A survey of land use in Lugu Lake using multispectral remote sensing

摘要

According to the assignment of land use survey in Lugu lake region based on multispectral remote sensing, firstly, this paper introduces the methods of remote sensing image enhancement, correction, fusion, interpretation and classification based on the SPOT-5 panchromatic wave band and ASTER multispectral data, secondly, statistics and analysis about the land types of the study region have been done, and evaluates the precision of the fused image classification result based on the judgment error matrix. Finally, this paper briefly evaluates the land use degree and ecological environment nvironment of the study region and points out the potential of multispectral remote sensing applied-in land use survey.
