangleGrid(bbox, cellSide, options);

//addToMap
var addToMap = [triangleGrid];

Returns FeatureCollection<Polygon> grid of polygons
