1985年10月亚洲南美洲典型Ramsar内陆5km湿地逐月制图

亚洲南美洲典型内陆湿地制图，时间为1985年10月，空间分辨率为5000m，包含内陆湿地和其他共两类。针对RAMSAR湿地名录中的典型湿地（包括玛米洛阿自然保护区、帕拉河-莫科里托河之间地区、叶尼塞河河口布洛克霍夫斯基群岛和帕斯塔萨河流综合体），采用1985年10月的AVHRR的月平均影像数据和高程数据，利用AVHRR月平均数据的波段计算植被指数，然后把植被指数、反射率数据和高程数据输入到已经经过样本训练得到的分类器中，得到内陆湿地制图结果。This dataset is intended for mapping typical inland wetlands in Asia and South America, with a temporal coverage of October 1985 and a spatial resolution of 5000 meters, consisting of two categorical classes: inland wetlands and others. Targeting the typical wetlands listed in the Ramsar Wetlands Inventory, including the Mamilloa Nature Reserve, the area between the Pará River and the Mokorito River, the Blockhovsky Islands at the mouth of the Yenisei River, and the Pastaza River Complex, the dataset employs monthly average AVHRR image data and elevation data from October 1985. Vegetation indices were calculated using the spectral bands of the AVHRR monthly average product. Subsequently, the vegetation indices, reflectance data and elevation data were input into a classifier pre-trained on sample datasets to produce the final inland wetland mapping results.
