According to the degree of pavement coverage, the labeled roads include both track-covered and non-track-covered pavements. Based on the physical perspective of geographic factors, the marked roads include railroads, highways, urban roads and rural roads.CHN6-CUG contains 4511 labeled images of size 512×512, divided into 3608 for model training and 903 for testing as well as result evaluation with a resolution of 50 cm/pixel. The original image of the dataset is in .jpg format and the road labeling image is in .png format, and the compressed data size is 175 MB.
