OUTDOOR TO INDOOR NAVIGATION SYSTEM

An outdoor-to-indoor (and vise versa) navigation system guides a traveler (30) to an interior point of interest (POI, 28) inside a three-dimensional structure (16) using a navigation device (10). When the traveler (30) reaches the destination (16) address, a 3D model of the destination object (16) is rendered on a display screen (12) and subsequent navigation assistance is rendered in relation to attributed features associated with the 3D model. Initial directional cues (33) associated with the 3D model guide the traveler (30) in relation to externally discernable POIs and toward an exterior portal POI (24). When the current position of the navigation device (10) generally coincides with the exterior portal POI (24), a set of final directional cues (35) are rendered which lead the traveler (30) in relation to internally discernable POIs to an interior feature POI (28). 3D navigation attributes may be associated with various POIs and used in the 3D portion of the navigation routing program.
