A dataset of water bodies on the saline-alkali land in western Songnen Plain from 2016 to 2023

The dataset includes a total of 49 data files, of which (1) a total of 48 files of monthly water body data images from May to October of each year from 2016-2023 in the western saline-alkali land of Jilin, in .tif format, in which the water body image metric value is 1 and the non-water image metric value is 2; and (2) a total of 1 file of water body frequency data in the western saline-alkali land of Jilin, in 2016-2023 in .tif format, in which the closer the image metric value is to 1, representing the more times the area has been classified as a water body, and the closer the image metric value is to 0, representing the less times the area has been classified as a water body in 2016-2023. close to 1, the more often the area was classified as a water body in 2016-2023, and the closer the image element value is to 0, the less often the area was classified as a water body in 2016-2023.

本数据集总计包含49个数据文件，具体分为两部分：(1) 48个月度水体数据图像文件，涵盖2016年至2023年每年5月至10月的吉林西部盐碱地区域数据，文件格式为.tif（Tagged Image File Format）；其中图像内水体区域的度量值为1，非水体区域的度量值为2。(2) 1个吉林西部盐碱地水体频率数据文件，时间范围为2016年至2023年，文件格式为.tif；该图像中，区域度量值越接近1，代表该区域在2016-2023年间被分类为水体的次数越多，度量值越接近0，则代表该区域被分类为水体的次数越少。
