Automatic mapping of artificialised spot from satellite images – binary raster 10 m – Grand-Est – 2021

Raster at 10 m resolution, binarisee version of the frequency file of occurrence of urban. Binarisation is carried out with a 50 % threshold and allows to define 2 non-urban classes (0) and urban (1). Each pixel was imaged between 7 and 62 times.本数据集为10米分辨率的栅格（Raster）数据，是城市出现频率文件的二值化版本。本次二值化处理以50%作为阈值，据此划分出两类地物：非城市类（取值为0）与城市类（取值为1）。所有像素的成像次数介于7至62次之间。
