# BigEarthNet Dataset

The **BigEarthNet** dataset is a large-scale benchmark Archive for remoting sensing. The dataset contains both Sentinel-2 and Sentinel-1 imagery. 

We have pre-processed the dataset by upsampling all sentinel-2 channels to 120x120 pixels and concatenated them together. Please see [Torchgeo/bigearthnet](https://github.com/microsoft/torchgeo/blob/main/torchgeo/datasets/bigearthnet.py#L385) for more information about pre-processing.

Please see our [GFM-Bench](https://github.com/uiuctml/GFM-Bench) for more information about how to use the dataset! 🙂

## Metadata

The following metadata provides details about the Sentinel-2 and Sentinel-1 imagery used in the dataset:
