Most of the counties in Ohio are missing the townships. I'd like to begin by adding the townships that exist in my county, and I've been reading everything I can find about relations, boundaries, etc. (I'm a newbie). It would be really helpful to have a good example where this is done correctly so that I can examine how the shared boundaries are tagged...and any other info that would help would be greatly appreciated! |

According to http://wiki.openstreetmap.org/wiki/Admin_level#10_admin_level_values_for_specific_countries, townships should be admin_level=7 in most of the US. I would highly recommend using type=boundary, boundary=administrative relations for these. Then those boundary ways can be reused for multiple townships/cities/counties/etc. Here's an example of a township done with relation: http://www.openstreetmap.org/relation/2342528 |

Have a look at Ireland. In Ireland, we're adding |

I've been doing the same in Pennsylvania and have Clarion, Butler, Armstrong, and Greene Counties completed. You can take a look at some of my more recent edits to see how I've done these township relationships. The only difference you would have is admin_level... PA has incorporated townships, so their level is 8, while OH would use level 7. |
