由于八十年代中期的第二代地球观测卫星(如陆地—5和 SPOT 卫星等)及遥感技术的发展已带有商品的色彩,这为欧洲及发展中国家探测其自然资源提供了更多的可能性。但在欧洲,今后要发展应用空间遥感技术有许多问题还待进一步考虑:第一,陆地卫星-5,SPOT 卫星以及现有的或计划于八十年代期间发射的第二代地球观测卫星,是否仍能满足欧洲九十年代
Since the development of the second generation of Earth observation satellites (such as land-5 and SPOT satellites) and the remote sensing technology in the mid-1980s has brought the color of the goods, this has provided more and more opportunities for European and developing countries to explore their natural resources possibility. However, in Europe, there are many issues to be solved in the application of space remote sensing technology in the future. Further consideration is needed. First, is Landsat-5, the SPOT satellite and the second generation of Earth observation satellites that are or are planned to be launched during the 1980s? Still able to meet the European nineties
