Automatic mapping of artificialised spot from satellite images – vector – Grand-Est – 2020

This vector file corresponds to the polygonisation of the binary raster with a smoothing to reduce the “stair” effect of vectored polygons from the pixels本矢量文件对应针对二进制栅格（binary raster）进行多边形化并采用平滑处理的结果，该处理旨在降低由像素生成的矢量化多边形（vectored polygons）所产生的‘锯齿’效应（stair effect）。
