A METHOD, SOFTWARE PRODUCT, DEVICE AND SYSTEM FOR DETERMINING A DIRECTION AT A POSITION

The present disclosure relates to a method for determining a direction at a position (211), the method (100) comprises obtaining (110) an orthorectified photo (210) of a region of Earth's surface comprising the position (211), and a coordinate system for the orthorectified photo (210); identifying (120) the position (211) in the orthorectified photo (210); identifying (130) a reference object (212) in the orthorectified photo (210); determining (140) a reference direction (215) between the position (211) and the identified reference object (212); capturing (150) at least one digital photo (220; 230) at the position (211) with a calibrated digital camera (331), wherein at least one of the at least one captured digital photo (220) depicts the reference object (222); and determining (190) the direction based on the at least one captured digital photo (220; 230) and the determined reference direction (215), wherein the determined direction is based on at least one pixel coordinate corresponding to the depicted reference object (222) in the at least one captured digital photo (220) depicting the reference object (222).
