US Patent 10083533 Geo-tagging digital images

Methods, systems, and apparatus, including computer programs encoded on computer storage media, are described for automatically and/or interactively editing image metadata. In one aspect, the methods include the actions of obtaining two from among three items of geo-metadata associated with an image. The three items of geo-metadata include an acquisition geo-location for the image, an acquisition geo-orientation for the image and a geo-location of a subject depicted in the image. The methods further include the actions of representing on a map the two obtained items of geo-metadata associated with the image, and determining candidates for the third item of geo-metadata based on the representations of the two obtained items of geo-metadata. In addition, the methods can also include the actions of determining the third item of geo-metadata associated with the image from among the generated candidates.
