To make OpenStreetMap more navigable and accurate in guidance, our mapping team started an editing project in Europe. Munich is one of the cities on which we will focus. We will be editing and reviewing one-ways, turn restrictions, road geometry and correcting any errors that might show up during our analysis. We will follow the global OSM conventions alongside the ones specific for Germany, as they are described on these pages:Attributierung von Straßen in Deutschland, DE:Map_Features

The below analysis is based on Openstreetmap data downloaded on 17.03.2020.

Improve OSM


We will review and add if necessary the oneway=yes tag on navigable roads after consulting the available data (OSM Oneway key).

City Cases to Review
Munchen 110

Turn Restrictions

We will use the following tags:

-relations: type=restriction ; restriction= * ; except= *

-relations: type=restriction ; restriction:conditional= * ; except= *

-members: from, via, to

City Cases to review
Munchen 722

Road Geometry

We will add missing geometry to the existing navigable roads. Key:highway

Quality Assurance

Integrity checks

Potential errors generated by the Integrity Checks tool. They are to be reviewed and editen only if it is the case as they are not always errors.

Please check OSM Wiki Integrity checks page for more details on how the data was obtained.

Keep Right

Below is a statistic of potential errors generated by the Keep Right tool. These are to be reviewed and edited only if considered so since false-positive cases are also generated.

Please see Keep Right OSM Wiki page and for any additional information on the data below.
