【摘要】：随着高分一号卫星的成功发射,我国的空间信息产业得到了进一步的发展。GIS(Geographic Information System,GIS)在土地资源、城市路径规划、军事等领域的应用更加广泛。网络分析是地理信息系统重要的功能之一,路径分析是最基本的问题。路径分析算法、高分影像预处理质量都在影响着路径分析系统的性能,因此路径分析的研究在旅游、交通、网线的布局等方面具有重要的意义。设计以曲阳县高分一号卫星影像为底图,利用ArcGIS Desktop建立曲阳县路径模型。对常见的最短路径分析算法进行比较分析,最终选取迪杰斯特拉算法作为交通道路拓扑结构的最短路径分析算法。通过对路径模型数据存储结构的改进,实现对该算法的优化,减少了算法占用的存储空间,尤其是针对大型的数据网络模型。设计基于ArcGIS Engine组件库,以C#语言作为开发语言,最终设计出一个路径分析系统,通过选择起始结点和终点,能进行曲阳县路径网的最短路径查找分析,给出最短路径经过的结点信息和总权值,并实现模拟小车动态行驶过程。设计的实现在交通领域具有相应的现实意义。系统用到的高分数据需要经过预处理,得到带有颜色信息的高分辨率的影像。高分一号影像预处理步骤分为正射校正、配准、融合等。结合SQL Server数据库,最终完成符合要求的路径分析系统。
[Abstract]:With the successful launch of the Gaofan-1 satellite, China's spatial information industry has been further developed. GIS-Geographic Information system GIS has been used in land resources, urban path planning, Network analysis is one of the important functions of geographic information system, path analysis is the most basic problem. Path analysis algorithm and high score image preprocessing quality all affect the performance of path analysis system. Therefore, the research of path analysis is of great significance in tourism, traffic, network layout, etc. The design takes Gaofan 1 satellite image of Quyang County as the base map. The path model of Quyang County is established by using ArcGIS Desktop. The common shortest path analysis algorithms are compared and analyzed. Finally, Dijstra algorithm is chosen as the shortest path analysis algorithm of the traffic road topology. By improving the data storage structure of the path model, the algorithm is optimized, and the storage space occupied by the algorithm is reduced. Especially for the large-scale data network model, a path analysis system is designed based on ArcGIS Engine component library and using C # language as the development language. By selecting the starting node and the end point, a path analysis system is designed. The shortest path search and analysis of Quyang county path network can be carried out, and the node information and total weight value of the shortest path passing through are given. The realization of the design has the corresponding practical significance in the traffic field. The high score data used in the system need to be preprocessed. A high-resolution image with color information is obtained. The pre-processing steps of high-score 1 image are divided into orthographic correction, registration, fusion and so on. Finally, the path analysis system that meets the requirements is completed with SQL Server database.
