25 million new buildings appeared on Google Maps

More precisely, not the buildings themselves, but their contours. Well, you understand what it is about. 25 million new buildings suggest that Google Maps, as a service, has become even more detailed and convenient. It is unlikely that any other similar service can be compared with Google Maps.

It should be noted that the new contours are mapped not by a person (so much work would drive any team of cartographers crazy), but by a computer, a system that analyzes aerial photography data, and renders rendered images of buildings and other objects on the map.

In creating this service you can help yourself using Google Map Maker. So, here you can indicate in which building which company works, plus to outline the outlines of the building on your own, if desired.

Now Google maps show us how difficult it is to build a detailed world map. For example, to add the outlines of buildings, you first need to get a shooting map, then you need to develop a technology to automate the addition of objects to the map (and such technologies do not always work correctly, for example, Apple demonstrated this in all its glory).

Well, the development team is already “finishing up” the work, polishing the results. So far, the result, namely Google Maps, meets the needs of many users, millions and millions. Let's see what will happen next.
