• options Object Optional parameters (optional, default {})

  • 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
