I can download an image you uploaded to a social networking site and find out the manufacturer of your phone, GPS time stamp and GPS date stamp. There is nothing more deceptive than an obvious fact.Ī photo tells a lot more about you to the world than you might want to share. You can see that both have the correct data, but the one on the left (which works in all places) has the data inside the main GPS tagged group, whereas the one on the right has some different Composite data and XMP-exif data which isn’t standard enough for Flickr to pick up.The world collectively takes 14 trillion photos annually. The text on the left if from the data of the file that works in all places (Flickr and Geosetter), and the text on the right is from the file that only worked in Geosetter. Just a FYI, if you run the above command to output the grouped data on the files, the below is what you see. (see my next post, coming soon) Additional info #HOW TO USE EXIFTOOL TO SEE GPS COORDINATES IN .MOV HOW TO#Next up is to figure out how to do so from within Powershell. Now that works in both Flickr and Geosetter. You can see that the parameters include a wildcard and what that allows is to only give the lat/lon and it will then work out the N/E/S/W based on the -ve or ve values given. exiftool -a -G1 -s E:\CameraAddGPS\TestFolder\before\photos\DSC00939.JPG Correct command to insert GPS with only lat/lon exiftool -GPSLatitude*=56.9359839838 -GPSLongitude*=-4.4651045874 -GPSAltitude*=30.42 DSC00320.JPG Had I known this command at the start which outputs exif tags in groups that would have help hugely in debugging the situation. WRONG, the reason it failed was not down to the timestamp! On adding the timestamp, Geosetter also updated the geotags which made it work in Flickr. #HOW TO USE EXIFTOOL TO SEE GPS COORDINATES IN .MOV PROFESSIONAL#Perhaps Flickr being a bit more professional than a free app, it respected the rules in a stricter fashion. So now that it worked in both GeoSetter and Flickr I presumed that the reason it failed initially in Flickr was due to some timestamp/date issues. What on earth is going on? Debugging/Comparing tagsįirstly I went to look at the GPS location while inside of GeoSetter and if I tried to change it there, it gave me the following warning.Īfter setting this in GeoSetter, the file with no changes to GPS location then worked in Flickr! I load the exact same file into Flickr, and yet again, the same as the first command it places the photo’s location into the North Sea! ? Trying this in various ways and same thing each time. I load the file into GeoSetter and it shows me exactly where I expect the photos location to be. Googling, I can see that if I use the xmp commands, they can handle negative values, as in it does not require the reference values of N/S/E/W exiftool -xmp:gpslongitude=-4.4651045874 -xmp:gpslatitude=56.9359839838 -GPSAltitude=30.42 DSC00320.JPGĪgain no errors. But this command only takes the number as if it was positive! It completely ignores that fact I gave it a negative value! Next option In my case the data is negative, so that means it’s West and not East. Reason it failed is that GPSLatitude/GPSLongitude needs a reference to it’s place in the world, as in which quadrant it’s in. That location is in Scotland, but the map is showing it as somewhere in the middle of the North Sea! So I run the above, it works – sort of! No errors, I take the image, drop it into either Flickr or a free app that shows the location the photo has been tagged with. Means you don’t have to worry about paths. Important to note that I’ve copied the exiftool.exe into the same folder as the image and the above command is run from that same folder. So you pull out the latitude and longitude and come up with the following: exiftool -exif:gpslongitude=-4.4651045874 -exif:gpslatitude=56.9359839838 -GPSAltitude=30.42 DSC00320.JPG This is the XML node containing the data Next up, is that you are going to test it working on a single image and most of the examples I was reading involved the command line. This does the actual adding, you just need to know what and how to call it. It works on the command lineįirst step is to get the Exiftool from here if you wish to follow along. See previous post which is another hurdle I had to overcome. I’ll highlight some of the issues I hit along my journey so you do not have to. The concept is simple, yet there are numerous hurdles to overcome. You have some data and you wish to automate adding that data to your photos. So you’ve got some photos, those photos do not have any location data.
