The delineation of all buildings, paths/roads and other land use features within the Lal Dora of a village for which the planners usually rely on conventional methods of mapping is now possible with the advent of high resolution satellite data, like QuickBird imagery, which has worlds highest spatial resolution i.e. 61 cm at present. In the present study each and every house structure and village amenities such as schools, religious places, chaupals, telephone booths, hospital/dispensaries, NGOs office, and water supply sources like hand pumps, wells as well as water pipe line, irrespective of their conditions were delineated using the QuickBird imagery for village Chharora in Mewat district of Haryana. These features were studied through digital image processing with adequate ground truths and results are first time documented in this paper.
It was found that now it is possible with the use of high resolution Satellite Imagery having spatial resolution of less than 1 meter to map each and every village house structure and other land use feature, which was otherwise not possible even with other Satellite Imageries having more than one meter spatial resolution.
Further, in conventional surveying methods it was not possible to arrange all information on a single platform. The high-resolution satellite imagery also enabled to arrange and store the attributes data linked with digital image on single platform. This facilitates the entire data to be in GIS domain and thus making it possible for overlaying, querying, retrieving and analyzing, etc any information of the area of interest.
The present paper is based on the original field data collected under a joint research project carried out by the NISTADS (CSIR), New Delhi and MDS, Chharora (Mewat), Haryana. The main content of the paper is described below:
2. Location of the Study Area:
The Chharora village in Mewat district of Haryana (India) is located between latitude 28Ί 9 36 to 28Ί 10 48 north and longitude 76Ί 57 00 to 76Ί 58 48 east. The location of the village may be traced in Survey of India (SOI) toposheet no. 53 D/16 on 1:50,000 scale and 53 D/16/NE on 1: 25, 000 scale.
