Urban Sprawl Analysis using Remote Sensing New Delhi, India Ann Jyothis Raj and Alicia L. Simonti Professor Yelena Ogneva-Himmelberger Change Detection Results and Discussion The study illustrates that the areas of change in terms of urban sprawl are predominately due to loss of both vegetation and barren land. Additionally, the original urban areas have become more dense and spreads outwards into the suburbs. India occupies only two per cent of the world’s total landmass. Yet it is home to 15 per cent of the world’s total population. Urban growth is characteristic of most Indian cities, with that of Delhi being especially dramatic, as the satellite images from 1977 and 1999 clearly show.

The purple areas in this image represent change, whereas the beige represents no change o o Abstract In 1975, Delhi had a population of 4.4 million people or 3.3 percent of India’s entire urban population. In 2000, the city had 12.4 million inhabitants. By 2015, Delhi’s population is expected to be 20.9 million, this has tremendous implications on urban sprawl. This study examines the extent of urban sprawl in and around the Union Territory of Delhi over two decades, using remotely sensed images of 1977 and 1999.
