The granite-geospatial-uki model is a transformer-based geospatial foundation model trained on HLS L30 multispectral satellite
|
10 |
+
imagery and Sentinel-1 synthetic aperture radar (SAR) backscatter over the United Kingdom and Ireland.
|
11 |
+
The model consists of a self-supervised encoder developed with a ViT architecture and Masked AutoEncoder (MAE)
|
12 |
+
learning strategy, with an MSE loss function and follows the same architecture as
|

+
[Prithvi-EO](https://huggingface.co/collections/ibm-nasa-geospatial/prithvi-for-earth-observation-6740a7a81883466bf41d93d6).

model architecture. It was pre-trained on HLS data for the continental USA, followed by additional pre-training using 16,000 HLS L30 and
|
30 |
+
Sentinel-1 images covering the United Kingdom and Ireland. The Sentinel-1 SAR backscatter (\\(\sigma_0\\)) were resampled to the same resolution
|
31 |
+
as the HLS data, and were normalized by \\(10log(\sigma_0)\\), where pixels with \\(10log(\sigma_0) > 10\\) are set to \\(10\\) and \\(10log(\sigma_0) < -35\\)
|
32 |
+
are set to \\(-35\\). The two additional Sentinel-1 bands were initialized with the mean weights of the other channels for pre-training.

The following bands were used in the pre-trained model:
