+ 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:

+ ## πŸ“¦ 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.

14
+ ### πŸ›°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
+
23
+ ---
24
+
25
+ ### πŸ“ Directory Structure
26
+
27
+ The dataset is provided as two zip files:
28
+
29
+ ```
30
+ SAT_ELITE_DATA/
31
+ β”œβ”€β”€ train_set.zip # Paired training images
32
+ β”œβ”€β”€ val_set.zip # Paired validation images
33
+ ```
34
+
35
+ Each zip contains two folders:
36
+
37
+ ```
38
+ train_set/
39
+ β”œβ”€β”€ lr/ # Low-resolution Sentinel-2 images (input)
40
+ β”œβ”€β”€ 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.
46

48
+
49
+ ### πŸ“Š Image Specs
50
+
51
+ * **Format:** PNG (8-bit RGB)
52
+ * **Patch Size (HR):** 256Γ—256
53
+ * **Patch Size (LR):** 32Γ—32
54
+ * **Normalization:** No pre-applied normalization β€” users can apply their own preprocessing (e.g., mean/std normalization, scaling to \[-1, 1]).
55
+
56

57
+
58
+ ### 🎯 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
+
67
+ ---
68
+
69
+ ### πŸ”§ 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)
