Description from the SaRNet: A Dataset for Deep Learning Assisted Search and Rescue with Satellite Imagery GitHub Repository

• The "Note" was added by the Roboflow team.

Satellite Imagery for Search And Rescue Dataset - ArXiv

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, and is directly compatible with faster r-cnn as implemented in Facebook's Detectron2.
