500米分辨率中国2020-2024年烧毁面积数据集
收藏资源简介:
本数据集基于中分辨率成像光谱仪(MODIS)的MCD64A1产品,生成了覆盖中国全境、时间跨度为2000年至2024年的烧毁面积数据。数据集采用MCD64A1标准算法,该算法通过结合MODIS地表反射率数据和主动火点信息,利用燃烧敏感植被指数与未燃烧参考像元之间的时序变化,来识别和绘制火烧迹地。数据集在空间上覆盖中国全域,空间分辨率为500米,时间分辨率为逐月。
This dataset generates burned area data covering the entire territory of China, spanning from 2000 to 2024, using the MCD64A1 product of the Moderate Resolution Imaging Spectroradiometer (MODIS). The dataset employs the standard MCD64A1 algorithm, which combines MODIS surface reflectance data and active fire point information, and identifies and maps burned areas by leveraging temporal variations between burn-sensitive vegetation indices and unburned reference pixels. Spatially, this dataset covers the entire territory of China, with a spatial resolution of 500 meters and a monthly temporal resolution.
