把地球搬回家我理解,我们的测绘就是把地球搬回家。我说的是把地球表面的东西搬回家。我们人类活动都在地球表面进行,要对地面进行勘测,施行一些工程之后还要进行一些管理,所以一定要对地表面进行测绘。很多部门都要用测绘成果,比如水利部门、铁路部门、军事等等各个部门都要用到。 Moving the Earth home I understand that our mapping is moving the Earth home. What I’m talking about is moving something on the surface of the earth home. All of our human activities are conducted on the surface of the earth. After conducting surveys on the ground and carrying out some projects, we must conduct some management. Therefore, we must map the surface of the earth. Many departments should use surveying and mapping results, such as water conservancy departments, railway departments, military departments and so on.
