Annual maps of global urban extents between 1992 to 2020 from SRU-Net NPP-VIIRS-like nighttime light data

The dataset contains a consistent annual global urban extents between 1992 to 2020 from SRU-Net NPP-VIIRS-like nighttime light data. The pixel value is 0 or 1. 0 means non-urban, and 1 means urban. Spatial Resolution: 500m Spatial Refrence: North_Pole_Lambert_Azimuthal_Equal_Area Extent: spanning -180 to 180 degrees longitude and -65 to 75 degrees latitude. Each zip file contains an urban extent image in geotiff format. The filename of each image is "UByyyy", where "yyyy" is the year of the image.

本数据集包含基于类SRU-Net NPP-VIIRS夜间灯光数据生成的1992年至2020年逐年连续全球城市范围栅格数据。该数据集的像素值仅为0或1，其中0代表非城市区域，1代表城市区域。空间分辨率为500米，空间参考坐标系为北极兰伯特方位等面积投影（North_Pole_Lambert_Azimuthal_Equal_Area）。数据覆盖范围为经度-180°至180°，纬度-65°至75°。每个压缩文件均包含一个GeoTIFF格式的城市范围栅格影像，影像文件命名格式为"UByyyy"，其中"yyyy"代表对应影像的年份。
