Abstract

A method for determining a direction at a position is provided. The method involves obtaining an orthorectified photo of a region of Earth's surface comprising the position, and a coordinate system for the orthorectified photo; identifying the position in the orthorectified photo; identifying a reference object in the orthorectified photo; determining a reference direction between the position and the identified reference object; capturing at least one digital photo at the position with a calibrated digital camera, wherein at least one of the at least one captured digital photo depicts the reference object; and determining the direction based on the at least one captured digital photo and the determined reference direction, wherein the determined direction is based on at least one pixel coordinate corresponding to the depicted reference object in the at least one captured digital photo depicting the reference object.
