Bangalore, one of the Indian metropolitan cities, has witnessed rapid urbanization during the last decade with an overwhelming spatial growth of 696 sq. km to 2185 sq.km within a span of ten years (2006 to 2016). With this exponential rate of urban g

Broadly satellite images are available in two categories (1) high spectral resolution but less spatial resolution (2) high spatial resolution but less spectral resolution. But in certain applications, images with high spatial as well as high spectral

Carbon dioxide (CO2) is the key atmospheric gas that controls the earth's greenhouse effect, and forests play a major role in abating the atmospheric CO2 by storing carbon as biomass. Therefore, it is vital to understand the role of different forests

In this digital world, there is a large requirement of high resolution satellite image. Images at a low resolution may contain relevant information that has to be integrated with the high resolution image to obtain the required information. This is b
