@tiffintech: Why does Google Maps never get you lost? OK maybe it does sometimes but this is pretty cool bow the tech works. Google Maps never gets you lost thanks to a complex system of technologies. It starts with a massive geospatial database, but static maps aren't enough. Therefore, it collects real-time data from millions of devices, feeding machine learning models for traffic prediction. But accurate navigation needs more than just predictions. Therefore, Google employs the A* search algorithm, an efficient pathfinding method that finds the optimal route by evaluating both the distance traveled and the estimated distance to the goal. This algorithm works on a graph of the road network, with edges weighted by current and predicted travel times. But even the best route is useless without knowing where you are. Therefore, Google fuses data from GPS, Wi-Fi, cellular networks, and device sensors for precise localization. Finally, map-matching algorithms ensure you always appear on the correct road. All this happens in milliseconds, leveraging Google's global network of data centers, to keep you on track no matter where you're headed. #Tech #technology #developer #stem #techexpert #techexplained
