Since the founding of our state , not only economic developed prosperity , but also the accuracy and continuous of surveying and mapping instruments of our country improved constantly and automation degree are higher, which not only change the traditional measuring method for surveying and mapping work, it is a qualitative leap. Surveying and mapping instruments in China after decades, from the traditional to the modern surveying and mapping instruments of surveying and mapping instruments evolution. The 1950 s surveying and mapping instruments developed in various types of electromagnetic wave rangefinder, electromagnetic wave the ranger survey localization method by triangle measuring method of the extended to traverse survey precision and trilateral measuring method. At the same time the emergence of electronic computers will also measure speed greatly ascend, surveying and mapping data through the computer operations become more accurate and quick. The development of the technology of satellite space greatly promote the surveying and mapping instruments and the development of the surveying and mapping work. These traditional surveying and mapping i
