Leaflet Demo Tutorial

Demo Tutorial Part 1

Leaflet is an open-source JavaScript library for mobile-friendly interactive maps. This documentation will help you to create your first map with Leaflet and you will learn some basic mapping principles. Basic usage:

Lets begin with the most basic HTML page:


			  
<html>
  <head>
  </head>
     
  <body>
  </body>
</html>

Include these Leaflet CSS and JS files in head tag:


			  <link rel="stylesheet" href="http://cdn.leafletjs.com/leaflet-0.6.4/leaflet.css" />
<script src="http://cdn.leafletjs.com/leaflet-0.6.4/leaflet.js"></script>

Add the map div on the page where you want to display the map and set the height/width for this div


<div id="map" class="map" style="height: 500px; width: 500px;"></div>

Use the following minimal JavaScript code inside the <script> tag to initialize the Map.


			  var map = L.map('map', {
	center: [34,-88],
	zoom: 4
});
L.tileLayer('http://{s}.tile.openstreetmap.org/{z}/{x}/{y}.png').addTo(map);

Putting It All Together

<script src="http://cdn.leafletjs.com/leaflet-0.6.4/leaflet.js"></script>
</head>
<body>
<div id="map" class="map" style="height: 500px; width: 500px;"></div>
<script>
var map = L.map('map', {
	center: [34,-88],
	zoom: 4
});
L.tileLayer('http://{s}.tile.openstreetmap.org/{z}/{x}/{y}.png').addTo(map);
</script>
</body>
</html>

Demo Tutorial Part 2: Showing GeoServer Layer

We will now add a GeoServer layer to our base map. In this case the topp:states layer that comes with GeoServer.

To do so, simply add the lines below to our existing javascript block.

		  
			  
			   var wmsLayer= L.tileLayer.wms("http://localhost/geoserver/wms", {
        layers: 'topp:states',
        format: 'image/png',
        transparent: true
    });
    map.addLayer(wmsLayer);

The entire javascript block should new look like this:

	
			 <script> 
			  var map = L.map('map', {
	center: [34,-88],
	zoom: 4
});
L.tileLayer('http://{s}.tile.openstreetmap.org/{z}/{x}/{y}.png').addTo(map);


			  
			   var wmsLayer= L.tileLayer.wms("http://localhost/geoserver/wms", {
        layers: 'topp:states',
        format: 'image/png',
        transparent: true
    });
    map.addLayer(wmsLayer);
	</script>

Gives us:

				  
			  
			  <!DOCTYPE html>
<html>
<head>
<link rel="stylesheet" href="http://cdn.leafletjs.com/leaflet-0.6.4/leaflet.css" />
<script src="http://cdn.leafletjs.com/leaflet-0.6.4/leaflet.js"></script>
</head>
<body>
<div id="map" class="map" style="height: 500px; width: 500px;"></div>
<script> 
			  var map = L.map('map', {
	center: [34,-88],
	zoom: 4
});
L.tileLayer('http://{s}.tile.openstreetmap.org/{z}/{x}/{y}.png').addTo(map);


			  
			   var wmsLayer= L.tileLayer.wms("http://geo.acugis.com/geoserver/wms", {
        layers: 'topp:states',
        format: 'image/png',
        transparent: true
    });
    map.addLayer(wmsLayer);
	</script>
</body>
</html>

or this:

	
			  
			  <!DOCTYPE html>
<html>
<head>
<link rel="stylesheet" href="http://cdn.leafletjs.com/leaflet-0.6.4/leaflet.css" />
<script src="http://cdn.leafletjs.com/leaflet-0.6.4/leaflet.js"></script>
</head>
<body>
<div id="map" class="map" style="height: 500px; width: 500px;"></div>
<script> 
			  
    var map = L.map('map').setView([0, 0], 2);        
    var osmUrl='http://{s}.tile.openstreetmap.org/{z}/{x}/{y}.png';
  	var osmAttrib='Data © <a href="http://openstreetmap.org">OpenStreetMap</a> contributors';
  	var osm = new L.TileLayer(osmUrl, {minZoom: 2, maxZoom: 8, attribution: osmAttrib});
    map.addLayer(osm);
	//change localhost below to your IP or hostname
    var wmsLayer= L.tileLayer.wms("http://localhost/geoserver/wms", {
        layers: 'topp:states',
        format: 'image/png',
        transparent: true
    });
    map.addLayer(wmsLayer);
