Digital  regional  geologic survey    is  urgent  to  solve  the problems in  the  main  informatization  course  in  geologic  survey  and mapping. It is the direction of  geologic  survey  and mapping  in developed countries.  Based on the present situation of digital  mapping techniques and the digital field geologic survey  and mapping capturing techniques in developed countries, the theory frame of digital mapping techniques and methods as well as  the  new   advance  capturing  techniques of digital field geologic survey  and mapping have been discussed in the paper  according to the methods of techniques  research  on the  means  of  mapping  techniques  research, the  accurate, degree and  cycle  of  research, the showing   forms of  production of  field geologic survey  and  mapping, which include the system of field geologic data capture & device (such as HPC or PDA) for capturing field geologic  data, the digital geological survey computer system, the date model of geological survey digital data, the special date model of geological survey digital data based on 3S (GIS ,GPS & RS) techniques and the flow techniques of digital mapping techniques,the tools & methods of implementing digital mapping techniques etc.
