城市交通最佳路徑選擇及最佳點(diǎn)選擇的算法分析與設(shè)計(jì)
[Abstract]:As we all know, information and information system is a very important part of modern society, it has almost penetrated into all levels of human society, and has a profound impact on the development of human society. Geographic Information system (GIS:GeoGraphical Information System or Geo-Information System), as a branch of information system, is developed gradually under the background of this era, providing policy managers and ordinary users with decision support. To solve real affairs. In this paper, combining with GIS spatial analysis theory, database theory, analysis model and so on, the problems that should be paid attention to in the course of map vectorization and how to choose the best path and the best point on the electronic map are discussed. The analysis and design of the algorithm are given. The main research contents include: the purpose and significance of the algorithm, the process and emphasis of map vectorization, the traditional shortest path algorithm, the innovative best path algorithm and its analysis, the design, the traditional optimal point algorithm (point selection algorithm); Innovative optimal point algorithm and its analysis, design; design of spatial data structure to satisfy the related algorithm; implementation and testing of algorithm and so on.
