Application of Digital Mapping Technique in the Field Geological Practice Teaching

Digital mapping is an inevitable trend of regional geological survey in the information age,with the digital land engineering starting.It is necessary that undergraduate course practice teaching should catch up with the new social requirement that brings a reform demand to field geological practice teaching of the university.This paper introduces the basic concept of digital mapping techniques.In view of the deficiency of traditional geological mapping,based on the RGMAP digital mapping system platform popularized by CGS,the application process and technical requirements of digital geological mapping are discussed during field geological practice teaching,including three stages such as practice mobilization and preparation,outdoor practice and indoor data processing and mapping,which provides a reference for the application of field digital geological mapping in field practice teaching
