Galarina recently released v3.2 of GeoLogTag, an iOS app that
uses your iPhone’s GPS functionality to automatically geotag photos (embed
location information into the photo’s metadata) from nearly any digital camera.
To geotag photos using GeoLogTag you first synchronize the
app’s clock with your digital camera’s internal clock. Running on your iPhone (it can run in the background, with certain limitations),
GeoLogTag keeps a log of your locations as you shoot. It can keep a continuous
log, or mark your location at specific intervals such as once every three or
five minutes. Later, the time code on the log created by GeoLogTag is compared
to the capture time of downloaded photos on your computer and location data is
embedded in the metadata of the photos.
On Macs (which OS versions are supported is not specified)
with file sharing turned on, this can be done automatically over WiFi by the
app itself, which searches a shared folder for geotaggable photos. It can embed
geotags in JPEG images from almost any digital camera and raw files from a wide
range of DSLR cameras from Canon, Nikon, and most other manufacturers.
On Windows PCs, you export a geolog (GPX) file, which is
then used by a separate geotagging application such as RoboGeo or Geosetter to
embed geotags into your downloaded images.
The update to v3.2 adds the ability to automatically geotag photos stored on
SmugMug (Flickr support was already included in previous versions.) The
GeoLogTag app costs US$4.99 and is available from the iPhone App Store.
