Geotagging: Auto Mode

PhotoLinker's automatic geotagging mode is the simplest method for quickly geotagging hundreds of photos by utilizing the track log from a GPS receiver.

Loading Tracks

To use Auto Mode you can load your photos and track files by dragging them into PhotoLinker and dropping them onto the map or image browser. Tracks may need to be downloaded directly from some GPS receivers.

• Downloading from the GPS

Using Auto Mode

• Open the Geotagging Console and make sure that Auto is selected.
• Set the time zone and/or shift the time on your photos.
• Editing the geotagging criteria.
• When you are satisfied with the proposed locations, click the Geotag Photos button.

Time zone

Your GPS records dates and times with time zone information; your camera, however, does not. When you first open the geotagging console you are asked to enter the time zone used by your camera. If you need to shift the date and time on your photos, you can click the *Date & Time Shifter button. The proposed location flags will instantly update as you change the time zone or shift the time on the photos.

Information Bubbles

If you hover your mouse over one of the proposed locations, PhotoLinker will show an information bubble about that geotagging point.

Unable To Geotag Message

In some cases a message will be reported in the geotagging console that one or more photos cannot be geotagged. There are a number of reasons this may occur, including the photo failing the distance or time criteria. In many cases the is a result of an incorrect time zone setting.

Edit Criteria

• The first option allows you to place a restriction on the temporal distance between the nearest track point and the time the photo was taken (default: 300 seconds/5 minutes) from nearest track point).
• The second option allows you to place a restriction on the physical distance between the two track points surrounding the time the photo was taken.
• Selecting AND requires both critieria to be met before linking will occur. Selecting OR will link if one of the two criteria are met.
• If no time or distance criteria are selected, linking will occur to the nearest recorded point or time-weighted average (as selected) without restriction.
• You can choose to link the nearest recorded point in time, or the time weighted average point (if one exists, otherwise the photo will be ignored).

Additional Options

• The Zoom All will zoom the map to show all proposed locations.
• The Rotate Flags button will rotate the flags 90 degrees for cases where it may be easier to see.
