+# 🛰️ Solar Plants Brazil
+
+**Solar Plants Brazil** is a geospatial dataset for **binary semantic segmentation** of photovoltaic (PV) solar power stations in satellite imagery. It consists of multi-spectral image tiles (including near-infrared) with pixel-level annotations indicating the presence of solar panels. This dataset enables training and evaluating deep learning models that automatically detect solar farm installations from overhead imagery, supporting applications in renewable energy mapping and remote sensing.

+
+## Dataset Overview
+
+- **Purpose**: Identify photovoltaic solar plant locations via binary segmentation (panel vs. background) in satellite images  
+- **Imagery**: 4-band (RGB + Near-Infrared) GeoTIFF tiles at 256×256 pixels each (float32 pixel values)  
+- **Labels**: Corresponding binary mask for each image (1 = solar panel, 0 = no panel)  
+- **Volume**: 272 image/mask pairs in total, split into training, validation, and test sets (201 train, 35 val, 36 test)  
+- **Geography**: Tiles are from various locations across Brazil, focusing on known solar farm sites  
+- **Metadata**: GeoTIFF files include spatial reference (CRS) and geolocation

+├── train/
+│   ├── input/       # 256x256 RGBNIR images (GeoTIFF)
+│   └── labels/      # 256x256 binary masks (GeoTIFF)

+```
+
+Each image is named `img(<ID>).tif` with its corresponding mask `target(<ID>).tif`. All images are pre-cropped to 256×256 pixels. The masks are binary, with `1` representing solar panels.

+
+## 🔧 TorchGeo Integration
+
+This dataset is integrated with the [TorchGeo](https://github.com/microsoft/torchgeo) library and can be loaded as:
+
+```python
+from torchgeo.datasets import SolarPlantsBrazil
+
+dataset = SolarPlantsBrazil(split="train", root="data/", download=True)
+sample = dataset[0]
+image_tensor, mask_tensor = sample["image"], sample["mask"]
+print(image_tensor.shape, mask_tensor.shape)
+```
+
+This returns image tensors with 4 channels and single-channel binary masks.
