Activity Map

Activity Map –

you’re describing is essentially a real-time, location-based visualization system. Here’s a breakdown of what this feature entails, along with technical considerations and possible implementation details:

Feature Overview: Activity Map –

 Purpose:

Visualize a live feed of posts on a geographical map interface, where:

  • New posts appear instantly as they are created.
  • Older posts gradually fade out or disappear after a custom user-defined duration.

Key Functional Components:

  1. Real-Time Post Ingestion:
    • Use technologies like Web Sockets, Firebase Realtime Database, or Socket.io to stream new posts in real-time.
  2. Geolocation Tagging:
    • Each post should have associated latitude and longitude coordinates.
    • Optional: Use IP-based geolocation or user device GPS data.
  3. Map Visualization:
    • Use libraries like:
      • Mapbox GL JS
      • Google Maps JavaScript API
      • Leaflet.js (open-source)
    • Overlay posts as custom markers, heat points, or animated pins.
  4. Post Fading Logic:
    • Each post has a timestamp.
    • Posts automatically fade out or are removed based on a time-to-live (TTL) value defined by the user (e.g., last 5 minutes).
    • Fading effect via CSS transitions or canvas rendering (for smoother animation).
  5. User-Defined Time Filter:
    • UI component (slider, dropdown, or input box) to let the user set how long a post remains visible on the map.
  6. Optional Enhancements:
    • Filters by post type, category, or hashtag.
    • Clustering for high-density areas.
    • Playback mode to view historical data over time.
    • Color-coding for post sentiment or content type.

 UI/UX Example:

A user sees a world map with markers appearing in real-time:

  •  New marker appears in NYC — fades in.
  •  After 3 minutes, it starts fading out.
  •  After 5 minutes, it’s completely removed.

Users can adjust the “fade-out after” setting from a control panel.
