| Abstract: | 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. |
