HoudahGeo is a one-stop photo geocoding solution for OS X. Export geotags to EXIF, XMP and IPTC. GPS device optional.

Just like a GPS-enabled camera, HoudahGeo records latitude, longitude, and altitude information right to your image data file. Don't have a GPS device? No problem! Just drop a pin on the map where you took your photo and HoudahGeo will tag it with the correct location.


  • Remember where you took your photos
  • Show friends, family and clients photos pinned to a map
  • Geotag photos of properties you sell, bridges that need repair, ...
  • Use geotags to more...

I have been using "MyTracks" for several months and never really got into it. The usability is okay, but if you use the software only every now and then the UI, especially with the "Fotoablage" is - let's call it a bit complicated.

HoudahGeo is different. The UI is much more easy to understand and locating pictures by simply pointing to the place they were taken is really easy and straight forward. The whole workflow is easy - import the pictures - geolocate them (several possible ways) - write the EXIF to the files or use other ways of exporting the data.
Also the support is quick and helpful. I'll contact them again with a few ideas. Overall a very nice piece of software.

The app is really easy to use. If you get confused on how to get it to work, check the Screencast on the developer's website and you'll see it's really easy.

So far I haven't encountered any problem and I can say it's the best on its job.

Not only is the program excellent, but the support is top grade. I had a problem with the v3 upgrade not loading (it turned out that there was a password-locked file in the Pictures folder that HoudahGeo consults when starting up) and the developer worked with me over several days and numerous e-mails to track down the solution. Excellent all around.

Seems like they rushed into releasing this version without really running it through it's paces. Makes you wonder if it really worth the price of an upgrade.

Are you experiencing any particular problem?

HoudahGeo 3.0 had a long beta period. Yet some bugs fell through the cracks. Hence the quick release of the bug fix updates.


It was a comment not a review.

It works well and does what is advertised, It is not totally automatic and requires a little understanding og the program for the way I use it but easily learned.

I am using this regularly to georeference lots of photos. I use a Garmin GPS and save the tracks, and then georeference from the tracks. There are lots of features of this app that I have not used, but the ones I do use just work. However, I have found, after georeferencing thousands of photos, a few gripes.

1. If you georeference from GPS tracks, you have to remember to set your camera's clock before you start taking photos. If you end up changing the clock after you start, you need to set up two documents--one for before and one for after changing the clock. (You better write down when you changed it!) Likewise, if you have 2 cameras, you need to set up separate documents for each camera unless they are exactly synchronized--which is clunky (the delta between camera and GPS time is constant for each document). A better interface would be to have the delta default to the same, but be able to change it for groups of photos. Then you could keep all the images from the same trip, but different cameras, in the same document.

If you are GPSing from Google Earth, the interface is confusing. If you click on an image that has been georeferenced, then Google Earth is activated, and your next keystroke goes to Google Earth. But it hasn't been georeferenced, then Houdahgeo keeps control. This is very strange behavior--you run through a bunch of photos trying to remember where you took them, and use the down-arrow to scroll through them. When you reach an image that has been georeferenced, suddenly the scrolling stops, because Google Earth is now getting the keystrokes.

This is a file-based program (which is probably right), so it saves a reference to photos and various data for each photo (like Lat/Lon) in the file. You then write out the data when you are done (so that, e.g., the Lat/Lon will be included when the photo is uploaded to Flickr). However, there is no indication within the program whether the Lat/Lon in the image is the same as in the Houdahgeo file. So it is very easy to update the Lat/Lon in Houdahgeo and forget to export the change, so your images have the wrong data.

Overall, a stable and very useful program. The developers have done lots of work to make sure it interfaces as well as possible with various photo programs like Lightroom and iPhoto (which I don't use). But it could use a complete review of its user interface to make easier to understand.

Also, I recommend that you become familiar with exiftool, as it is the easiest way to change the date/time in a photo if you set your camera's clock incorrectly, which you should do before you run Houdahgeo.

I can't figure out how to edit my review, so I am "replying" to myself.

I am less infatuated with Houdahtool now that I am using it more. Two problems:

1) Houdahgeo goes out of its way to not update the "file modified" date on files when it writes out the gps location data. This means that you cannot figure out which files were modified when, and back-up software may not catch the changes, so the changes may not be backed up.

I have communicated with the author about this issue, and, while he indicated that he understood the problem, he has not addressed it. It would be easy to address by adding a preference to the program.

2) I have had some issues with errors in the programs due to various xmp metadata fields being in the file. The author showed little interest in figuring them out, so I moved on to another program that does not have these problems.

In summary, while HoudahGeo is a nice single-purpose program at a good price, seems like the author is not able or willing to put the effort into making it better. If it suits your needs, great. If not, you could look into PhotoLinker.


By default, HoudahGeo tries to preserve file modification dates while writing metadata. Even though you have written new data to your image files, their modification dates remain unchanged.
If you wish to see the modification date updated during EXIF/XMP export, you may disable this feature.

To update the eePreserveDates setting: Quit HoudahGeo.app. Launch /Applications/Utilities/Terminal.app. Paste the following line to the command line in Terminal.app. Hit Return.

defaults write com.houdah.HoudahGeo eePreserveDates -bool NO

HoudahGeo just works. I used it every day for 3 weeks as I processed vacation photos. Import the photos, import the GPS data from the logger and HoudahGeo takes it from there. If you're just getting started here's a huge tip, set your camera clock before you leave and don't change it while traveling.

Why does the operating system ask me if I want to allow incoming connections for HoudahGeo?

When using the "Geocode using Google Earth" feature, HoudahGeo starts up a HTTP server to communicate with Google Earth. This connection is incoming to HoudahGeo, but coming locally from your copy of Google Earth. It is not advertised to the outside world.

Much more accurate and easier to use than iPhoto's geotagging. Thank you Houdah!
