LEVIR-CD

We have supplemented geospatial information (e.g., latitude and longitude coordinates) for each sample in LEVIR_CD. Specifically, we provide a .geojson file and a .json file, both of which contains the correspondence of the sample name and the geospatial location. Files can be seen in the LEVIR_CD_spatial_info folder.

Here, we give more details about these files.
