Abstract: 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.
