World Settlement Footprint (WSF) 2015

The World Settlement Footprint (WSF) 2015 is a 10m (0.32 arc sec) resolution binary mask outlining the 2015 global settlement extent derived by jointly exploiting multitemporal Sentinel-1 radar and Landsat-8 optical satellite imagery.
The archive is organized for download in 306 GeoTIFF files (EPSG4326 projection, deflate compression) each one referring to a portion of 10x10 degree size (~1110x1110km) whose upper-left and lower-right corner coordinates are specified in the file name [e.g., the tile WSF2015_v1_EPSG4326_e010_n60_e020_n50.tif covers the area between (10E;60N) and (20E;50N)].
A virtual mosaic file (i.e., WSF2015_v1_EPSG4326.vrt) is also provided which allows visualizing the global product at once on most diffused GIS platforms (e.g., ArcGIS, QGIS, MapInfo). Settlements are associated with value 255; all other pixels are associated with value 0.

世界人居足迹（World Settlement Footprint, WSF）2015数据集是一款分辨率为10米（0.32角秒）的二值掩膜产品，用于勾勒2015年全球人居活动范围，其研发通过联合利用多时相Sentinel-1雷达影像与Landsat-8光学卫星影像完成。
该数据集档案以306个GeoTIFF文件形式提供下载，采用EPSG4326坐标系与deflate压缩格式。每个文件对应一块10×10度（约1110×1110千米）的影像区块，区块的左上角与右下角坐标直接标注于文件名中。例如，瓦片文件WSF2015_v1_EPSG4326_e010_n60_e020_n50.tif覆盖的区域为东经10度、北纬60度至东经20度、北纬50度之间的范围。
同时还提供了虚拟镶嵌文件（即WSF2015_v1_EPSG4326.vrt），可在主流GIS平台（如ArcGIS、QGIS、MapInfo）中直接可视化全球完整数据集。其中，人居区域的像素值为255，其余所有像素的像素值均为0。
