Abstract

Using geographical coordinates and geographical information described by map data, a determination (202) is made of map geographical features that are within the line of sight of the geographical coordinate. The determined map geographical features are represented (203) with a respective map value. A digital image is obtained (204), the image being recorded at a first geographical position of a landscape visible at the first geographical position. Image geographical features are identified (205) in the digital image and a query data structure is created (206). The query data structure comprises image values that represent the identified image geographical features in the digital image. A matching is then performed (207) of the query data structure with the map values representing the map geographical features. An estimate is thereby obtained of a geographical coordinate for the first geographical position at which the digital image was recorded.
