# NLCD-L |
|
|
This dataset incorporates both SSL4EO-L Benchmark dataset and the NLCD-L dataset which is derived from the original SSL4EO-L Benchmark dataset by combining optical data from Landsat-7 and Landsat 8-9 with NLCD ground-truth labels, originally proposed in SSL4EO-L. The dataset contains 20 MSI bands, deliberately exceeding Sentinel-2’s channel count. It comprises 17,500 training samples, 3,750 validation samples, and 3,750 test samples. |

## How to Use This Dataset |
|
|
```python |
|
|
from datasets import load_dataset |
|
|
|
|
|
# To access NLCD-L, set name to etm_oli_toa_nlcd in load_dataset function |
|
|
dataset = load_dataset("GFM-Bench/SSL4EO-L-Benchmark", name="etm_oli_toa_nlcd") |
|
|
``` |
|
|
|
|
|
Also, please see our [GFM-Bench](https://github.com/uiuctml/GFM-Bench) repository for more information about how to use the dataset! 🤗 |
