Abstract 

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.

About:

 

Dataset described in: 

Daudt, R.C., Le Saux, B., Boulch, A. and Gousseau, Y., 2019. Multitask learning for large-scale semantic change detection. Computer Vision and Image Understanding, 187, p.102783.

 

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:

    - 2006 images 

    - 2012 images

    - Change labels

    - 2006 land cover maps

    - 2012 land cover maps

 

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-donnee... or https://www.geoportail.gouv.fr/carte). The necessary files are:

    - BD ORTHO® 50 cm, D 14 - CALVADOS, 2005

    - BD ORTHO® 50 cm, D 35 - ILLE-ET-VILLAINE, 2006

For help with downloading the images please contact the authors.

 

================================================================================

Labels:

 

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

    - 0: No change

    - 1: Change

 

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:

    - 0: No information

    - 1: Artificial surfaces

    - 2: Agricultural areas

    - 3: Forests

    - 4: Wetlands

    - 5: Water

Comments

The - BD ORTHO® 50 cm, D 14 - CALVADOS, 2005 and  - BD ORTHO® 50 cm, D 35 - ILLE-ET-VILLAINE, 2006 datasets do not appear on the linked IGN webpage provided.  Additionally the Geoportail provided is difficult to navigate for those of us who don't speak French.  Is there an updated webpage I can access these datasets at?  Thank you in advance.

As stated in the dataset description, we do not have the redistribution rights for the 2006 images. Please contact us by email for further help in downloading these images.

Have you got the image data for 2006?

Submitted by qiu ru ren on Mon, 07/06/2020 - 06:16

The 2006 images appear to be missing

All change labels files appear to be blank or else are only comprised of 0's (i.e. "no change").  Is there a way to fix this?

Some people have contacted me with this problem, and it seems that OpenCV sometimes fails to load the labels correctly, I don't know why. Below is a python program you can run to test if the images are corrupted. The output should contain mostly ones and a few zeroes.

 

 

import skimage.io as io

from glob import glob

files = glob('change/*/*.tif')

for f in files:

    I = io.imread(f)

    print(I.max())

Using This dataset, is their a sample project available for semantic change detection. Kindly share any github page, that would be helpful for my research work.

Hi Rodrigo,

The datset looks not correct. The 2006 & 2012 Lancover maps are missing. Also Tiff images present in 2006/2012/change folders all looks simillar. Can you provide the correct dataset and GIThub page Simillar to OSCD dataset. 

Thanks,

Visa
