摘　　要：数字测图是在测量工作中利用电子计算机技术将野外数据采集系统与内业机助制图系统相结合,其目标是实现信息采集处理的数字化、自动化、信息化。数字测图可以缩短作业时间,减轻劳动强度,提高成果精度。数字测图系统主要由数据输入、数据处理和数据输出3部分组成,数字测图作业模式中测记式数字测图应用最为广泛。the digitized mapping technique is to combine the field data collection system with the computer assisted mapping system in surveys by computer technology . It aims to realize the information collected and processed digitally and automaticaity. The digitized mapping technique can cut short the working time, lighten the labor intensity and enhance the precision of the productions. The system consists of three parts, such as data input, data processing and data output, the survey- record digitized mapping technique is widely used in the digitized mapping working pattem.
