More recently, namely until may 2011, "Yandex" in the preparation and updating of their cards have used the services of a third-party specialist company "Geocenter-Consulting".

The list of organizations with which cooperation was entered with the above mentioned company "Geocenter-Consulting".
The update begins with a detailed analysis of vector and satellite maps, systematically executed pictures of various areas. As the data sources use the address database, in which constructed objects are added, their addresses and geographic coordinates. Actively tracked information from open sources – the official websites of cities and developers, the maps competitor Google. If necessary, the surveyors go out to the field personally.
The company "Yandex" understands that people living in the area, it is better to notice all the inaccuracies and errors in the compiled maps. Therefore launched the "people's map". With it, users of "Yandex" can take an active part in recruitment and updating of maps. For this via the feedback form you can send your amendment. Information will be checked by specialists and taken into account when preparing updates.
After all changes are made, they are coordinated with other objects in the card, verifies the additional information.
