Mapgis digital terrain model system in the application of geological prospecting data mapping

In this paper,by using the grid interpolation function of digital terrain model subsystem in the Mapgis6.7 platform,we interpolated the water inrush coefficient,and got the water inrush coefficient contour map and water-based partition map.The author introduced this method concretely.The method can achieve rapid data graphical method simply and accurately,and has significant practical application value.
