turf triangle-grid module

Usage no npm install needed!

<script type="module">
  import turfTriangleGrid from 'https://cdn.skypack.dev/@turf/triangle-grid';




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


  • 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 {})


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

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

var addToMap = [triangleGrid];

Returns FeatureCollection<Polygon> grid of polygons
