摘　　要：阐述了在地形复杂、地貌破碎、作业组较多时一种改良的数字化测图新方法的作业流程。该方法发挥了数字化测图的高精度高效率和模拟法测图善于处理勾绘复杂地貌等高线的长处,为针对不同情况制定合适的测图作业方案增加了一种选择。We present an improved method that combines the traditional analog mapping with the digitalized mapping to deal with the difficulties occurred in the mapping area with abnormity topographic features, complex terrain and multiple working parties taking part in. In the field a surveyor uses the total station instrument to collect the data of a map and at the same time draws a sketch with hands. In the office, scan the sketch to obtain a digital sketch. By using the CASS 5.0, adjust scale and direction of the digital sketch and then combine it with the sketch from the total station. The whole mapping process by using this method is of advantage of the high precision, efficiency and easy to map. It provides a choice to make appropriate projects of measurement in different situations.
