青藏高原湖泊面积长时间序列数据集(1970-2013)
收藏资源简介:
青藏高原湖泊面积长时间序列数据集包含1970s至2013年364个面积大于10平方公里湖泊的面积序列数据。根据Landsat影像得来,以Landsat 10月份数据为主,每隔3年取一个数据,减少季节变化的同时,可利用数据达到最大。 数据使用NDWI水体指数提取,每个湖泊经过人工目视检查与编辑。 数据应用于青藏高原湖泊变化、湖泊水量平衡、气候变化的研究。 数据类型:矢量。 投影方式:WGS84。
The long-time series lake area dataset for the Tibetan Plateau includes area sequence data of 364 lakes with an area greater than 10 km², covering the period from the 1970s to 2013. Derived from Landsat imagery, the dataset primarily uses Landsat data acquired in October, with one data point collected every three years to minimize seasonal variations while maximizing the available data volume. Lake areas were extracted using the Normalized Difference Water Index (NDWI), and each lake was manually visually inspected and edited. This dataset has been applied to studies on lake changes, lake water balance, and climate change over the Tibetan Plateau. Data type: Vector. Projection: WGS84.
