Multi-Temporal and MultiResolution Satellite data for Urban Land Use study through Change detection techniques

This paper has focused on the monitoring of land use land cover over 34 years. The study has based on secondary and satellite data along with statistical techniques as well as limited field verification. Jaipur City is situated in the North West zone of India. Its population has grown from 0.3 million in 1951 to 2.3 million in 2001 and 2.9 million in 2009. The annual average growth rate from 1971 to 2001 has been in the range of 4.1 to 4.7. The growth rate was the highest in the year 1981 but declined sharply by 0.6 per cent in 1991 and in grew again by 0.2 per cent in 2001. The impact of such growth is seen in the change in land use and led to the congestion of walled city. The population growth has major driving forces of land use change. The crop land has shrinked to 1.60 sq km/year, fallow land 2.94 sq km/ year, wasteland 0.59 sq km/year during 1975�2009, whereas the builtup l and has increased in the rate of 4.46 sq.km/ year or 1.02 per cent/year. Based on the use of multi resolution and multi temporal satellite data of 1975 to 2009, the spatial and temporal changes in the various types of land uses of city are detected and discusses. Urbanization is now a common feature of all third world countries. Primate cities and mega cities are emerging in developing countries. The growth in the population of cities in developing countries has been attributed to various factors which could be summarized in two: natural population increase and ruralurban mi gration. The cities of the third world have especially experienced population growth. Urban growth has been criticized for its inefficient use of land resources and energy and largescale en croachment on agricultural land. These impacts threaten the principle of sustainable development. However, sustainable urban growth management and development planning need to take account of the dynamic process of temporal urban change. The measurement of urban form can provide a more systematic analysis of the relationships between urban form and process (Yeh and Li, 2001). Batty and Longley (1994), classified urban growth as generally organic (or natural) or planned (or artificial) growth. The distinction between the two is multifold and often blurred. Basically, planned growth appears to be more manmade, in that the patterns produced are more regular, reflecting more control over the building process. Most cities and towns provide a blend of both, usually containing elements of the planned against a backcloth of organic growth. Urban growth is a broad and vague concept that can be subdivided into various types such as sprawling or compact, dispersed (scattered) or clustered, continuous or leapfrog, spontaneous or selforganizing, planned or organic. It may comp rise physical growth, population growth, economic growth and environmental change (decline), although there is often a focus on the physical aspect in the domains of remote sensing and GIS.
