Abstract
The cities in any developing countries are the main backbone for the economic growth of the country. In recent days, developing countries faces major issues such as increases in urbanisation and population. An assessment of built-up area plays an important role during the regional planning and infrastructure development of the city. Mysuru has a unique place in the world due to its culture, green cover, and pleasant weather. The present study assess the decade changes in a built-up area of Mysuru District, Karnataka State, India using multispectral remotely sensed data of 2009 and 2019. Change detection of an entire Mysuru District has been carried out with respect to the built-up area of cities and taluks. An experimental result shows that 4.66% of built-up cover in 2009 was increased to 6.56% in 2019. These results show that the built-up cover of the Mysuru district increased by 1.9% over the decade. Overall classification was estimated to be 88.7% for 2009 and 85.4% for 2019.
