Since the myth that all or nearly all political boundaries are defined
through coordinates is frequently brought up in OSM context a few
things to keep in mind:
There are three common types of boundary definitions:
* definition through point coordinates and geodetic lines between
* definition through physical geographical features like rivers or
ridges
* definition through a mathematical formular based on either coordinates
or physical features - this is primarily for maritime boundaries.
and a fourth (perhaps not true for international boundaries): town
boundaries in Massachusetts are primarily defined by granite markers.
A fifth: references to other borders
a) borders of larger entities
The town border continues until it hits the state border, then
turns and follows the state border...
b) borders of smaller entities
The town border goes along the border between Alice's land and
Bob's land...
See http://legislature.vermont.gov/statutes/section/24APPENDIX/003/00001
for an example of b) style.
