Leaflet is a widely used open source JavaScript library used to build web mapping applications. First released in 2011, it supports most mobile and desktop platforms, supporting HTML5 and CSS3. Along with OpenLayers, and the Google Maps API, it is one of the most popular JavaScript mapping libraries and is used by major web sites such as FourSquare, Pinterest and Flickr. Leaflet allows developers without a GIS background to very easily display tiled web maps hosted on a public server, with optional tiled overlays. It can load feature data from GeoJSON files, style it and create interactive layers, such as markers with popups when clicked. It is developed by Vladimir Agafonkin, who joined MapBox in 2013. == Use == A typical use of Leaflet involves binding a Leaflet "map" element to an HTML element such as a div. Layers and markers are then added to the map element. // create a map in the "map" div, set the view to a given place and zoom var map = L.map('map').setView((-0.09 ), 13); // add an OpenStreetMap tile layer L.tileLayer('http://.tile.osm.org///.png', ).addTo(map); The Leaflet library itself is accessible through the variable L.抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Leaflet (software)」の詳細全文を読む スポンサード リンク
