Intro

Administrative Boundaries are defined as relations over ways that are either drawn for this purpose only, or use ways that naturally form the boundary, such as center lines of rivers.

Care must be taken not to join those river segments that are part of a boundary with other segments.

All county relations must be circular loops, i.e. all segments arranged in sequence, which can be checked in the JOSM relation editor.

The layers.openstreetmap.fr map viewer has some handy layers for checking the current state of our admin boundaries.


To Do:

Talk about Irish administrative districts: Provinces, Baronies, Civil Parishes, Townlands etc..

Baronies, Civil Parishes, Townlands details should be on each respective county page, eventually.
