This repository is the official implementation of the paper'ROAD NETWORK EXTRACTION FROM SATELLITE IMAGES USING CNN BASED SEGMENTATION AND TRACING'(IGARSS 2019).

To install requirements:

pip install -r requirements.txt
tensorflow
rtree
numpy

For generating the dataset, please refer to RoadTracer for more details.

• Corner/corner_detection.py : generating the starting points for further road tracing.
• Tracer/: tracing the road centerline from these starting points. Some of them are modified from RoadTracer.

To train the model(s) in the paper, run this command:

python train.py --input-data <path_to_data> --alpha 10 --beta 20

📋 Describe how to train the models, with example commands on how to train the models in your paper, including the full training procedure and appropriate hyperparameters.
