Delineation of Village House Structures, Amenities & other Land use Features using Digital Image Processing (DIP) of QuickBird Imagery of Chharora Village in Mewat District of Haryana (India)

6. Why QuickBird Imagery for Chharora Used?
As on date the QuickBird satellite, which was launched on 18 October 2001 by Boeing Delta II from Vandenberg Air Force Base, California, has the largest swath width as well as largest on-board storage, and provides highest resolution commercially available satellite imagery to the public. It has 61 cm resolution, which is even superior to IKONOS. Therefore, only QuickBird satellite data was chosen for the current exercise.

The Digital Globe provides to its customers a variety of options for accurate and timely availability of QuickBird satellite products which are mainly available in three type of file formats i.e. (i) Geo TIFF 1.0 (ii) NITF 2.0 and (iii) NITF 2.1. The QuickBird data is available at three levels of processing for delivery in a map projection. These are (i) geometrically raw imagery which is a basic imagery with the least amount of processing and required by those customers that desire to process the imagery themselves into a useable form, (ii) standard imagery with radiometric and geometric correction and delivered in a map projection, and (iii) Orthorectified imagery with radiometric, geometric, and topographic correction. Further, five product options are also available from Digital Globe in addition to these three processing levels. These are: (i) panchromatic products i.e. black & white products which enable superior visual analysis, (ii) products cover the visible and near-infrared wavelengths for multispectral analysis, (iii) black & white and multispectral products named as bundled products, (iv) colored products i.e. 3-band natural color or color infrared products that combine the visual information of three multispectral bands with the spatial information of the panchromatic band, and (v) Pan-sharpened i.e. 4-band products that combines the visual information of all four multispectral bands with the spatial information of the panchromatic band.

Thus QuickBird Satellite products are available to customers in industry standard image formats and media format in several processing and accuracy levels to suit customers’ needs either by tasking to collect fresh data or obtain from previously collected images. The QuickBird product may be obtained either from library or by tasking a fresh data order, for a scene based or area based polygon, which may contain a minimum of 4 vertices and a maximum of 1,000 vertices, consisting on the WGS84 ellipsoid the longitude/latitude (decimal degrees) geographic coordinates. The minimum and maximum size for an order polygon depends on the order type and the product selected

The metadata is also available with QuickBird imagery products that provides all the information required by the users to analyze and process the imagery as per given specifications. Similarly, a tile map file (.til) is available with every product to help place the tiles in product coordinates.

7..Findings:
Using digital image processing (DIP) on QuickBird imagery which covers Chharora village following thematic maps of Village Chharora, district Mewat in Haryana were prepared:

The first map indicate the location of the village and surroundings in a geo referenced Image which is given as map Map1..
