Remote Sensing Monitoring of Surface Area Change of Qinghai Lake from 2013 to 2018
Abstract
Qinghai Lake, located on the Qinghai-Tibet Plateau in China, is the highest and largest inland lake in geography. This paper takes
Qinghai Lake as the research object and Landsat 8 OLI_TIRS remote sensing image as the data source to obtain image data of Qinghai Lake
from 2013 to 2018. NDWI (Normalized Differential Water Body Index) method is used to extract water body information, and then statistics
the area change from 2013 to 2018. The experimental results show that the surface area of Qinghai Lake has an overall increasing trend in
these five years.
