Dataset Structure

Images: RGB images captured across multiple variations:
- 8 different town layouts (7 urban + 1 rural)
- 5 weather/time conditions (ClearNoon, ClearSunset, ClearNight, CloudyNoon, MidRainyNoon)
- 12 viewpoint combinations (3 heights × 4 pitch angles)

Annotations

Each image comes with dense pixel-level annotations for:

Semantic segmentation (28 classes)
Instance segmentation
Depth information

Key Variations

Heights: 15m, 35m, 60m
Pitch Angles: 0°, 45°, 60°, 90°
Weather/Time: Various conditions to test robustness
Layouts: Different urban and rural environments

NOTE: This repo contains only a subset of the full dataset:

Heights & Pitch Angles:
- H_15_P_0 (15m height, 0° pitch)
- H_35_P_0 (35m height, 0° pitch)
- H_60_P_0 (60m height, 0° pitch)
Weather Condition: ClearNoon only
Town Layouts: Town01, Town02, Town05, Town07
Data Modalities:
- RGB Images
- Depth Maps
- Semantic Segmentation

Can effectively augment real-world training data to improve overall model performance

Model Evaluation and Testing

Diagnostic Testing

Serves as a test bed for assessing model sensitivity to various conditions including:
- Weather changes
- Time of day variations
- Different pitch angles
- Various altitudes
- Different layout types

Multi-modal Development

Enables development of multi-modal segmentation models by incorporating depth information alongside visual data
Supports testing how additional sensor modalities can improve aerial scene recognition capabilities

Research Applications

Enables studying synthetic-to-real domain adaptation for aerial imagery
Provides controlled variations for analyzing model behavior under different viewing conditions
Supports development of models for:
- Semantic segmentation
- Instance segmentation
