资源简介:
在Google Earth Pro 中对1984~2018年时间段中1984、1990、1996、2002、2008、2014、2018七期的高分辨率影像进行目视解译,依据地表水在研究区内的分布比例选取56个水域样本点,将样本点中70%作为训练样本,30%作为验证样本
In Google Earth Pro, visual interpretation was conducted on high-resolution remote sensing images of seven phases (1984, 1990, 1996, 2002, 2008, 2014 and 2018) spanning the period from 1984 to 2018. A total of 56 water body sample points were selected based on the distribution proportion of surface water within the study area, among which 70% were designated as training samples and the remaining 30% as validation samples.
