【摘要】 在地理信息系统中需要处理的数据量越来越大的趋势下,提高软件代码的执行效率变得非常重要。论文介绍并讨论了利用编译器进行代码优化的各种情况;并采用地理信息系统中的一些空间分析的功能进行了测试。实验表明采用这种方法,提高了程序的运行速度,增强了程序分析处理数据的能力。更多还原

【Abstract】 With the trend of GIS data being larger and larger,improving the computing efficiency of software becomes very important.Several conditions of code optimization using the compiler have been introduced and some spatial analysis functions in GIS have also been used to test the improvement in efficiency in this paper.Experiment shows that using compiler optimization enhances the capability of data processing and improves GIS software’s speed.更多还原
