Use Night Time Light Remote Sensing to Discover Dragon Fruit Plantations in Vietnam

The nighttime light (NTL) on the surface of earth is a great symbol indicating the changes made by human activities such as urban lighting, gas flaring and other living or producing activities. Therefore NTL remote sensing can be used for discovering and monitoring the human activities connecting NTLs. In this paper, NTL remote sensing has been successfully used in agricultural area, based on the light supply system of dragon fruit plantations. A method of extracting dragon fruit plantations had been proposed, and exemplified in Binh Thuan province of Vietnam.
