AR Geography App with 3D Map Overlays – IT & Computer Engineering Guide
1. Project Overview
The AR Geography App with 3D Map Overlays is an educational augmented reality application designed to enhance geography learning by projecting interactive 3D maps, terrains, landmarks, and natural features onto real-world surfaces. The app provides students with an immersive experience that bridges the gap between textbook learning and spatial understanding of geographical concepts.
2. System Architecture Overview
- AR Rendering Engine: Displays and manipulates 3D
geographical models
- Map Data Integration: Fetches real-time or preloaded geographical data
- User Interaction Layer: Allows touch, gesture, or gaze-based interaction
- Backend Services: Stores user progress, preferences, and downloadable content
- Content Management: Teachers or admins can update or customize overlays
