LandSnap is a Django-based web application designed to analyze land changes over time using comparative image analysis. It leverages advanced computer vision algorithms to detect and visualize differences between two aerial images of the same location taken at different times.
- Image Upload: Upload two images of the same location for analysis.
- Change Detection: Identify changes in terrain, vegetation, and structures.
- Heatmap Visualization: View detailed analysis results with heatmap overlays.
- Responsive Design: User-friendly interface optimized for various devices.
