Remote Sensing of Lakes and Marshes Using Helicopter Based System

The research aimed to develop a non-contact sensing system using an unmanned helicopter mounted with some sensors to specify an effective wavelength band for the eutrophication of lakes and marshes. Also, it aims to make an estimation model of each element. The reason why an estimation model is needed is because a number of lakes and marshes are lost due to some problems like decrease in water quality, eutrophication, ecological correctness, and deterioration of waterfront environment. These are posed by human activity such as landfill and reclamation in improvement project of farmland and housing land in the recent years. Lakes and marshes form a complex ecosystem cycle, receive effects in physics, chemistry, and living things and have multi-functionality. In order to estimate model, a multi spectral image sensor, a photon sensor, and a highly accurate spectroradiometer were used as sensing system. The end goal was to understand the characteristic of lakes and marshes, and how to manage them properly.
