# Satellite Imagery for Search And Rescue Dataset - [ArXiv](https://arxiv.org/pdf/2107.12469.pdf)

This is a single class dataset consisting of tiles of satellite imagery labeled with potential 'targets'. Labelers were instructed to draw boxes around anything they suspect may a paraglider wing, missing in a remote area of Nevada. Volunteers were shown examples of similar objects already in the environment for comparison. The missing wing, as it was found after 3 weeks, is shown below.

The dataset contains the following:

| Set           | Images      | Annotations |

| -----------   | ----------- | ----------- |

| Train         | 1808        | 3048        |

| Validate      | 490         | 747         |

| Test          | 254         | 411         |

| Total         | 2552        |4206         |

The data is in the [COCO format](https://www.immersivelimit.com/tutorials/create-coco-annotations-from-scratch), and is directly compatible with faster r-cnn as implemented in Facebook's [Detectron2](https://github.com/facebookresearch/detectron2).
