| ## 📦 SAT\_ELITE\_DATA |
|
|
| **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. |
|

|
| ### 🛰️ Dataset Overview |
|
|
| | Domain | Source | Spatial Resolution | Description | |
| | -------- | ---------- | ------------------ | -------------------------------------------- | |
| | Low-Res | Sentinel-2 | 10 meters/pixel | Multispectral satellite imagery (RGB subset) | |
| | High-Res | NAIP | 1 meter/pixel | Aerial imagery from USDA's NAIP program | |
|
|
| 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). |
|

|
| ### 📁 Directory Structure |
|
|
| The dataset is provided as two zip files: |
|
|
| ``` |
| SAT_ELITE_DATA/ |
| ├── train_set.zip # Paired training images |
| ├── val_set.zip # Paired validation images |
| ``` |
|
|
| Each zip contains two folders: |
|
|
| ``` |
| train_set/ |
| ├── lr/ # Low-resolution Sentinel-2 images (input) |
| ├── hr/ # High-resolution NAIP images (target) |
| ``` |
|
|
| The same structure applies to `val_set/`. |
|
|
| 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. |

| ### 📊 Image Specs |
|
|
| * **Format:** PNG (8-bit RGB) |
| * **Patch Size (HR):** 256×256 |
| * **Patch Size (LR):** 32×32 |
| * **Normalization:** No pre-applied normalization — users can apply their own preprocessing (e.g., mean/std normalization, scaling to \[-1, 1]). |
|

|
|
| ### 🎯 Use Case |
|
|
| This dataset is designed for: |
|
|
| * Super-resolution model training (e.g., **ESRGAN**, **EDSR**, **SRGAN**) |
| * Remote sensing image enhancement |
| * Satellite-to-aerial domain transfer learning |
| * Visual fidelity and detail recovery in earth observation pipelines |
|
|

|
|
| ### 🔧 Suggested Training Pipeline (ESRGAN) |
|
|
| 1. **Preprocessing:** |
|
|
| * Resize Sentinel-2 images to match HR resolution using bicubic interpolation (if needed) |
| * Normalize pixel values to \[-1, 1] |
| * Data augmentation (flip, rotate) |
|
|
| 2. **Training ESRGAN:** |
|
|
| * Generator: Residual-in-Residual Dense Blocks |
| * Discriminator: PatchGAN-based |
| * Losses: Content loss (VGG), adversarial loss, pixel-wise L1 loss |
|
|
| 3. **Evaluation:** |
|
|
| * PSNR, SSIM |
| * Visual comparison with upsampled baseline (bicubic) |
