So i did quite a big trip recently, and took lots of pictures with my DSLR and occasionally Android phone. Only after coming back did i read about the whole GPX file, tracklog options in Lightroom. meaning i don't have such a tracklog file.

The android phone did geotag most photos it took. (at least, when it got a gps fix i guess)

So my question is, is there some software or way that will automatically copy the geotag from the android's photos to photos taken on the same time with my DSLR?

Or alternatively, generate a tracklog from the geotagged data in the android pictures?

  1. It seems that there is no way to create a tracklog from within Lightroom. I just did a Google search on that and looked in Lightroom 4 for options.

  2. You can create a tracklog from your geotagged pictures using exiftools.

    Save the following print configuration to a file named gpx.fmt in your working directory.

    #------------------------------------------------------------------------------
    # File:         gpx.fmt
    #
    # Description:  Example ExifTool print format file for generating GPX track log
    #
    # Usage:        exiftool -p gpx.fmt FILE [...] > out.gpx
    #
    # Requires:     ExifTool version 10.49 or later
    #
    # Revisions:    2010/02/05 - P. Harvey created
    #               2018/01/03 - PH Added IF to be sure position exists
    #               2018/01/06 - PH Use DateFmt function instead of -d option
    #
    # Notes:     1) Input files must contain GPSLatitude and GPSLongitude.
    #            2) Add the -ee option to extract the full track from video files.
    #            3) The -fileOrder option may be used to control the order of the
    #               generated track points when processing multiple files.

    Run the following command. It will read all the geo information out of the exif data from the android pictures and create a XML document formatted in the GPX way.

    exiftool -fileOrder gpsdatetime -p gpx.fmt -ext jpg . > out.gpx

You can use an Eyefi sd card in your camera so as the card sends the files to your android device, the Eyefi app will add the GPS info to the EXIF data. Totally automated.

  • exiftool can be used to create a gpx file, as Unapiedra describes. In some Linux distributions, the gpx.fmt is already installed. After the gpx file has been created, exiftool can be called again to tag untagged files. Change filenames and time-zones as appropriate.

    exiftool -fileOrder gpsdatetime -p /usr/share/doc/libimage-exiftool-perl/fmt_files/gpx.fmt -ext jpg . > out.gpx
    
    exiftool -if 'not ($GPSLatitude or $GPSLongitude)' -geotag out.gpx '-geotime<${createdate}-00:00' -r -ext jpg  .
  • If you have Google Location History turned on, you can download KML files from Google Timeline or Takeout. Then use exiftool to tag your photos.

    exiftool -if 'not ($GPSLatitude or $GPSLongitude)' -geotag history.kml '-geotime<${createdate}-00:00' -r -ext jpg  .

While it isn't an automated solution, if you manually select the group of photos that you took at the same location as one from Android, you can Ctrl-click (or Command-click for Mac) on the location on the map that the Android photo is at and it will place them with it and update the Geotagging.
