[OSM-dev] Call to mobile developers: OSM binary file format

[Roberto Navoni]

Hi Marcus,
normaly the company as Teleatlas or Navtech  sell their data in some 
public format as shape or GDF , then the data is organized in different 
way , but is not binary data. Is not possible to share this kind of 
technical information because We sign a NDA. But if you have some 
question about the Navigation System  architecture i can reply to you ;)
