Science reporter

Science reporter FOR the many comforts, ease of transport, economic opportunities, and other life style benefits, more and more people are choosing to migrate to cities. The UN estimates that more than 54% of the world's population, Science reporter that is over 3.8 billion people, live in urban areas in 2017. This number will grow rapidly in the future. With so many cities coming up, often government censuses, Science reporter which happen once a decade, are too slow to be able to track the growth and estimate the needs of such large, concentrated populations of people. Science reporter A solution to track uncontrolled urban growth or sprawl is to use satellite imagery. However, for tropical countries like India, science reportermagazine this is not a practical solution as optical satellite imaging is blocked by clouds that are persistent in the rainy seasons. Advanced radar satellites can be used, however, science reporter magazine it can be challenging to identify urban areas with these satellites. Dr. Shaunak De and Dr. Avik Bhattacharya at the Microwave Remote Sensing Lab, science reporter magazine Indian Institute of Technology Bombay have discovered a technique by which even challenging urban settlements can be correctly identified. science reporter magazine This was done by teaching an artificial intelligence algorithm the physics of radar scattering, much like you would teach a human expert!
