Routeing Guide Easements
An easement which extends permission is a positive easement. An easement which narrows permission is a negative easement. Map, double-back and fare route easements are always positive. Circuitous route easements are always negative. Other kinds of easements can be positive or negative. A journey which follows a route otherwise permitted by the Routeing Guide may be forbidden by a negative easement.
