Lesson 4 • Cell Network Positioning Methods

Covers Cell-ID, timing advance, and observed time difference techniques. Connects each method to accuracy expectations and network dependency.

Lesson 1 • Mobile Location Services on iOS and Android

Surveys platform location managers, permission tiers, and background modes. Students configure location updates for both foreground and background use.

Lesson 2 • Routing and Directions API Integration

Covers route request parameters, travel modes, waypoints, and response parsing. Students build a turn-by-turn directions feature in a sample app.

Lesson 3 • Geocoding and Reverse Geocoding APIs

Explains forward and reverse geocoding, structured vs. unstructured queries, and result ranking. Students convert addresses to coordinates and back.

Introduces raster and vector tile services, map SDK initialisation, and layer management. Students render a custom map with location markers.

Lesson 1 • Core Spatial Operations

Teaches buffering, intersection, union, and point-in-polygon operations. Students apply these operations to solve real-world proximity problems.

Lesson 2 • Geospatial Reporting and Dashboard Design

Guides students through dashboard layout, KPI selection, and map-chart integration. Students deliver an interactive geospatial report for a business scenario.

Lesson 3 • Spatial Data Structures and Indexing

Covers R-trees, geohash, and H3 indexing for efficient spatial queries. Students choose the right index for a given query pattern and dataset size.

Lesson 4 • Trajectory and Movement Analysis

Covers GPS track cleaning, segmentation, and movement metrics. Students extract speed, dwell time, and route patterns from raw trajectory data.

Lesson 1 • Scaling Geofence Systems

Addresses indexing strategies, event queuing, and multi-tenant fence management. Students design a geofence backend capable of handling millions of devices.

Lesson 2 • Entry, Exit, and Dwell Event Detection

Covers event-detection algorithms, debounce logic, and dwell thresholds. Students implement entry/exit detection that minimises false positives.

Lesson 3 • Server-Side vs. Device-Side Geofencing

Compares on-device and server-side evaluation for latency, battery, and scale. Students choose the right architecture for a given deployment scenario.

Lesson 4 • Geofence Use Cases and Integration Patterns

Surveys fleet management, retail, and safety applications of geofencing. Students map business requirements to geofence trigger and notification designs.

Lesson 1 • Anonymization and De-identification Techniques

Explains spatial generalisation, k-anonymity, and differential privacy for location data. Students apply anonymisation to a sample trajectory dataset.

Lesson 2 • Location Data Privacy Principles

Covers data minimisation, purpose limitation, and consent requirements for location data. Students apply privacy-by-design principles to a location feature.

Lesson 3 • Regulatory Frameworks for Location Data

Surveys global privacy regulations and their location-specific provisions. Students identify compliance obligations for a cross-border location service.

Lesson 4 • Building a Privacy-Compliant Location Feature

Guides students through consent UI, data retention policies, and audit logging. Students produce a compliance checklist for a production location feature.

Lesson 1 • High-Availability and Fault-Tolerant Design

Covers redundancy, failover, and graceful degradation for location services. Students apply resilience patterns to a reference architecture diagram.

Lesson 2 • Performance Optimization and Cost Management

Addresses update-rate tuning, data compression, and API cost reduction strategies. Students produce an optimisation plan for a high-volume location service.

Lesson 3 • Machine Learning for Location Prediction

Introduces next-location prediction, anomaly detection, and place classification models. Students train and evaluate a simple location prediction model.
