# 🏘️ Drone Building Extraction Dataset — Calgary

A high-resolution drone imagery dataset for binary building segmentation,
captured over a residential area in **Calgary, Alberta, Canada**.
Designed to work directly with [GeoSeg Studio](https://github.com/dronnix-io/GeoSegStudio)
— an open-source QGIS plugin for deep learning semantic segmentation.

├── train_raster.tif ← 4-band GeoTIFF orthomosaic (larger area)

## 🔍 About the Data

- **Rasters:** High-resolution 4-band (RGB + Alpha) orthomosaics produced
from drone imagery using DJI Terra software. The alpha channel marks
areas with no image coverage (no-data mask). Provided as full-area
GeoTIFFs — tiling is handled by GeoSeg Studio's Prepare tab.
- **Vectors:** Building footprint polygons manually digitized in QGIS by
the Dronnix team. Stored as GeoJSON in EPSG:32611.
- **Labels:** Binary — building (foreground) vs. background.
- **Train area:** Larger residential neighborhood in Calgary
- **Test area:** Smaller adjacent region for independent evaluation

## 🚀 How to Use

This dataset is designed for use with **GeoSeg Studio**:

1. Install [GeoSeg Studio](https://github.com/dronnix-io/GeoSegStudio) QGIS plugin
2. In the **Prepare** tab, load `train_raster.tif` as the raster layer and `train_vector.geojson` as the vector layer
3. Set tile size, stride, and output directory
4. Run **Apply Clipping** → **Apply Splitting** → **Apply Augmentation**
5. Train your model in the **Train** tab
6. Evaluate on the test set using `test_raster.tif` and `test_vector.geojson`
