“遥感”,是一门新兴的学科。近10多年来,随着空间科学,光电技术及计算机技术的迅速发展,遥感技术应用,越来越广泛,越来越深入,已成为人们认识世界、改造世界的有力武器。我国幅员辽阔,资源丰富。由于自然地理条件复杂,有些资源尚未查清。为了满足国民经济建设的需要,我国成功地发射了用于国土资源调查的科学实验卫星。卫星获取的图像,质地清晰、信息丰富,为我国航天遥感在经济建 “Remote Sensing” is a new discipline. In the recent 10 years, with the rapid development of space science, optoelectronic technology and computer technology, the application of remote sensing technology has become more and more extensive and deepening. It has become a powerful weapon for people to know the world and transform the world. My country is vast and rich in resources. Due to the complexity of natural and geographical conditions, some resources have not yet been identified. In order to meet the needs of national economic construction, our country has successfully launched the scientific experimental satellite for land and resources investigation. Satellite images, clear texture, rich information, as China’s space remote sensing in the economy
