City-wide navigation
For city-wide navigation, we use datasets available from OSM.
For place search, we use an OSM database, retrieved from https://www.geofabrik.de/ . We host the dataset on our servers.
In order to make changes in the dataset, you can follow these instructions: https://blog.locationiq.com/how-to-add-an-address-to-openstreetmap-a-3-step-guide/
