| Abstract: | According to the algorithm of delaunay triangulation, self-adapted triangular patch division and scattered data surface interpolation, proposes a new GIS stratum simulation model. Describes the data storage structure of the model, focuses on how to attain sufficient data to represent the whole model and how to simulate the cutting section of the stratum model in any angle. |
