Dear OSM Team,

I'm a java developer in a project which would help the disabled use public transportation with mobile device in Sydney, Australia. I thank you for the OSM data which is used for the project. The OTP(Open Trip Planner) is used to make a trip plan which shows the routing path including walking and transportation. The transportation routing could be drawn with transit information based on GTFS(General Transit Feed) format. However, the walking path is based on OSM data. The OTP engine provides the routing path with shortest algorithm and the OSM data. In Sydney metropolitan, the data is correct. Nevertheless, outer area of the metropolitan, such as Gosford, has some incorrect information as I check the data through JOSM tools. In the area, the walking path is drawn across a reserve without a road. We don't have enough resources. But we want to provide a correct routing information to the disabled. Do you have any idea to fix it easily ? In addition, can I ask how precise the OSM data is?

Thank you in advance.

The existing traces in the park I looked at seem to to align well with image so accuracy is within 4 metres I estimate. if you centre map over the area.zoom in and copy the link address from the permalink tab and paste in a comment some one may be able to do something to help.
