Currently, the Yandex search engine has the most detailed electronic maps of Russia and other countries. But there is no limit to perfection - regularly, several times a month, the company updates its maps, adding new changes to them, clarifying details and eliminating white spots. It becomes interesting how this all happens.

Not so long ago, namely until May 2011, Yandex used the services of a third-party specialized firm Geocenter-Consulting when drawing up and correcting its maps. However, over time, third-party services began to lead to unreasonable costs, and the efficiency of updating information began to lag behind the main competitor - Google. Therefore, since May 2011, Yandex abandoned this practice and decided to create its own cartographic service.

In order not to start creating a complex organization from scratch, Yandex acquired a reputable company, GIS Technologies, which is engaged in mapping and has a state license for this. This organization is engaged in the coordination of existing information with the Office of Geodesy and Cartography of the Russian Federation and its regional branches, exchanges updates with other interested participants - Roskartografiya, TGA CJSC, Resident CJSC, aerogeodetic enterprises. The list of organizations with which cooperation has been established includes the aforementioned company "Geocenter-Consulting".

The update begins with a detailed analysis of vector and satellite maps; images of various territories are systematically taken. Address databases are used as data sources, to which constructed objects, their addresses and geographic coordinates are added. Information from open sources is actively monitored - the official websites of cities and developers, on the maps of the competitor Google. If necessary, cartographers visit the site in person.

Yandex understands that people living in a given area are better at noticing all the inaccuracies and errors in the compiled maps. Therefore, we launched the People's Card service. Using it, Yandex users can take an active part in replenishing and updating maps. To do this, you can send your amendment through the feedback form. The information will be checked by the company's specialists and taken into account when preparing updates.

After all changes are made, they are coordinated with other map objects, additional information is verified. The completely updated version is certified by the Central Cartographic and Geodetic Fund, and then by the Federal Service for State Registration, Cadastre and Cartography. These organizations issue permission to publish a new Yandex map.
