1. A method of identifying a location of interest between a user and an identified endpoint, comprising: computing a reference vector based on the user's current positional information, current velocity information, and the identified endpoint; designating, by a navigation unit, a sampling bandwidth based on current distance to the identified endpoint, wherein the navigation unit dynamically expands the sampling bandwidth as the user approaches within a predetermined distance of the identified endpoint; identifying one or more locations of interest within the sampling bandwidth that are between the user and the identified endpoint; computing a sampling vector for at least one of the one or more locations of interest within the sampling bandwidth; and alerting the user to the sampling vector for the at least one location of interest within the sampling bandwidth.
