1公里分辨率世界居住区足迹2015面积百分比数据集

该数据集为世界居住区足迹（WSF）2015图层的1公里重采样版本，每个像素值代表对应1公里网格内居住区覆盖的地表面积百分比。产品以单文件GeoTIFF格式分发（采用EPSG4326投影坐标系与紧缩压缩算法），并内嵌2、4、8、16、32、64、128及256倍率的金字塔概览图层。

This dataset is the 1-kilometer resampled version of the World Settlement Footprint (WSF) 2015 layer. Each pixel value denotes the percentage of the land surface covered by settlements within the corresponding 1-kilometer grid cell. It is distributed as a single-file GeoTIFF that adopts the EPSG:4326 projected coordinate system and the deflate compression algorithm, and embeds pyramid overview layers with zoom ratios of 2, 4, 8, 16, 32, 64, 128 and 256.
