数字高程模型在大型信息系统试验选址中的应用

Application of Digital Elevation Model in Site Selection of Large Scale Information System Test

大型信息系统试验选址是试验准备工作中的关键问题,关系到整个试验的成败。传统选址方法存在效率低、不准确等不足。本文提出了一种利用数字高程模型完成试验选址的方法。与传统选址方法相比,该方法具有高效、可靠的优势。首先利用层次分析法建立选址准则,利用选址准则对数字高程模型进行空间分析,最后确定符合试验要求的选址。本文以一大型系统试验选址为例,验证了该方法的可行性。

The site selection of large scale information system test is the key issue in test preparation. It relates the success or failure of the test. Traditional site selection has many disadvantages, such as low efficiency and unreliability. This paper raises a test site selection method based on digital elevation model. Compared with traditional method, this method has the advantages of high efficiency and reliability. The site selection criteria are established by analytic hierarchy process. And the criteria are used to analyze the digital elevation model to identify suitable sites. This paper verifies the validity of the method through site selection in an information system test.
