High Resolution Semantic Change Detection Dataset

HRSCD Example

The Dataset

This dataset contains 291 coregistered image pairs of RGB aerial images from IGS’s BD ORTHO database. Pixel-level change and land cover annotations are provided, generated by rasterizing Urban Atlas 2006, Urban Atlas 2012, and Urban Atlas Change 2006-2012 maps.

The dataset is split into five parts:

The 2006 images are under a non-redistributable licence, but can be downloaded directly from IGN’s website ( https://geoservices.ign.fr/documentation/diffusion/telechargement-donnees-libres.html#bd-ortho-50-cm or https://www.geoportail.gouv.fr/carte). The necessary files are:

Labels

Change labels are available for all image pairs in the dataset. Available classes:

Land cover maps are available for all images in the dataset. Urban Atlas classes have been grouped at first hierarchical level, as described in the paper cited above. Available classes:
