Code of the following manuscript:

'Detecting Urban Changes With Recurrent Neural Networks From Multitemporal Sentinel-2 Data'

https://arxiv.org/abs/1910.07778

Steps

1. Preprocessing with preprocess.py

Create a folder (e.g 'images') of the raw data with the following structure:

/ images / city / imgs_i / (13 tif 2D images of sentinel channels)

where i=[1,2,3,4,5]

and city = ['abudhabi', 'aguasclaras', 'beihai', 'beirut', 'bercy', 'bordeaux', 'brasilia', 'chongqing', 'cupertino', 'dubai', 'hongkong', 'lasvegas', 'milano', 'montpellier', 'mumbai', 'nantes', 'norcia', 'paris', 'pisa', 'rennes', 'rio', 'saclay_e', 'saclay_w', 'valencia']

Use preprocess.py to preprocess the images of the OSCD dataset.

2. Create csv file with (x,y) locations for patch extraction during the training process using make_xys.py

Here you need to specify the folder with the OSCD dataset's Labels.

Note that 'train_areas' list should be defined in the same way both in make_xys.py and main.py

3. Start the training process with main.py

4. Make predictions on the OSCD dataset's testing images with inference.py

Comments are included in the scripts for further instructions.
