Research on Surveying and Mapping Technology Based on 3D Digital Topographic Map
By using computer technology to carry out surveying and mapping work,not only it can improve the efficiency of surveying and mapping,but also can reduce the cost of investment.Therefore,this paper makes an in-depth analysis of the current 3D digital mapping technology.In this paper,the concept and characteristics of 3D digital topographic map are introduced firstly,and then the concrete content and implementation flow of this technology are introduced.Finally,the paper discusses how to achieve this goal effectively,so as to ensure that the results of surveying and mapping have a strong practical value.
