Urban Settlements and Landuse Mapping with the emphasis on Slims in Kanpur Metropolis, India using Aerial Remote Sensing Technique
Study Area
Kanpur Metropolis the industrial hub of the state of Uttar Pradesh with a population of 1:69 Million and an urban area of approx 400 sq.km.is the eighth largest city in India it is situated on the bank of the river ganga and sprawls between the latitudes of 26 N and longitudes 80°30'E (Fig 1).

Methodology
Panchromatic black & White photography of the city of Kanpur and its environs on a scale of 1:10,000 was under taken by National Remote sensing agency in April 1986 anda total of 450 aerial using the elements of Photo interpretation viz. tone texture size were interpreted location and association after the interpretation of aerial photographs and delivery of the land use classes the data was transferred on a base map of 1:10,000 scale prepared with the help pf topomaps and guide map of survey of India using Planvariograph.
The interpretation was thoroughly checked in the field and was updated by integrating the ground information which was collected by visiting the area twice once after the interpretation and subsequently before the finalist ion of map when the inventory of various land use was prepared to show the kind and amount of space used by different urban activity systems.
Results and Discussion
Based on visual interpretation of large scale aerial photographs the land use classification system was worked out after considering the existing ground conditions and the scope of interpretation of each category from aerial photographs on the scale includes the contextual details of their association functions and over all importance of different land use classes in the city fabric the existing structure of the city reflects the resultant land use distribution of different periods in the past and their spatial scales. presently the city caries the unplanned land use distribution inherited from the past co existing with planned developments
The land use map prepared from the large scale aerial photograph depicts 23 land maps classes include urban rurban rural and other terrain aspects in the classification generic structure of the city growth is clearly evident in terms of density distribution of land use classes related to built up areas.
The spatial distribution pf slums follows the main activity nodes of the city related to trade commerce and industries in fact the present study reveals and demonstrates the scope of studying different phases of development of slums and its evolutionary sequence .The structural consolidation of the built up area of slum pockets in the city has convincing relationship with their addictiveness to the total city fabric. This is evident through several cases of slums having evolved along with the well serviced built up area largely having permanent construction style.
