| 摘 要： | 针对数字地图的特点，探讨数字测图中的坐标变换方法，总结了一套作业思路和方法，使外业测图不需提前单独进行控制测量，且设站灵活，内业能够充分利用各种满足精度要求的测量数据和数字图进行数字化成图。配以少量控制点，该模式也可在大面积数字测图中使用。从而可减少外业工作量，显著提高工效。

| Abstract: | In this paper,coordinate transformation and height datum transformation in digitized mapping are discussed.A method is presented for large scale topographical map measurements in digital by total station instrument with coordinate transformation and height datum transformation.With the method,control surveying may be bypassed or be done after mapping and the base station can be stationed freely.The method can be used in the large area with a few control points.Other maps in digital and datum can be transformated into the new map.Some notices are given by authors in this paper,too.Therefore,much field operation will be reduced and work efficiency will be advanced. |
