当代高技术的发展以无可辩驳的事实证明:信息技术是商品经济发展中最活跃的生产力。利用信息技术提高工作效率、预测决策水平,促进管理和决策的科学化、民主化,在我国具有重要意义。遥感技术和地理信息系统做为信息技术的重要组成部分,在“六五”期间已引起了各部门的重视和深入研究,为我国四化建设做出了重要贡献。但是,必须看到我国遥感技木和GIS发展的现状还远不能适应当代科技发展和经济建设的需要。尽管国家对遥感技术和地理信息系统投资较多,软、硬件也有一定的储备,培养了相当数量的人才,而遥感 The development of modern high technology has irrefutable facts that information technology is the most active productive force in the development of commodity economy. The use of information technology to improve work efficiency, predict the level of decision-making, and promote scientific and democratic management and decision-making are of great significance in our country. As an important part of information technology, remote sensing technology and geographic information system have drawn the attention of all departments and conducted in-depth studies during the period of the Sixth Five-Year Plan, making an important contribution to the four modernizations of our country. However, we must see that the status quo of remote sensing technology and GIS development in our country is far from being able to meet the needs of the development of science and technology and economic construction. Although the state invests more in remote sensing technology and geographic information system, there are some reserves of software and hardware, and a considerable number of talents have been cultivated.
