Cover and Achieve the Digital Code to the CASS Field Operational Code System Design
The author based on years of digital mapping practice,based on coding rules and advantages and disadvantages of several ma-instream applications that are currently widely used data encoding and CASS field operational code coding scheme with comparative analysis,the author propose a new coding scheme suitable for Total station and GNSSRTK to data acquisition——digital encoding scheme. The coding method is easy to learn,all digital encoding,simple coding method,clear meaning and easy to remember. It uses easy to input,high field col-lection efficiency,it is an efficient all digital mapping encoding method. The article discusses the conversion achieve method and programming of digital code to CASS field operational code use VS.NET.
