468:, but a representative point of the feature near its middle. If this should fall in a non-representative portion, the coordinate point chosen should be moved further toward one end. If the midpoint of a highway falls at an intersection with another highway, the coordinate chosen should be moved some distance from the intersection so that the other highway is not misinterpreted as the feature. Likewise, a highway portion which splits into two streets (as in an urban one way grid) should not be used as the selected point unless that
154:
Flexibility is needed in order to label a representative point. For example, a canal's "main" coordinates may be best given as a point where it is a body of water; a nearby location may be better than a midpoint occupied by a notable or atypical object such as a tunnel or causeway.
147:
In any of the above cases, which involve more than one pair of coordinates, a single (or "main") pair may be used as the coordinates for the whole article (and for its inclusion in partner sites such as Google Maps).
481:
Coordinates for points on linear features should use a high level of precision, commensurate with features' small width, not great length, to ensure that the points are centred on, not merely near, the feature.
68:
The best method may depend on the type of feature, its length, and the number of significant points of interest along it (though such points need not be sufficiently notable as to warrant their own article).
461:
Route is a series of paths, as in a highway route. Or a long distance hiking trail, a series of individual trails which (usually) connect. To be unambiguous, the point must not be near any intersection

A "main" coordinate may not be appropriate for very long features; the definition of "very long" in this context is yet to be determined.
