How to use WMS services

Bhuvan Web Map Services

Bhuvan services are OGC compliant such as WMS (Web Map Service) and WMTS (Web Map Tile Service) towards Interoperability. All Bhuvan's Geospatial services can be consumed as OGC services either as WMS or WMTS and plotted on any compatible clients/Web browsers (eg.QGIS,Gaia,OpenLayers).Thematic Maps of 1:50000, 1:250000 – Land Use Land Cover (LULC), Wasteland, Geomorphology, Lineament, Urban Land Use and Land Cover, Erosion, Water Bodies, Salt Affected & Water Logged Area, Flood Hazard, Flood Annual Layers, Glacial Lakes and Waterbodies(Indian Himalayan region) can be consumed as WMS/WMTS web service

Consuming Bhuvan Web Services in Web Applications

By Using Open Source 'Open Layers' JavaScript Library,Bhuvan OGC WMS/WMTS services can be consumed in your web applications. Steps to consume bhuvan services are

Step 1 Download JavaScript Library from http://Openlayers.org and place in web server root directory. (In Case of Apache place in htdocs folder,IISC in www folder)

Step 2 Navigate to the examples folder and take any one as base and do the changes or create new html page as follows

Step 3 Reference the API library from OpenLayers .

<script src="../lib/OpenLayers.js"></script>

Additionally, if you wish to use OpenLayers in a web application, you can include

http://www.openlayers.org/api/OpenLayers.js in your page, to always get the latest release.

Step 4 In order to create the viewer, you must first create a map. The OpenLayers.Map constructor requires one argument: This argument must either be an HTML Element, or the ID of an HTML element. This is the element in which the map will be placed.

var map = new OpenLayers.Map('map');

Step 5 The next step to creating a viewer is to add a layer to the Map. OpenLayers supports many different data sources like WMS/WFS/TMS/WMTS to WorldWind. In this example, you are accessing WMS from Bhuvan. You can visit Bhuvan Thematic Services portal and can find the layer name, url details

Var wms =new OpenLayers.Layer.WMS("Bhuvan LULC 50K",

"https://bhuvan-vec2.nrsc.gov.in/bhuvan/wms",

{layers: 'lulc:BR_LULC50K_1112'} );

map.addLayer(wms);

Step 6 Finally, in order to display the map, you must set a center and zoom level. In order to zoom to fit the map into the window, you can use the zoomToMaxExtent function, which will zoom as close as possible while still fitting the full extents within the window.

map.zoomToMaxExtent();
