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
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.
- Connect AMOD to Mac via USB.
- Connect Nikon D40 (or memory card reader) to Mac via USB.
- Close iPhoto (optional, but recommended).
- Launch HoudahGeo.
- Drag and Drop photos onto HoudahGeo.
- Click "LOAD GPS FROM FILE". Browse & import AMOD log file.
- Presuming your clocks are in sync, HoudahGeo will now display Long/Lat/Alt information from your GPS track to correspond with each photo.
- Click "WRITE EXIF/XMP/IPTC TAGS" to save the geo data to the photos.
- Close HoudahGeo.
- 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.
