Maybe you are better in taking care of setting the embedded clock. At least my camera is almost always off a little. In reality there are a few problems which you need to keep in mind.įirst, most cameras don’t have the exact time (GPS devices however have it, they are basically showing the time from atomic clocks sent by the GPS system). So all we have to do is take the time stamp of the image, look-up the position of the GPS tracker at that point in time and assume that camera and GPS device were in close proximity. As you probably know, the EXIF data of the images also contains a time stamp. Basically it is a mapping between time and position, telling us where the device has been at a given time. The GPS receiver calculates its current position based on the information it receives from some satellites and stores them in a GPX file, together with the current date and time (and some other data which we are not interested in). First of all let me explain what these GPX files are. So, let me explain the intended workflow to assign geo locations to your images making use of the GPX file stored by your GPS tracker. Or just keep reading, it might be interesting after all. If you want to tag the images manually you can skip the next two paragraphs, too. If you are lucky enough to have a camera which already stores coordinates in the EXIF data of the images you can skip this paragraph and also the next one.

If you just want to try this you can take the manual route but if you plan to geotag thousand of pictures taken during your vacation I would advice to spend a little money on some hardware.

Basically there are two ways to do that: for one you can do it manually for every image or you can use a GPS receiver to record a GPX track while you take your pictures (you can either use a cheap GPS logger or a full fledged GPS receiver, maybe even your phone). So we somehow have to assign geo locations to the images. While the easiest way to get geotagged images is using a camera with a built-in GPS receiver (or an external receiver attached to the camera) most people don’t have that. So everyone using either the experimental builds from Pascal’s PPA, compiles darktable from git or has some other way to run the latest and greatest development version of darktable can try all of this stuff.Ī full fledged GPS receiver and a small logger

Granted, a few details are still missing and I wouldn’t be surprised if a few quirks and bugs can be found, too, but nevertheless I decided that the code was ready for prime time and merged it back into master. Since it would be a pity to throw away all the great work Henrik did I kind of adopted the branch and set sails to add the missing bits and pieces to make geotagging a new feature of darktable.

Things started to come together nicely and everything looked really promising, but unfortunately he was a little short in free time so the progress stalled and the code started to bitrot. Some day however Henrik decided to give it a try and started work in his geo branch. While that is a nifty feature for sure and really helpful when you take pictures outside of a studio we always had to say something along the lines of “sorry, we don’t have that yet”.

PS:IE may not support drag and drop but in that case, you can click the “camera icon” in the Google search box to manually upload a picture to Google Images for analysis.For quite some time people have asked us for a way to geotag their images from within darktable. In all other cases, you will at least know the original source of that image and that could offer enough hints for you to guess the actual location on your own. If that photograph is of some popular destination, Google will mention the possible location of that image above the search results (see screenshot). Go to Reverse Image Search and upload any image – either from your desktop or another web page. The same feature of Google Images can sometimes help you uncover the location of a photograph as well. You probably know that Google offers Similar Image search to help discover images that are visually similar to your source image. Sometimes the EXIF data embedded in an image file can help you determine the location but there’s another alternative that is more likely to work. The only problem is that the web photograph carries no text caption and you therefore have no clue of the location where that picture was possible taken. Say you are exploring interesting places on the Internet and come across a gorgeous destination that you would like to visit sometime in future.
