村庄地籍调查中抵偿高程面的选择方法

为克服投影变形对村庄地籍调查精度的影响,在不采用改变高斯投影带中央经线建立独立坐标系的情况下,本文通过采用抵偿高程面、抵消投影变形、保证地籍调查精度的原理方法,针对村庄地籍调查区域广、数据量大的特点,采用直接坐标改正的方法,不需要对控制测量成果进行重新解算,可以有效、快速地实现成果纠正,在村庄地籍调查实践中应用取得了较好的效果。

The Selection Method of Compensating Level Surface on Village Cadastral Survey

In order to overcome the projection deformation to the accuracy influence of village cadastral survey,without the condition that change the central meridian of Gauss projection to establish the independent coordinate system,through the adoption of compensating level surface,offset projection deformation,ensure accuracy of cadastral survey.Expounds the principle of the method,in view of the village cadastral survey characteristics of wide area,large amount of data,using the method of directly coordinates correction,don t need to recalculation the control measurement results,and can effective and efficient realize the correct of results,in practice of village cadastral survey application obtained good effect.
