track's end and the other track's beginning is less than the speciﬁed number of minutes.

The default value is 30 minutes.

Matching limit: HoudahGeo determines the location where a photo was taken by

matching it up with two track points: one preceding and one following the time the photo

was taken. If the closest point's timestamp is more than the speciﬁed number of minutes

before or after the photo was taken, HoudahGeo considers there is no match and does

not geocode the photo. The default value of 0 disables this check.

Waypoint geocoding: Enable automatic geocoding from GPS waypoints. This applies

to images for which track log geocoding yielded no result. For each image HoudahGeo

will try to locate a waypoint that is close in time and match the image to that waypoint’s

location.

4.2.5. Geocode from Reference Photos

You may already have a camera that takes geotagged photos. Actually many camera

phones take geotagged photos. With HoudahGeo you may use these photos as

references to tag photos taken with another camera during the same time frame.

At each location you would take one geotagged picture as well as a series of regular

photos. Then you load photos from both cameras into a HoudahGeo project. The

Geocode from Reference Photos feature can then copy coordinates from the

reference photos to other photos taken within the same time frame.
