沈阳市建成区扩展动态监测

Dynamic Monitoring of Built-up Area Expansion in Shenyang

以辽宁省沈阳市为研究对象,以该地区1995年、2000年、2005年以及2016年不同时相的遥感影像为信息源。首先,利用ENVI影像处理软件进行数据预处理;然后,对沈阳地区土地类型进行MLC监督分类并评定分类精度;最后,采用分类后对比的方法并通过Arc GIS软件对沈阳建成区扩展情况进行研究。

Taking Shenyang city of Liaoning Province as the research object,the remote sensing images of different phases in 1995,2000,2005 and 2016 were taken as the information source.Firstly,ENVI image processing software was used to preprocess the data.Then,the MLC method was applied to the land types in Shenyang area and the classification accuracy was evaluated.Finally,a method of post classification comparison was adopted,and the expansion of Shenyang built-up area was studied by ArcGIS software.
