This paper introduces the classical Dijkstra algorithm in detail, and illustrates the method of implementation of the algorithm and the disadvantages of the algorithm: the network nodes require square-class memory, so it is difficult to quantify the shortest path of the major nodes. At the same time, it describes the adjacent node algorithm which is an optimization algorithm based on Dijkstra algorithm...
The information about 3D moving geographic objects are changed with the location and time, including the real-time geographic information. More and more people concern the technology of that how to collect, model, store, query, analyze and process spatiotemporal information. This paper proposes a new visualization method based on the improved MOST model, collision detection and terrain matching. The...
