Geofencing & Geolocation — Locate. Detect. Automate.
Master browser location APIs and zone-based logic with topic-wise assignments. Each track includes 20 Basic, 20 Intermediate, and 10 Advanced questions so learners can progress from raw coordinates to production-ready geofence engines.
Why practice with these assignments?
- Move beyond theory—read live location, draw maps, and detect transitions.
- Internalize accuracy, permissions, caching, and battery-friendly polling.
- Build Entry/Stay/Exit workflows used in logistics, attendance, safety, and retail.
- Prepare for interviews with tasks that mirror real products.
How it works
- Pick a track (Geolocation or Geofencing).
- Attempt questions in order: Basic → Intermediate → Advanced.
- Test on real devices and desktop simulators; verify with logs and on-map visuals.
- Handle error codes and edge cases (timeouts, high-accuracy trade-offs).
- Save your best solutions as portfolio demos.
What you’ll achieve
- Confident use of getCurrentPosition / watchPosition and robust error handling.
- Reliable inside/outside detection (circles & polygons) with Entry/Stay/Exit sequencing.
- Practical skills with Haversine distance, local storage logs, and map overlays.
- Production habits: rate limiting, accuracy thresholds, retries, and audit logs.
Who should use this page?
Beginners learning location APIs, students preparing for interviews, and developers building logistics, delivery, attendance, or safety features.
Tips for success
- Tune accuracy: high accuracy costs battery—use only when needed.
- Choose sensible polling: event-driven watchPosition for movement; interval checks for audits.

FAQs
Q1. Do I need Google Maps for these assignments?
Not strictly. You can complete core logic without a map. However, maps are useful for visualizing and debugging geofences.
Q2. How do I verify correctness?
Log coordinates, render markers or zones, and record transitions with timestamps. Assert expected sequences like Entry → Stay → Exit.
Q3. Is server code required?
Only for API or webhook-based tasks. You can mock endpoints during practice to simulate responses.
Q4. What devices should I test on?
Test on desktop and at least one mobile phone. Compare high-accuracy GPS vs cached results and observe battery consumption.
Q5. How much time should I spend per assignment?
Plan 30–60 minutes per difficulty band per topic. Multi-user simulations and full dashboards may take longer.
Q6. Do I need internet access for all tasks?
Not always. Some tasks can use simulated GPS coordinates offline. Real-world tracking and API calls require internet access.
Q7. What topics are covered in these assignments?
Assignments include GPS basics, geofencing zones, entry/exit detection, push notifications, API integration, multi-user tracking, and performance testing.
Q8. Do I need mobile app development knowledge?
Basic web-based geolocation APIs are enough for most tasks. Some advanced tracks may include mobile frameworks like React Native or Flutter.
Q9. Can I test these assignments indoors?
Yes, but accuracy will vary. Use simulated coordinates or mock location tools for consistency when testing indoors.
Q10. Can these assignments help in projects or jobs?
Definitely. Location-based apps are widely used in logistics, delivery, fitness, and smart security. These assignments prepare you for real-world applications.
