2006年2月18日,中国1:5万基础地理信息数据库工程通过了国家有关部门的验收。这是我国迄今历时最长、投入经费最多、工程量最大、技术最复杂、应用前景最广泛的基础地理数据库,在中国地理空间数字化建设进程中具有里程碑意义。由于1:5万比例尺地形图一直是军民合用的基本图,因此,基于1:5万地形图建立的基础地理信息数据库,不仅将在国民经济建设中发挥重要作用,而且在国家安全和军事活动中也是必不可少的。
On February 18, 2006, China’s 1: 50000 basic geographic information database project passed the acceptance of the relevant state departments. This is the most basic geographic database in our country which lasted the longest, the largest investment, the largest amount of engineering, the most complicated technology and the most extensive application prospect so far. It has a milestone in the process of digitizing geospatial development in China. As 1: 50000 scale topographic maps have always been the basic map of military and civilian cooperation, a database of basic geographic information based on 1: 50000 topographic maps will not only play an important role in the national economic construction, but also play an important role in national security and military activities In the middle is also essential.
