<正>利用坐标变换解决了两个不同坐标系之间的换算问题，使得在道路工程、建筑工程中的定位测量快速、简捷，并突破了常规施工放样，即：利用旋转后坐标系——施工坐标系（Ｈ，Ｖ）进行施工放样。

The conversion between different coordinate systems is solved by using coordinate transformation. This would make a fast and concise location survey for road engineering and architectural engineering, breaking through the conventional construction layout. The construction layout is carried out by using a postrotated coordinate system,i. e, a construction coordinate system(H,V)．
