摘　　要：论述了建立独立坐标系时中央子午线及投影面的选择与各地区投影长度变形值的关系,说明了尽量利用原有坐标系统的重要性。建立台州市首级平面控制网时,通过坐标转换,充分利用旧有资料,既满足了精度要求,又节约了资金,为同类工程提供了借鉴。The relation between central meridian & projection plane choice and the distortion value of projection length of areas was discoursed on, and then the essentiality to make use of intrinsic coordinate system was explained. Through coordinate conversion, making use of former data, not only enables the method to satisfy precision requirement and economize capital, and offer lessons from experiment for reference of engineering alike.

关 键 词：控制网改造 中央子午线 独立坐标系 坐标转换 台州市
