The main evolution of remote sensing for land resources of China in recent years

The development of earth observation techniques has expanded and deepened the application area of remote sensing further. Meanwhile, the application on remote sensing for land resources has entered a new era marked by high spatial resolution, high spectral resolution and high temporal resolution. Nowadays, remote sensing techniques serve as an important support for the great discovery of geosciences and the modernization of geological work. The remote sensing satellites of our country develop to groups, networks and seriations; its application area develops to fine and quantitative direction; the recent researches both in basic field and application area develop to integration. In the following years, the need for remote sensing application will be more and more imminent. It is an inevitable tide for land remote sensing to use all-weather and multi-angle observation system by which we can observe the earth real-time to survey, suspect and research the resources, energy, and environment What is more, impractical hyper-spectral remote sensing system is an urgent technical platform problem to be solved for further application in remote sensing for resources and energy.
