This tutorial series explores the integration of the Google Maps JavaScript API and PubNub to create live, real-time web applications with geolocation features, focusing on the development of flight paths using dynamic polylines. It guides users through setting up a JavaScript environment, implementing map markers, and utilizing the HTML5 Geolocation API to track movement patterns in real time. The series concludes by demonstrating how to initialize PubNub for real-time data streaming across various platforms and how to publish new latitude and longitude positions using JavaScript. The tutorial emphasizes the synergy between Google Maps API and PubNub for applications requiring real-time location tracking, similar to ride-hailing services like Uber and Lyft. Additionally, it provides resources such as demos, GitHub code repositories, and PubNub documentation for further exploration and application development.
