National Remote Sensing Day Quiz 2021

Remote Sensing means acquisition of information about an object or phenomenon without making physical/direct contact with the object and thus in contrast to on-site observation, especially the Earth. Every 12th of August is celebrated as ‘National Remote Sensing Day’ in India, to celebrate the legacy of the great visionary, Dr. Vikram Sarabhai, who is popularly known as the Father of the Indian Space Program.
