Leaflet-providers
=================
An extension to [Leaflet](http://leafletjs.com/) that contains configurations for various free[1](#what-is-free) tile providers.
# Installation
Download [leaflet-providers.js](https://raw.githubusercontent.com/leaflet-extras/leaflet-providers/master/leaflet-providers.js) and include it in your page after including Leaflet, e.g.:
...
# Usage
Leaflet-providers [providers](#providers) are refered to with a `provider[.]`-string. Let's say you want to add the nice [Watercolor](http://maps.stamen.com/#watercolor/) style from Stamen to your map, you pass `Stamen.Watercolor` to the `L.tileLayer.provider`-constructor, which will return a [L.TileLayer](http://leafletjs.com/reference.html#tilelayer) instance for Stamens Watercolor tile layer.
```Javascript
// add Stamen Watercolor to map.
L.tileLayer.provider('Stamen.Watercolor').addTo(map);
```
# Providers
Leaflet-providers provides tile layers from different providers, including *OpenStreetMap*, *Stamen*, *Esri* and *OpenWeatherMap*. The full listing of free to use layers can be [previewed](http://leaflet-extras.github.io/leaflet-providers/preview/index.html). The page will show you the name to use with `leaflet-providers.js` and the code to use it without dependencies.
## Providers requiring registration
In addition to the providers you are free1 to use, we support some layers which require registration.
### HERE (formerly Nokia).
In order to use HERE layers, you must [register](http://developer.here.com/). Once registered, you can create an `app_id` and `app_code` which you have to pass to `L.tileLayer.provider` in the options:
```Javascript
L.tileLayer.provider('HERE.terrainDay', {
app_id: '',
app_code: ''
}).addTo(map);
```
[Available HERE layers](http://leaflet-extras.github.io/leaflet-providers/preview/#filter=HERE)
### Mapbox
In order to use Mapbox maps, you must [register](https://tiles.mapbox.com/signup). You can get map_ID (i.e mapbox.satellite) and ACCESS_TOKEN from [Mapbox projects](https://www.mapbox.com/projects):
```JavaScript
L.tileLayer.provider('MapBox', {
id: 'ID': '',
accessToken: ''
}).addTo(map);
```
### Thunderforest
In order to use Thunderforest maps, you must [register](https://thunderforest.com/pricing/). Once registered, you have an `api_key` which you have to pass to `L.tileLayer.provider` in the options:
```JavaScript
L.tileLayer.provider('Thunderforest.Landscape', {apikey: ''}).addTo(map);
```
### Esri/ArcGIS
In order to use ArcGIS maps, you must [register](https://developers.arcgis.com/en/sign-up/) and abide by the [terms of service](https://developers.arcgis.com/en/terms/). No special syntax is required.
[Available Esri layers](http://leaflet-extras.github.io/leaflet-providers/preview/#filter=Esri)
### Geoportail France
In order to use Geoportail France resources, you need to obtain an [api key]( http://professionnels.ign.fr/ign/contrats/) that allows you to access the [resources](https://geoservices.ign.fr/documentation/donnees-ressources-wmts.html#ressources-servies-en-wmts-en-projection-web-mercator) you need. Pass this api key and the ID of the resource to display to `L.tileLayer.provider` in the options:
```JavaScript
L.tileLayer.provider('GeoportailFrance', {
variant: '',
apikey: ''
}).addTo(map);
```
Please note that a public api key (`choisirgeoportail`) is used by default and comes with no guarantee.
4 aliases are also provided for common Geoportail resources : `GeoportailFrance`, `GeoportailFrance.orthos`, `GeoportailFrance.ignMaps` and `GeoportailFrance.parcels` (See index.html demo).

### What do we mean by *free*?
1
We try to maintain leaflet-providers in such a way that you'll be able to use the layers we include without paying money.
This doesn't mean no limits apply, you should always check before using these layers for anything serious.
