12/24/2014

This article delves into the process behind creating accurate maps for Google Maps. It explains how Google combines data from satellite imagery, Street View cars, and user contributions to gather information about roads, landmarks, and points of interest. The article highlights the importance of 'Ground Truth,' which involves manually verifying and correcting map data. Google employs a large team of 'Google Mappers' who meticulously review and update map information to ensure accuracy. The article also touches upon the challenges of mapping remote areas and the continuous efforts to improve Google Maps through collaboration with users and the integration of new technologies.
