在美国,几乎每个人都知道美国和其它国家在绕地球的轨道上有许多卫星,然而许多人不知道这些卫星资料的好处並充分利用它,更多人则不知道这些可利用的资料的品种以及在什么地方能获得它们。据美国国家环境卫星服务署(NESS)人员的最新分析,由于环境卫星的监视,一年为美国至少节约一亿七千二百万美元,也许还是这个总数的许多倍。这个数字及其潜在的效益是十分吸引人的。
Almost everyone in the United States knows that the United States and many other countries have many satellites orbiting Earth. However, many people do not know the advantages of these satellite data and make full use of it, and many do not know the variety of these available materials And where to get them. According to the latest analysis by NESS personnel, due to environmental satellite surveillance, the United States saved at least 172 million U.S. dollars a year, perhaps many times this total. This figure and its potential benefits are very attractive.
