Google Maps is one of the most influential applications in the world, developed by Google Inc. after being acquired from Where 2 Technologies in 2004. Initially coded in C++, it has evolved from a basic navigation tool to a comprehensive platform offering features like street view, ETA (Estimated Time of Arrival), and geocoding. The paper explores the algorithms and techniques used by Google Maps to provide accurate and real-time information. Google Maps uses graph data structures to calculate the shortest path between two points. Dijkstra's algorithm is employed to find the shortest path, but due to the large number of nodes and increased complexity, it is often replaced by the A* algorithm, which is more efficient. A* combines the actual cost to reach a node (g(x)) with an estimated cost to the goal (h(x)), making it faster and more effective in finding optimal paths. Street View is another key feature of Google Maps, providing 3D, panoramic images of locations. This feature involves capturing images using specially equipped vehicles and cameras, followed by complex image processing and stitching to create seamless panoramic views. Optical flow and other algorithms are used to align and warp images accurately. GPS and geocoding are essential for locating positions. GPS uses the GNSS network to determine latitude, longitude, and altitude. Trilateration is used to calculate the position based on signals from multiple satellites. The WAAS system enhances GPS accuracy by correcting signal errors. ETA calculation considers real-time traffic conditions, historical data, and average speeds to provide accurate travel time estimates. Google Maps uses a combination of data from various sources to predict travel times, taking into account factors like traffic, road types, and historical patterns. In conclusion, Google Maps employs advanced algorithms, techniques, and technologies to provide accurate and real-time information. It continuously updates and improves its features to enhance user experience, making it one of the most helpful and reliable applications.Google Maps is one of the most influential applications in the world, developed by Google Inc. after being acquired from Where 2 Technologies in 2004.
