# @turf/point-grid ## pointGrid Creates a grid of points ### Parameters * `bbox` **[BBox][1]** extent of grid in \[minX, minY, maxX, maxY] order * `cellSide` **[number][2]** the distance between points * `options` **[Object][3]** Optional parameters (optional, default `{}`) * `options.units` **Units** the units of the cellSide value. Supports all valid Turf [Units][4] (optional, default `'kilometers'`) * `options.mask` **[Feature][5]<([Polygon][6] | [MultiPolygon][7])>?** if passed a Polygon or MultiPolygon, the grid Points will be created only inside it * `options.properties` **[Object][3]** passed to each point of the grid (optional, default `{}`) ### Examples ```javascript 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][8]<[Point][9]>** grid of points [1]: https://tools.ietf.org/html/rfc7946#section-5 [2]: https://developer.mozilla.org/docs/Web/JavaScript/Reference/Global_Objects/Number [3]: https://developer.mozilla.org/docs/Web/JavaScript/Reference/Global_Objects/Object [4]: https://github.com/Turfjs/turf/blob/master/packages/turf-helpers/README_UNITS.md [5]: https://tools.ietf.org/html/rfc7946#section-3.2 [6]: https://tools.ietf.org/html/rfc7946#section-3.1.6 [7]: https://tools.ietf.org/html/rfc7946#section-3.1.7 [8]: https://tools.ietf.org/html/rfc7946#section-3.3 [9]: https://tools.ietf.org/html/rfc7946#section-3.1.2 --- This module is part of the [Turfjs project](https://turfjs.org/), an open source module collection dedicated to geographic algorithms.
