Abstract:Previous geological maps always can’t keep up with the step of field work. It will reduce the efficiency of geological report substantially. All of the methods for fast mapping arisen in recent years haven’t universal adaptability. In this paper, by using MEMapGIS, fast drawing of trenching sketch maps and drilling graph maps can be realized by geological personnels. This method can improve the efficiency of drawing maps substantially, reduce errors caused by human factors at the same time and decrease personnel costs.
