基于上述认识,本文主要阐述了Shape数据中shp文件、shx文件、dbf文件的存储方式和组织形式,其中最主要阐述了shp文件的解析过程和描画过程,其中包括对point型记录的解析,对polyline型记录的解析,对polygon型记录的解析,解析之后通过描画过程把Shape数据展示给用户,同时用户可以查看Shape数据中包含的属性信息。而且用户也可以通过鼠标对图像进行简单的操作。
本文首先介绍了Shape数据的数据结构,并对系统做了需求分析。然后运用模块化的思想对系统进行设计,叙述了每个模块的详细设计和实现方法,通过对系统的测试,对其功能进行了评估,最后,进行了总结,介绍了系统的不足之处,指出了应该改进的方面。
In recent years, the automobile industry has become our country's pillar industry, the automobile in the daily life the function is also getting more and more prominent. But how to realize each kind of vehicles' effective direction, the coordination control and the management already became an important question which the transportation and the safety control department faced. Demonstrated according to the statistical data that the Western developed country direct and the indirect economic loss which creates as a result of the road jamming is very astonishing. Therefore to satisfy the enhancement transportation efficiency and the safety control need, various countries one after another have developed to the automobile guidance system's research and the development. In the automobile guidance system, the electronic map data is in the core position. Any guidance aspect's application is based on with draws to the map data analysis realizes. However the science and techn
