This repository is official implementation of 'A human-machine collaborative approach measures economic development using satellite imagery'.
To train the scoring model siScore, you need to follow three stages: Stage1, Stage2, Stage3.
Stage1 first conducts pre-training, and then generates the clusters from given satellite imagery via DeepCluster.
Stage2 suggests ensemble method for aggregating human-guided weak-supervision in reasonable way. Humman annotators first label the partial orders between the clusters from Stage1. Then, the Machine ensembles the all labels from the human, and prune some clusters for better training.
Stage3 trains the rank-wise score model siScore from the Stage2's label (Ensemble POG).
Please refer to README.md in each stage's directory (i.e., Stage1, Stage2, Stage3) to get started.
Dataset in data directory is sampled example from the original dataset. The code is implemented according to its format, so use them just for the reference.

Original data here (2016~2019)
(A) Prediction scores over grid images averaged over four years from 2016 to 2019, (B) shows the yearly aggregated VIIRS nightlight data in 2019, and (C) shows the land cover classification map released by the South Korean Government in 2019. The zoomed-in views in (D–F) compare predictions for Sepho County in the Kangwon region. From left to right are the Sentinel-2 satellite images taken in 2019 (D), model predictions (E), and manually verified buildings colored red from the building footprint data in 2014 (F).

This code has been tested and confirmed to be reproducible with 
Also, all code has been tested on the following environment (as we wrote in requirements.txt):
torch==1.11.0
torchvision==0.8.2
numpy==1.19.2
scipy==1.6.2
sklearn==0.23.2
scikit-image==0.19.2
pandas==1.1.4
geopandas==0.10.2
Pillow==8.2.0
opencv-python==4.7.0.72
faiss-cpu==1.7.3
faiss-gpu==1.7.2
However, certain module versions may cause dependency issues (as of April 11, 2023).
Therefore, I suggest following the command below:
conda install pytorch==1.13.1 torchvision==0.14.1 pytorch-cuda=11.7 -c pytorch -c nvidia
pip install scipy scikit-learn scikit-image geopandas opencv-python faiss-cpu faiss-gpu
The overall progress will take less than 30 minutes for the normal desktop computers.
GPU spec : 4x NVIDIA TITAN Xp
OS : linux 4.4.0-190-generic
