algorithm and to start automatic geocoding over.

Selected images only: Kickstart automatic geocoding only for the currently selected

images. Settings made below nonetheless apply to the whole project.

Track log geocoding: Enable automatic geocoding from GPS track logs. HoudahGeo

a given photo. A photo is considered to match up with a track if it falls within the track's

time span or within the speciﬁed number of minutes before the beginning or after the

end of that time span. The default value is 5 minutes.

signal. Strictly speaking we cannot geocode a photo that falls between two tracks.
