Google Maps is the world’s most popular map. They have over a billion monthly users. Also, 5 million apps and websites use it weekly.
With Google Maps you get satellite images, street view, and real-time traffic data powered by billions of Android phones.
OpenStreetMap
OpenStreetMap (OSM) is a free mapping platform where users contribute and maintain map data. OSM is mostly supported by volunteers, so the data may not be as precise.
Compared to commercial maps, there are fewer available features. There’s no traffic data, business listings are not always up-to-date, and the routing is less robust compared to competitors.
