So2Sat POP dataset covering 98 EU cities. The data set has two parts. Each part can be downloaded using the following links: So2Sat POP Part1 DOI: https://mediatum.ub.tum.de/1633792 So2Sat POP Part2 DOI: https://mediatum.ub.tum.de/1633795 Data set provides the predefined train/test split. Randomly selected: 80% as train (80 cities) / 20% as test (18 cities). Data set could be utilized for both classification & regression. The classes and their corresponding population range as defined in the dataset are shown in the following table.

Please note that to install rasterio and GDAL, download the binary wheels for your system [rasterio](https://www.lfd.uci.edu/~gohlke/pythonlibs/#rasterio) and [GDAL](https://www.lfd.uci.edu/~gohlke/pythonlibs/#gdal). Run from the downloads folder.
pip install GDAL-3.4.3-cp38-cp38-win_amd64.whl pip install rasterio-1.2.10-cp38-cp38-win_amd64.whl
Download the data set and add it to the current folder to run the following scripts (for both classification and regression):
skipt_train.py: To start the training eval.py: to evaluat the trained model eithet on the whole data set or on individual cities. evaluate_ghs_ours_eu.py: compute the evaluation metrics on eu cities with ghs-pop and our's predictions. evaluate_ghs_ours_us.py: compute the metrics on ghs-pop and ours prediction on us cities.
