My Nikon D40 Geotag Workflow For Mac

With the rise of geotagging on photo sharing sites like Flickr and Locr and the new Map functionality of iPhoto 09, I have finally gotten my geotag workflow ironed out for the Nikon D40 using my Amod AGL3080 GPS Data Logger.

If you're looking to use a handheld gps to geotag your pictures, I hope my Mac workflow helps.

Geotag Workflow for Nikon D40 & AMOD AGL3080 for Mac

Tools Used:
Amod AGL3080 GPS Data Logger – I got mine on Amazon
Nikon D40 camera
– Again… amazon.
HoudahGeo software – free demo will export five images, but you'll definitely want to upgrade

Workflow:
Note: This workflow presumes you are already competent with the Nikon camera & AMOD GPS datalogger and further presumes that your camera's clock is in sync with the GPS clock. If your clocks are not in sync, you can flex within HoudahGeo, however, I am not referencing that adjustment.

This workflow will work with any iPhoto compatible image format, including JPG and RAW.

  1. Connect AMOD to Mac via USB.
  2. Connect Nikon D40 (or memory card reader) to Mac via USB.
  3. Close iPhoto (optional, but recommended).
  4. Launch HoudahGeo.
  5. Drag and Drop photos onto HoudahGeo.
  6. Click "LOAD GPS FROM FILE". Browse & import AMOD log file.
  7. Presuming your clocks are in sync, HoudahGeo will now display Long/Lat/Alt information from your GPS track to correspond with each photo.
  8. Click "WRITE EXIF/XMP/IPTC TAGS" to save the geo data to the photos.
  9. Close HoudahGeo.
  10. Import images into iPhoto. Each tagged image will be visibile in iPhoto Places.

This is a very simple workflow, one which I will likely automate further.

Please note that you can also manually geotag your images in HoudahGeo using a map overlay and/or Google Earth.

For a more detail example of how to import & tag using HoudahGeo, please see the screenshots and screencast provided by HoudahGeo.
