Here is a **technical `README.md`** for your dataset, tailored for fine-tuning an ESRGAN model using Sentinel-2 (low-res) and NAIP (high-res) imagery:

## π¦ SAT\_ELITE\_DATA
|
| 9 |
+
|
| 10 |
+
**SAT\_ELITE\_DATA** is a curated paired-image dataset intended for training and fine-tuning super-resolution models, particularly **ESRGAN (Enhanced Super-Resolution Generative Adversarial Network)**. The dataset consists of aligned low-resolution and high-resolution image pairs, sourced from **Sentinel-2** (10m/pixel) and **NAIP** (1m/pixel) satellite imagery, respectively.

### π°οΈ Dataset Overview
|
| 15 |
+
|
| 16 |
+
| Domain | Source | Spatial Resolution | Description |
|
| 17 |
+
| -------- | ---------- | ------------------ | -------------------------------------------- |
|
| 18 |
+
| Low-Res | Sentinel-2 | 10 meters/pixel | Multispectral satellite imagery (RGB subset) |
|
| 19 |
+
| High-Res | NAIP | 1 meter/pixel | Aerial imagery from USDA's NAIP program |
|
| 20 |
+
|
| 21 |
+
The dataset is organized to support **paired image super-resolution tasks**, where each Sentinel-2 patch (input) corresponds spatially and temporally to a high-resolution NAIP patch (target output).
|
| 22 |

### π Directory Structure
|
| 26 |
+
|
| 27 |
+
The dataset is provided as two zip files:
|
| 28 |
+
|
| 29 |
+
```
|
| 30 |
+
SAT_ELITE_DATA/
|
| 31 |
+
βββ train_set.zip # Paired training images
|
| 32 |
+
βββ val_set.zip # Paired validation images
|
| 33 |
+
```
|
| 34 |
+
|
| 35 |
+
Each zip contains two folders:
|
| 36 |
+
|
| 37 |
+
```
|
| 38 |
+
train_set/
|
| 39 |
+
βββ lr/ # Low-resolution Sentinel-2 images (input)
|
| 40 |
+
βββ hr/ # High-resolution NAIP images (target)
|
| 41 |
+
```
|
| 42 |
+
|
| 43 |
+
The same structure applies to `val_set/`.
|
| 44 |
+
|
| 45 |
+
Each image pair shares the same filename (e.g., `12345.png` in both `lr/` and `hr/`), making it straightforward to load matching inputs and targets during model training.

### π― Use Case
|
| 59 |
+
|
| 60 |
+
This dataset is designed for:
|
| 61 |
+
|
| 62 |
+
* Super-resolution model training (e.g., **ESRGAN**, **EDSR**, **SRGAN**)
|
| 63 |
+
* Remote sensing image enhancement
|
| 64 |
+
* Satellite-to-aerial domain transfer learning
|
| 65 |
+
* Visual fidelity and detail recovery in earth observation pipelines
|
| 66 |
+

+
### π§ Suggested Training Pipeline (ESRGAN)
|
| 70 |
+
|
| 71 |
+
1. **Preprocessing:**
|
| 72 |
+
|
| 73 |
+
* Resize Sentinel-2 images to match HR resolution using bicubic interpolation (if needed)
|
| 74 |
+
* Normalize pixel values to \[-1, 1]
|
| 75 |
+
* Data augmentation (flip, rotate)
|
| 76 |
+
|
| 77 |
+
2. **Training ESRGAN:**
|
| 78 |
+
|
| 79 |
+
* Generator: Residual-in-Residual Dense Blocks
|
| 80 |
+
* Discriminator: PatchGAN-based
|
| 81 |
+
* Losses: Content loss (VGG), adversarial loss, pixel-wise L1 loss
|
| 82 |
+
|
| 83 |
+
3. **Evaluation:**
|
| 84 |
+
|
| 85 |
+
* PSNR, SSIM
|
| 86 |
+
* Visual comparison with upsampled baseline (bicubic)
