Deep Learning for Rare Energy Infrastructure in Satellite Imagery (2020-2021)
Key stakeholders in electrification planning processes often do not have up-to-date information on energy infrastructure, limiting energy access planning efforts. Additionally, traditional methods of collecting this locational data, such as on-ground surveys, are time-consuming and expensive.
This project is part of a larger effort to develop detailed, up-to-date maps of energy infrastructure by using deep learning techniques that can automatically and rapidly scan massive volumes of remotely sensed data, such as satellite imagery. Deep learning approaches provide a powerful tool for researchers, policy-makers and governments to continuously collect energy systems information and make informed decisions about providing electricity to underserved communities.
The 2020-2021 team demonstrated the effectiveness of using synthetic imagery to enhance the ability of energy infrastructure detection algorithms to automatically map the locations of infrastructure across diverse geographic domains by creating synthetic overhead imagery that supplements real training data.
Synthetic images can be made rapidly and cheaply, and come with automatic labels for the objects. The team created an efficient pipeline for synthetic data generation that can be applied to many different types of energy infrastructure. Experiments focused on wind turbines, but the model can be expanded to other types of infrastructure.
Team members conducted a set of experiments to test the impact of augmenting the training dataset with synthetic data and found that synthetic imagery data significantly improved the model’s performance accuracy and generalizability. Results show that adding synthetic imagery can be particularly useful when training data is limited and when it is cost-prohibitive to collect and label more data for the region of interest.
