近年来,公路控制测量中普遍采用GPS测量,多数测绘单位都是按照国家控制测量的方法和要求进行布设、测量,没有考虑公路测量的特殊性。这样就存在一个问题:施工单位现场用全站仪实测某两点之间的距离与用坐标反算的距离相差很大,无法满足作为工程施工的要求。针对这一问题,本文就如何建立公路控制测量坐标系的方法进行探讨。 更多还原

【Abstract】 Road control survey in many surveying and mapping industry,in recent years,are using by GPS according to national control survey’s methods and requirements.Without the consideration for the survey specificity,there is a great distance between field measurements by total station measured and coordinates inverse calculation.For such the issue,the method for establishment road control measure coordinates is discussed. 更多还原
