Stream Real-Time Geo

About this course

Stream Real-Time Geo is a beginner-level course that introduces how real-time geographic data pipelines work in applications such as fleet tracking, logistics dashboards, and IoT monitoring systems. The course is designed for learners with basic JavaScript skills and familiarity with web maps and geographic coordinates who want to understand how live GPS data moves from devices to interactive dashboards. You will begin by ingesting simulated GPS messages using MQTT, a lightweight messaging protocol commonly used in IoT systems. You will observe how location events are structured, transmitted, and received in a publish–subscribe pipeline. Next, you will visualize streaming GPS tracks using Leaflet, an open-source JavaScript mapping library. You will build a live map that updates as new coordinates arrive, learning how markers, paths, and map interactions translate raw location data into operational insight. Finally, you will measure end-to-end latency across the pipeline to understand where delays occur between devices, brokers, and the map visualization. By the end of the course, you will be able to ingest GPS streams, display them on an interactive map, and analyze latency to improve real-time geospatial applications.

Course objectives

• understand the structure and transmission of location data
• build a live map that updates with new GPS coordinates
• measure and analyze end-to-end latency in data processing
