# geojson-polygons-equal
> Checks two GeoJSON Polygons or MultiPolygons for equality.
This includes detecting polygons whose coordinates are rotated left or right
differently.
## Usage
```js
var polyEqual = require('geojson-polygons-equal')
var poly1 = {
type: 'Polygon',
coordinates: [
[
[0, 0],
[0, 1],
[1, 1],
[1, 0],
[0, 0]
]
]
}
var poly2 = {
type: 'Polygon',
coordinates: [
[
[1, 1],
[1, 0],
[0, 0],
[0, 1],
[1, 1]
]
]
}
console.log(polyEqual(poly1, poly2))
```
outputs
```
true
```
## API
```js
var polyEquals = require('geojson-polygons-equal')
```
### polyEquals(poly1, poly2)
Compares the two GeoJSON objects `poly1` and `poly2`, which can be either
`Polygon` or `MultiPolygon` objects.
## Install
With [npm](https://npmjs.org/) installed, run
