Nair 2, Abstract The term change detection means visual change in the surface of the objects like water body, vegetation cover, settlements etc. first noticing the change in the object’s properties and notice after some years, observe the some change in object properties like shape, geographical location, function and chemical change. Everybody has a change in self-properties due to increase and decrease time to time. This change is called change detection. It denotes not only detection proper, but also identification and localization. Barkhal Lake is reducing continuously yearly. The present investigation shows that change detection of Barkhal Lake from 1973 – 1974 to 2008 using different time period satellite data like Toposheets, Cartosat-I & IRS -LISS-III data and mapping on 1:7,500 scales, using ArcGIS 9.3 & ERDAS Imaging 9.1 software. The Methodology used for mapping consists of preparation of base map, interpretation of satellite data, development of legend, ground truth collection, classification and finalization of maps in light of field information. The result developed from last about four decades. The Barkhal Lake completed dry in 2008. The present study successfully completed through capability of satellite remote sensing technology. Keywords: Barkhal Lake, Change Detection, Mapping 1. Background In order to find the periodic changes in the area of Barkhal Lake, satellite images of land Sat of October, 1999 and IRS P6 of October, 2005, based on the availability, were used. The methodology mentioned earlier resulted in the figure alongside. Since false color composites were placed in the imageries for visual interpretation, black color denotes the lake and water, while the increasing extent of electric blue characterize the spreading built up area of Faridabad. The predominantly red color denotes rocky outcrop with vegetation cover. From 1977 to 2006 almost 80 percent of the lake is gone The area of Lake Damdamma was about 3,37500 sq. meter in 1977 which stands at 87,000 sq. meter in 2006, while the Barkhal in 1977 covered about 2,33,600 sq. meter and was only 64,000 sq. meter in 2006. It is not only about area occupied, but also the depth of water. The Damdamma Lake is currently deepest in small pockets, which is about 2 odd meters, but in most areas it is not more than 0.15 meter. It now resembles a marshy tract rather than a lake. The Barkhal on the other hand is shallower at about 1 meter at certain deeper locations. The water held in the two lakes has dropped by 80 percent in the last 20 to 25 years and at this rate the remaining 20 percent will disappear in another 2 to 5 years. (Sulagna Chattopadhyay and Dr. Debapriya Dutta, Nov. Dec., 2007) The present investigation has carried out the change detection of Barkhal Lake with the following objectives:-  Mapping of the Change detection of Barkhal Lake.  Land use / land cover mapping of Faridabad district. 2. Materials and Methods 2.1 Study Area Study area is the Barkhal Lake which is located in northwestern side in Faridabad district of Haryana, lake is surrounded by rocky and undulating surface. The Aravalli range reached here through Mewat and Gurgaon districts. This area is important through stone mining. This area has not any perennial channel to water recharge to the Lake. The study area lies between 27° 51’ 15” N and 28° 30’ 52’’ N latitude and 77° 04’ 39’’ E and 77° 32’ 50’’ E longitude. 2.2 Technologies Used in the Research GIS and remote sensing technique is basically used for the present study to identify the various categories like ERDAS Imaging 9.1 (Used for Digital Image Processing), Arc GIS 9.3 (Visual Interpretation, Digitization and compose the Map), GARMIN GPS-72 Model for ground truth information and Google Chrome and Internet Explorer 9.1 for Web Browser.
