ChinaUIS Dataset
Listed in ScienceDB
This dataset is used for urban informal settlements classification.
Description
The dataset contains a total of 1833 sets of samples, each of which includes a remote sensing image of size 3×224×224 and four street view images of size 3×512×1024. The remote sensing images come from Google Earth 18-level high-resolution remote sensing image with a resolution of 1.19m.
The street view images come from Baidu Street View API. The samples in this dataset are divided into two categories, namely urban informal settlements (UIS) and non-urban informal settlements (Not-UIS). The dataset contains a total of 643 UIS samples and 1190 Not-UIS samples.
