Yandex.Maps is a search and information service that you can use to:

Mobile Yandex.Maps

Mobile Yandex.Maps helps you quickly navigate an area and plan your trip by car or on public transport.

Once you install Mobile Yandex.Maps, you can also contribute information about road congestion to Yandex.Traffic (which gets its information about traffic speed not only from partner companies, but also from Mobile Yandex.Maps users). In this process, all data is obfuscated so that it doesn't contain any information about the user or their car.

Yandex.Maps API

The Yandex.Maps API is a service you can use to install Yandex.Maps on your site. The API gives you access to the entire contents of Yandex.Maps, including hundreds of detailed city maps, satellite images, and data from the Yandex Business Directory. It also lets you search by business or organization.

The Yandex.Maps API allows you to create an interactive map, display your data on it, and implement geolocation services of varying degrees of complexity.
