6. Conclusions In order to solve the problem that heuristic-based algorithms may cause high approximation error, this paper presents an Optimal Trajectory Simplification Algorithm based on Graph Model (OPTTS). First, the optimal solution is defined as the compression schema with the minimum number ...
For comprehensive background reading, please refer to the referenced paper [20]. The primary operators that differ from DL are shown in Table 1. Diagrams are supplied to illustrate the graphic meanings of the operators related to geographic objects and their relationships. A top concept indicates ...
