Modeling technology digital geologic stratum body in the proportion of pinch in 3D GIS

Dong Zhi

Strategic Study of CAE 2010, Volume 12, Issue 2,   Pages 76-82

Abstract:

Geological prospecting data into three-dimensional system and various three-dimensional modeling methods were used to reason and connect the formation of stratum automatically to generate three-dimensional model of formation. The modeling methods can easily liberate geological workers in the field of water conservancy and hydropower from the heavy geological information access and geological interpretation of the manual labor, thus enhance the speed of three-dimensional stratum modeling and also the quality of construction.
