Application of multi-temporal TM (ETM+) image in monitoring mining activities and related environment changes: A case study at Daye, Hubei, China

摘要

This paper presents a case study ofDaye, Hubei, China, to trace the mining activities and related environment changes during the past 10 years, with an emphasis on land cover changes. The TM (ETM+)satellite data has been used in this case study. A multi-temporal dataset consisting of two Land sat 5 Thematic Mapper (TM) images and one Enhanced Thematic Mapper Plus (ETM+) image including 1986, 1994 and 2002 have been used to compare the land cover changes of the Daye area, Hubei Province, China.
