Example

smaple input polygon

In order to gain grid polygons your polygon must be in a closed line-ring format like:

let polygon = {
  type: 'Polygon',
  coordinates: [
    [

Usage

const { createGrids } = require('grids-over-polygon');

const {createGrids} = require('grids-over-polygon');

const yourPolygon = [...];
const yourSizeInKilometers = 0.1; // for grid size in square kilometers/meters

let output = createGrids(yourPolygon, yourSizeInKilometers);
