村镇规划在实施过程中,由于受到历史上形成村镇的诸多制约条件,影响了规划的顺利实施。为快速优质地完成村镇规划,今推荐一种简便易学、快速准确的测绘方法——用直角坐标系控制村镇规划的实施方法。 它的原理是:从规划控制基线上测一个直角为规划的纵轴(纵坐标),以规划控制基线为一个横轴(横坐标),从而形成一个直角坐标系。用直角坐标系的原理,依次测量推算出所需要的各种数据。这种方法有数据准确、速度快、实施简便.易学等优点。 现举例说明:(如图) 规划前的老街道与坐标纵轴形成一个夹角,这个夹角可用经纬仪测得,设为α,老街的长度,可用钢 In the implementation process of village and township planning, due to the constraints imposed on the formation of villages and towns in history, the smooth implementation of planning was affected. In order to quickly and high-quality village planning, we recommend an easy-to-learn, fast, and accurate surveying and mapping method that uses the Cartesian coordinate system to control the implementation of village and township planning. Its principle is: From the planning control baseline, a right angle is the vertical axis (ordinate) of the plan, and the plan control baseline is a horizontal axis (abscissa), so as to form a rectangular coordinate system. With the principle of the rectangular coordinate system, successive measurements are used to calculate the various data required. This method has the advantages of accurate data, high speed, easy implementation, and easy learning. Here is an example: (pictured) The old street before planning forms an angle with the vertical axis of the coordinate. The included angle can be measured with a theodolite, set to α, the length of the old street, available steel
