11 Salient Features Creation of Maps from Text Files Maps from State and District Census code or Name(Choropleth Maps) & XY Data (Point Map) Classification based on Equal Range, Unique values (color ramp or color parameters, Edit-Range and color values) Web browser as a Independent Dynamic GIS viewer from POSTGIS Non-Spatial to Spatial : Simplified

12 The version component of the URL should be replaced with a version of the format v + version number. The current version is v1. The current available format is json. Optional Parameters limit: start-end values for retrieving response {"results":[{"name":"hyderabad","dist":"unnao","state":"uttar PRADESH","Longitude":"80.5","Latitude":"26.82"},{"Name":"Hyderabad BO Post Office","Dist":"JUNAGADH","State":"GUJARAT","Longitude":"70.17","Latitude":"21.1"},{" Name":"Hyderabad GPO Post Office","Dist":"HYDERABAD","State":"TELANGANA","Longitude":"78.48","Latitude":"17.3 9"}], "Results Matched":5, "status":"success" }

14 OpenLayers makes it easy to put a dynamic map in any web page. It can display map tiles and markers loaded from any source. OpenLayers has been developed to further the use of geographic information of all kinds. It is completely free, Open Source JavaScript An API for building web map applications Pure client-side JavaScript AJAX Supports open standards Supports closed standards, too BSD licensed

15 <html> <head> <script src=" </head> <body> <div style="width:100%; height:100%" id="map"></div> <script defer="defer" type="text/javascript"> var map = new OpenLayers.Map('map'); var wms = new OpenLayers.Layer.WMS("OpenLayers WMS", " {layers: 'basic'}); map.addlayer(wms); map.zoomtomaxextent(); </script> </body> </html>

16 Adding layer as Overlay var overlay = new OpenLayers.Layer.WMS("Bhuvan LULC 250K", " ", {layers: ' vector:as_lulc50k_0506, transparent:true} ); map.addlayer(overlay) Adding Controls Layer Switcher map.addcontrol(new OpenLayers.Control.LayerSwitcher()) Panzoombar map.addcontrol(new OpenLayers.Control.PanZoomBar()); Attribution map.addcontrol(new OpenLayers.Control.Attribution()); Scale Line - map.addcontrol( new OpenLayers.Control.ScaleLine()) Overviewmap - map.addcontrol( new OpenLayers.Control.OverviewMap())

17 Bringing Bhuvan Map/Sat/Hybrid using Openlayers Load a KML and see the result in Popup Overlay WMS service Thematic Layer eg. LULC Zoom to a particular layer extent Swipe a WMS layer

23 Geoprocessing AOI Analysis (for Thematic Services) Amenity Search (for Municipal GIS) Selected AOI Output Statistics Searching nearby Amenity Get Direction Results displayed on map Proximity Analysis

24 Automated Chain for Clip & Ship facility (For LULC 20K download) Create Shape file (using Draw Tool) Thematic-data dissemination through FTP Add Shape file (under Tools -> Add Layer) Add KML file (under Tools -> Add Layer)

25 Geo-Processing Spatial Query Shell Analysis Bhuvan Thematic Services Wasteland query Distribution of Fly-catchers Spatial Query Allows user to query the wasteland layer based on theme class and Area Allows user to query the Flycatcher distribution layer based on name, sighted location and species

26 WMS Manager (under Bhuvan General Tools) Listing external WMS Layers Forest Fire Regimes (For Disaster Services & Forest State portals) Consuming WMS Services from WMS Manager Utility for populating the layers available through WMS Service providers and to overlay on the Bhuvan Satellite imagery & thematic data A fire regime is the pattern, frequency and intensity of fires in an area. Three metrics are calculated :Average fire density(afd), Length of fire period (LFP), Standard deviation of AFD (SAFD)
