Digital geological survey and mapping techniques

Digital regional geological survey is a problem that needs urgent solution in the main in formati-zation course in geological survey and mapping.Based on the present state of the digital field geological survey and digital mapping techniques and mapping data capturing techniques in developed countries,cou-pled with the actual conditions of China,the authors discuss the field geological survey and mapping digi-tal data capturing techniques,data model,technical flow chart and tools and methods of applying digital mapping techniques for the purposes of changing the conventional mapping means ,raising the research ac-curacy and degree,accelerating the cycle of research work and changing the form of presentation of the research results.
