# random-points-generator [](https://www.npmjs.com/package/random-points-generator) [](https://www.npmjs.com/package/random-points-generator) [](https://github.com/tsamaya/random-points-generator/blob/master/LICENSE) [](https://github.com/prettier/prettier) Generates _n_ random points based on @turf/random. The value added regarding @turf/random is the filter. Indeed, here points can be generated inside a GeoJSON polygon. And it comes with : - a command line tool, - a node library, - a browser library [](https://circleci.com/gh/tsamaya/random-points-generator) [](https://codecov.io/gh/tsamaya/random-points-generator) [](https://codeclimate.com/github/tsamaya/random-points-generator/maintainability) [](https://www.meterian.io/report/gh/tsamaya/random-points-generator) [](https://app.fossa.com/projects/git%2Bgithub.com%2Ftsamaya%2Frandom-points-generator?ref=badge_shield) ## Prerequisites - node ## Node Usage ```sh $ npm i random-points-generator ``` or ```sh yarn add random-points-generator ``` or ```sh pnpm add random-points-generator ``` ## browser Usage ```html <script src="https://unpkg.com/random-points-generator"></script> <script> const fc = geotools.random(5); </script> ``` ## API #### function random (number, options) | Name | Description | Type | Default | | --------- | ---------------------------- | ------- | --------- | | `number` | number of points to generate | Integer | 10 | | `options` | random options | Object | undefined | returns a [FeatureCollection](https://tools.ietf.org/html/rfc7946#section-3.3) of [Points](https://datatracker.ietf.org/doc/html/rfc7946#section-3.1.2) > `options` | `Options` | Description | | ---------- | -------------------------------------------------------------------------------------------------------------------------------- | | `bbox` | Array<number> extent in [ minX, minY, maxX, maxY ] order which means (southwest lng, lat northeast lng,lat) | | `features` | GeoJSON polygons as features or a FeatureCollection | | `unkink` | `true\|false` [Default is true] Unkink Polygon ([see](https://turfjs.org/docs/api/unkinkPolygon)) before processing the features | ### Examples **ESM** ```javascript import RandomGenerator from 'random-points-generator'; console.log(JSON.stringify(RandomGenerator.random(5))); ``` will output something like : ```JSON {"type":"FeatureCollection","features":[{"type":"Feature","properties":{},"geometry":{"type":"Point","coordinates":[-57.67197760979268,42.78314165298585]}},{"type":"Feature","properties":{},"geometry":{"type":"Point","coordinates":[72.83765393077084,-59.52263527885765]}},{"type":"Feature","properties":{},"geometry":{"type":"Point","coordinates":[54.502068476617396,-60.928402442511306]}},{"type":"Feature","properties":{},"geometry":{"type":"Point","coordinates":[-22.331900675385647,39.51543790400138]}},{"type":"Feature","properties":{},"geometry":{"type":"Point","coordinates":[-149.45526699981158,-74.96319889821024]}}]} ``` **CJS** ```javascript const RandomGenerator = require('random-points-generator'); const points = RandomGenerator.random(3); console.log(JSON.stringify(points)); ``` will output something like : ```JSON {"type":"FeatureCollection","features":[{"type":"Feature","geometry":{"type":"Point","coordinates":[126.41316810428155,-47.548372609587574]},"properties":{}},{"type":"Feature","geometry":{"type":"Point","coordinates":[97.69989737806617,-47.200575920302434]},"properties":{}},{"type":"Feature","geometry":{"type":"Point","coordinates":[24.264802630637277,72.69680002654108]},"properties":{}}]} ``` ### From the command line - clone or fork the repo - `cd random-points-generator` - run `npm install` - run `./bin/random-points-generator --help` to get options ```bash Usage: bin/random-points-generator [options] Options: --help, -h Show help [boolean] --number, -n [default: 10] --verbose, -v [default: false] Examples: bin/random-points-generator Generates 10 random coordinates, output to console in GeoJSON format bin/random-points-generator -n 1000 Generates 1000 random coordinates --xmin=-2 --xmax=4 --ymin=-45 --ymax=50 with these bounding box bin/random-points-generator -i Generates 10 random coordinates world_countries.geojson within polygons from file world_countries.geojson ``` ## Converting to csv TODO ## Revision History | Version | Date | Description | | --------------- | ---------- | --------------------------------------- | | `v2.0.0` | 07/07/2025 | Release v2 | | `v2.0.0-beta.3` | 01/07/2025 | Export default | | `v2.0.0-beta.2` | 30/06/2025 | Improves doc and upgrade deps | | `v2.0.0-beta.1` | 23/06/2025 | Refactor using TypeScript and Vitest | | `v1.10.0` | 23/06/2025 | Upgrade deps packages | | `v1.9.1` | 03/11/2024 | deps: Eslint 9 and pnpm | | `v1.9.0` | 29/07/2024 | Upgrade deps packages | | `v1.8.0` | 26/01/2023 | Adds optional unkink polygons parameter | | `v1.7.6` | 31/03/2021 | Upgrade deps packages | | `v1.7.5` | 22/11/2020 | Upgrade deps packages | | `v1.7.4` | 09/12/2019 | Upgrade deps packages | | `v1.7.3` | 09/12/2019 | Upgrade deps packages | | `v1.7.2` | 16/08/2019 | Upgrade deps packages | | `v1.7.1` | 16/08/2019 | Build removes node 6 | | `v1.7.0` | 14/08/2019 | Build / test on node 10 | | `v1.6.1` | 10/12/2018 | Missing Built Files | | `v1.6.0` | 10/12/2018 | Upgrade deps packages | | `v1.5.2` | 01/05/2018 | fixes unnecessary verbose message | | `v1.5.0` | 25/03/2018 | add a browser package | | `v1.4.0` | 20/02/2018 | Use single turf modules | | `v1.3.0` | 07/11/2017 | Unkink input polygons | | `v1.2.0` | 21/05/2017 | Rewrite with es6 notation | | `v1.1.0` | 25/04/2017 | Split command line and lib | | `v1.0.0` | 03/10/2016 | Creation : a tool command line | ## Resources _resources_ folder contains Large Scale Data from [Natural Earth](http://www.naturalearthdata.com/) ## Licensing Licensed under the MIT License A copy of the license is available in the repository's [LICENSE](LICENSE) file.
