Leaflet is a free JavaScript - library , with the WebGIS - applications can be created. The library uses HTML5 , CSS3 and thus supports most desktop and mobile browsers. In addition to OpenLayers and Google Maps API , Leaflet is one of the most popular libraries and is used by websites such as GitHub , FourSquare , Pinterest and Flickr .
With Leaflet, Web Map Tile Services can easily be presented on a website together with your own geospatial data . The geodata can be loaded from GeoJSON files , for example , and provided with interactive functions such as pop-ups .
history
Vladimir Agafonkin developed Leaflet in 2010 at CloudMade under the name Web Maps API . The first version was published in 2011.
He has been working for Mapbox since 2013 , where he is responsible for the further development of Leaflet.
Functionalities
Leaflet supports Web Map Service (WMS), Web Map Tile Service (WMTS), GeoJSON , image overlays. Other types of levels or geodata formats can be integrated via plug-ins ( KML , CSV , WKT , GPX , ...).
Browser support
Leaflet supports Chrome , Firefox , Safari 5+, Opera 12+, Internet Explorer 7-11 and Microsoft Edge .
Comparison with other libraries
Compared to OpenLayers, Leaflet provides fewer features directly. Coordinate system conversions can only be carried out to a limited extent and Web Feature Services (WFS) are not supported. In return, Leaflet is much smaller in terms of lines of code (7,000 vs. 230,000; as of 2015) and the amount of data in the library (≈123 KB vs. ≈423 KB).
Libraries such as the Google Maps API or Bing Maps API outsource some functionalities such as geocoding and routing to servers and require an API key to be used.
