测绘仪器随着科学技术的发展，尤其是电子技术的发展，由机械光学发展到光学电子（如全站型仪器），乃至全电子型仪器（如GPS），其功能越来越全，测量精度越来越高，适宜条件越来越宽，应用范围亦越来越广，操作越来越简便，价格亦越来越昂贵，少则几万元，多则数十万元。如果 Surveying and Mapping Instruments With the development of science and technology, especially the development of electronic technology, the development of mechanical optics to optical electronics (such as station type instruments), and even all electronic instruments (such as GPS), its functions become more and more full, measurement accuracy Higher and higher, suitable conditions more and more wide, the scope of application is also more and more widely used, more and more easy to operate, the price is more and more expensive, ranging from tens of thousands, as many as several hundred thousand dollars. in case
