Abstract & Keywords
Abstract: In terms of Google Earth Engine (GEE) platform, we adopted the method of image composite and use Landsat historical images to generate seasonal images with lowest cloud composite at the pixel level. Based on a water index method and correctness procedure, we obtained 11 series of Qinghai Lake water body periphery during 1987–2017 in this research through manual modification and validation by making use of generated seasonal image data. The dataset has a long time series and geometric properties of the lake, which can be used as the basic data for assessing the temporal-spatial changes of the lake and the changes in water capacity of the lake. In addition, it can also be used as an important reference for the research on changes of water resource, the relationship between climate change and lakes.
Keywords: Qinghai Lake; lake body periphery; area changes
