Stratum Segmentation with Tetrahedrons and Its Data Organization
Guiying Zhang · Geo-information Science · 2007
In this paper, discontinuous stratum is partitioned into tetrahedrons for better representation and analysis of its inner structure. In the process, topological relationships of the spatial primitive data objects, such as nodes, edges, faces and voxels, are carefully designed and decomposed topologically at different levels. An object-oriented object manager is proposed to manage these spatial data. Considering the object manager, appropriate data structure and efficient indexing are adopted to organize the spatial objects so as to accelerate the process of confirming the uniqueness of any topological object in the storage list. With the object manager, both the generation of different levels of topological objects and the spatial inquiry efficiency are greatly improved. A case study proved that this method is efficient in real stratum segmentation.
