摘要
根据工程测量中长度投影变形超过2.5 cm/km时应建立地方工程控制网的要求,讨论了工程坐标系统建立的一般方法,以及不同工程坐标系间的坐标转换、工程坐标系与国家1954年北京坐标系间的坐标换算,并通过实例进行了验证。
Based on the requirement that when length distortion of projection excesses 2.5 cm/km, the local engineering control network should be established, this paper discusses the general method to establish engineering coordinate system, and the coordinate transformation among different engineering coordinate systems, and the transformation between the engineering coordinate system and Beijing geodetic coordinate system 1954, and verified by through an example.
