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

摘要

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 built-up land 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.
