Design a Global Map and Navigation System

Google Maps System Design

Design a global-scale mapping and navigation system similar to Google Maps. The system must handle rendering interactive maps, searching for millions of points of interest (POIs), and providing real-time turn-by-turn navigation with live traffic updates. Focus on geospatial indexing strategies, efficient pathfinding algorithms for millions of concurrent users, and the data pipeline required to ingest and process crowd-sourced traffic data at scale while maintaining low latency and high availability.

Design Google Maps

Design a comprehensive geospatial system similar to Google Maps that supports global map rendering, high-concurrency point-of-interest (POI) search, and real-time navigation. The system must handle 100M+ daily active users, provide sub-second routing responses, and incorporate real-time traffic data to adjust ETAs. Address specific challenges regarding geospatial indexing, massive data ingestion for location pings, and efficient distribution of map assets at scale.

Design a Global Map and Navigation System

Design a comprehensive mapping system similar to Google Maps that supports real-time rendering, location search, and navigation. The system must handle over 1 billion daily active users, provide low-latency map tile delivery (under 50ms), and offer accurate turn-by-turn driving directions adjusted for real-time traffic conditions. Address how you would efficiently store and query hundreds of millions of points of interest (POIs) and how you would scale the routing engine to handle global road networks while maintaining high availability and consistency for road data updates.
