Overview
Map Memories turns travel photos into an interactive map-based journal. Photos are automatically geotagged using EXIF data, and trips can be replayed as animated routes on the map.
Key Features
- Automatic photo geotagging from EXIF metadata
- Interactive map with clustered photo markers
- Trip route visualization with animated playback
- Rich text notes attached to locations
- Offline map tile caching for travel use
Technical Highlights
EXIF data is extracted client-side using a lightweight parser that reads GPS coordinates, timestamps, and camera settings directly from image files. Photos without GPS data can be manually placed on the map.
Route playback animates a marker along the trip path using Mapbox's camera API, with smooth easing between stops. Photo clusters dynamically expand and collapse based on zoom level using a custom spatial index.
