摘要
Three dimensional geographic information system (3D GIS) and multiple scale national fundamental geographic information data were used to survey the superficial strata attitude with the support of computer system. This method can be used to replace the traditional field survey method. So in this scene, with the digital elevation model data and high-resolution remote sensing images, the real three-dimensional geographic scene is build. The results select and survey multiple points and their coordinates by means of human-computer interaction by measuring the spatial coordinate of multiple points (over 10 points) on the strata and using least square method to solve the fitting planar of these measured points, a practical method for obtaining the solution of the shallow bed attitude was making use of 3D GIS.
