一、Introduction for Remote Sensing Application in Water Conservancy
The water problem of China is the most outstanding and complicated in the world. There are not enough water conservancy to the distribution of population, energy, mineral resources. Along with the national advancement of urbanization, industrialization, ecological civilization process, the implementation of the national development strategy and the effects of climate change, China's water security of the old and new problems are intertwined, old problems remain and new problems becomes increasingly prominent, those also give China’s water governance with the new connotation, put forward the new subject.
The combination of remote sensing and water conservancy has existed for 30 years, especially under the background of water conservancy informatization, the application of remote sensing technology to the water conservancy industry has been developed rapidly and has achieved great results. According to the development plan of the national water conservancy informatization, the application of new technologies and methods such as remote sensing is vigorously promoted while the construction of routine information acquisition facilities is improved. With the water conservancy application of GF remote sensing data in the key technology breakthrough, product development and demonstration application, the GF remote sensing data has been applied comprehensively in the field of water resources. By the implementation of water conservancy GF special projects marks GF satellite data a large-scale application in hydrology and water resources monitoring, floodflood and drought monitoring, soil and water conservation monitoring, water conservancy engineering and law-enforcement surveillance.
