摘要
以某地新建化工厂选址为例,详细介绍了基于遥感和GIS的工程项目选址建模方法。该方法通过遥感获得地物的空间属性和类别特征,通过GIS的缓冲区分析、再分类、栅格叠加、归组、面积计算等空间分析与统计方法实现满足多个条件的目标区块的提取。作为选址模型的具体实现,以遥感和GIS分析软件为依托,规划出了某地适宜兴建化工厂的区块,实施了化工厂选址的遥感和GIS辅助决策。
Taking a chemical plant as an example, this paper discusses the site selecting and modeling methods of the project location based on remote sensing （RS） and GIS techniques. RS-based methods are employed for the extractions of spatial attributes and the classification of features of objects, and the extraction of multi-conditional target areas is implemented by GIS spatial analysis and statistical methods. A practical implementation of a locating model based on the above-mentioned methods with the utilization of RS and GIS analysis software is provided and investigated.
