There is just this problem with OSM ... 31

Slide 32

Slide 32 text

When proposing OSM to a customer or use it in a service, we take on responsibility for the data. 32

Slide 33

Slide 33 text

Major OSM issues (in Japan) 33 ● Large spread of data coverage and quality. ● Insufficient address/POI data ● Vertical and dense urban areas ● Use of data beyond rendering map images Responsibility for map data bears an additional risk.
