欧洲空间局正在研究欧洲在观测地球方面的潜在力量,其成员国认为首先要致力于地球大陆的观测,从而监测并及时了解各种大面积土地(包括农村和城市)的利用情况,监测各种作物的生产,估计其产量潜力,监测并管理有关森林的采伐和换代的规划,以及协助预报并控制雨水和雪水的流量,使潜在洪灾趋于最低限度,而使雨水和雪水的利用达到最大限度.欧洲空间局早期进行的为达到上述目标的有关卫星系统的研究已成为进一步深入开展这方面活动的背景,预计在1991年～1992年发射的大地观测卫星,除解放欧洲本身的需要之外,也可用于满足发展中国家的需要.
The European Space Agency is studying the potential of Europe in observing the Earth and its member states believe that the first priority is to observe Earth’s continents to monitor and keep abreast of the availability of large areas of land, including rural and urban areas, Crop production, estimating its yield potential, monitoring and managing planning for harvesting and replacement of forests, and helping to forecast and control the flow of rain and snow water, minimizing potential flooding and achieving rainwater and snow water use To the maximum, the early studies conducted by the European Space Agency on satellite systems to achieve the above objectives have become a backdrop to furthering this activity. It is anticipated that the Earth observation satellites launched between 1991 and 1992, in addition to the needs of liberating Europe itself In addition, it can also be used to meet the needs of developing countries.
