Wavelet multi-resolution remote sensing image analysis of characteristics of pyramid model of dynamic reconfiguration
District, for the section of the city complex to be effective. After the search in the process, the need to determine whether the node to search the shortest path to the vertex already exists in the collection. If the node does not exist in the set of vertices in the shortest path, the search process in accordance with the first approach to fill in the node information to the shortest path tree. If the node already exists in the set of vertices in the shortest path, you need to compare the end of the second search node information corresponding to the shortest path tree node information,[link widoczny dla zalogowanych], specifically, this search process will be obtained from the source to the shortest path distance of the point value and the corresponding shortest path tree nodes Length compared to the value, if the latter is small you do not need to modify any information directly into the next search process, if the former is smaller, you need to modify the original shortest path tree node. Table 1 The three experimental parameters obtained for solving the shortest path algorithm 5 Conclusion 4 of the algorithm in an economic development zone be achieved on the road network map. Economic Development Zone of a road network map 371 total nodes, edges 653. In ArcOb-jects in the VBA environment,[link widoczny dla zalogowanych], VB + ArcObjects programming by way of logic control by the VB algorithm, ArcMap manage graphics display and control, to achieve dynamic display in the graphics window, the shortest path obtained, and the composition of the shortest path selected sections of the collection process. Implementation process flow chart in Figure 2 Figure 2: Economic Development Zone in the road map of a selected three groups of arbitrary nodes, the shortest path to solve three separate experiments, the derived parameters in Table 1. Three experimental results shown in Figure 3. From Table 1 and results can be seen in Figure 3: In this paper, the shortest path algorithm can solve the whole story specified the shortest path between points, not only suitable for a test ... c test three experimental effect diagram in Figure 3 three times in the GIS network analysis practical applications,[link widoczny dla zalogowanych], due to different circumstances require different on the shortest path, such as the time between two points using the shortest, least expensive and so on. At this time, just the algorithm object for each of the weight of arc from the arc length changes for the time,[link widoczny dla zalogowanych], costs can be.
