公路勘测设计工作是公路建设的尖兵,实现公路建设的现代化必然包括实现公路勘测设计的现代化。根据我们国家的具体情况,要实现公路勘测设计的现代化是有条件的。首先,我国测绘部门在解放后进行了大量航空摄影测量工作。第一代的航空象片已完成,第二代航空象片正在有计划地摄制。这些,为我们提供了公路勘测设计现代化的基本条件。例如,根据已有航空象片,结合地形图,利用简单的观察工具——反光立体镜,就可以作简单的量测,基本上可满足公 Highway survey and design work is a pioneer in highway construction. To achieve the modernization of highway construction must include the modernization of highway survey and design. According to the specific conditions of our country, it is conditional to realize the modernization of highway survey and design. First, China’s surveying and mapping department conducted a large number of aerial photogrammetry after the liberation. The first generation of aerial photographs have been completed, the second generation of aerial photographs are being produced in a planned manner. These provide us with the basic conditions for the modernization of highway survey and design. For example, based on the existing aerial photographs, combined with topographic maps, using a simple observation tool - reflective stereoscope, you can make simple measurements, basically meet the public
