How to add GPS data to a JPEG file (Exif)

Hi,
I am trying to do geotag my pictures. The problem is that all the
solutions have too much of GUI and thereby slow for my needs. I have
tried using Picasa/Google Earth and WWMX location stamper, both of
which are slow for my purposes. I have also tried checking exiftool,
which doesn't really give out a good example for me.

1. I want to do a command line operation to add latitude/longitude
information to my files. something like

exiftool.exe -77.10 +34.20 c:\Pictures\*.jpg

2. I also use irfanview, and I would love to see something which
incorporates the above procedure into it. ie, add the same location to
multiple files I select.

Would someone help me to geotag my pictures using exiftool or any
other command line tool?

Thanks.

 

Ok, the easiest way to use exiftool to do it is to edit the
individual GPS tags directly. The tags used are:

GPSlatitude (always positive)
GPSlatitudeRef (N or S)
GPSlongitude (always positive)
GPSlongitudeRef (E or W)

Case isn't important in tag names.

So using the values you gave above the command line (without
the line wrap of course) becomes:

exiftool -gpslatitude=77.1 -gpslatituderef=S
-gpslongitude=34.2 -gpslongituderef=E c:\pictures\*.jpg

By default exiftool will rename your originals and write new
modified copies, but if you want to save to the originals
you can add the "-overwrite_original" directive to the start
of the command line.

As always test on a few copies before you use it on your
images, and always have backups available before doing any
changes.

 

Or... ;-)

An even easier method is to use Google Earth to geotag *one*
"template" image. Let's assume this file is called
"template.jpg" and it's in the root of C:.

A simple line like:

exiftool -overwrite_original -tagsfromfile c:\template.jpg
-gps:all c:\pictures\*.jpg

would copy the GPS tags from the "template" file to all the
JPEGs in the target directory.

Probably easier than the first method.

 

You might email Irfan (writer of Irfanview) about this idea. He is
still actively developing this software, and is very accessible.
