How can a project like this create accurate maps?

● By the very nature of the wiki-style process there is no guarantee of accuracy of any kind.

● Then again, few proprietary maps carry a guarantee of accuracy, either.

● In fact, some have artificially-introduced errors.

Mapping

● This is not just an online project.

● We are getting out from behind our computer screens, and surveying towns and countryside to create our maps.

● This is very much a community mapping effort.

● We use wiki-style collaborative editing software to support this, ...

Beginners' guide

● You need a computer connected to the Internet and some time to gather information and then enter it.

● Given the excellent aerial photography available in the editors these days, a GPS is less important than in the early days of the project.
