@turf/rectangle-grid

rectangleGrid

Creates a grid of rectangular polygons with width and height consistent in degrees

Parameters

• bbox BBox extent of grid in [minX, minY, maxX, maxY] order. If the grid does not fill the bbox perfectly, it is centered.

• cellWidth number width of each cell, in units

• cellHeight number height of each cell, in units

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

  • options.units Units the units of the cell width and height value. Supports all valid Turf Units. If you are looking for rectangles with equal width and height in linear units (e.g. kilometers) this is not the module for you. The cellWidth and cellHeight is converted from units provided to degrees internally, so the width and height of resulting polygons will be consistent only in degrees. (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 bbox = [-95, 30 ,-85, 40];
var cellWidth = 50;
var cellHeight = 20;
var options = {units: 'miles'};

var rectangleGrid = turf.rectangleGrid(bbox, cellWidth, cellHeight, options);

//addToMap
var addToMap = [rectangleGrid]

Returns FeatureCollection<Polygon> a grid of polygons

This module is part of the Turfjs project, an open source module collection dedicated to geographic algorithms. It is maintained in the Turfjs/turf repository, where you can create PRs and issues.
