Land Use Change Monitoring in Angkor Wat Based on Tiangong-2 Wide Band Imaging Data
Angkor Wat is one of the most important archaeological sites in the world. However, due to its changes in natural environment and human activities, the Angkor Wat and its surrounding environment are facing great challenges. We select the data of Tiangong-2 Wide-band Imaging Spectrometer in 2017 and 2018 and to obtain the land use in Angkor area with the use of the maximum likelihood method. By analyzing the change information within one year, the monitoring application of the Angkor Wat and its surroundings is carried out. The results show that the overall accuracy is about 82.7% and the urbanization and tourism blowout have caused the over-exploitation of the resources of Angkor Wat and its ecological imbalance. The area of forest greatly reduced and was converted into urban and agricultural land; the agricultural land increased greatly, and it has continued to expand to the Angkor heritage area. The urban area around the heritage has increased. Tiangong-2 Wide-band Imaging Spectrometer is capable for land cover classification, and can provide important information to support the protection and sustainable development of various heritages.
