• cellSide number the distance between points, in units
• 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 | MultiPolygon)>? 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 extent = [-70.823364, -33.553984, -70.473175, -33.302986];
var cellSide = 3;
var options = {units: 'miles'};

var grid = turf.pointGrid(extent, cellSide, options);

//addToMap
var addToMap = [grid];

Returns FeatureCollection<Point> grid of points
