Application and method exploration of digital mapping system RGMAP in field measured geological sections
Digital mapping system(RGMAP)is a mobile terminal system of the digital geological survey system(DGSS)developed by China Geological Survey,which can realize the digital acquisition function of field measured geological sections.Because the mobile phone(handheld computer)GPS positioning accuracy is vulner-able to hardware and environmental factors,the data accuracy is insufficient.Based on practical work,the author briefly describes the operation process and logic of RGMAP measured profile,analyzes the differences with traditional profile measurement,and conducts three methods of testing and comparison.A set of measured profile measurement methods is summarized,which mainly uses handheld computers for field data collection,integrates RTK for coordinate measurement,and cooperates with measuring ropes to control elements such as layering,photos,and occurrence,assisting in confirming the position of elements between wires,This method can effectively improve work efficiency and data accuracy.
