Geotag your DSLR shots
While we know our iPhone photos will be properly tagged with location data, that’s not guaranteed with DSLR
shots. Enter HoudahGeo 5, which imports images from cameras and SD cards, as well as folders and photo libraries on your Mac. It uses a variety of methods to work out where photos were taken, then adds the appropriate EXIF, XMP, and IPTC metadata to JPEG or raw files.
Geotagging automatically kicks in when used with supported GPS track loggers, but there’s another method if you don’t want to invest in such accessories. At each location as you travel, simply take a photo with your iPhone or mobile-networkable iPad, then load those images into the same HoudahGeo project as your DSLR files; click the Geocode from Reference Photos button on the toolbar and the software will match them up for you.
HoudahGeo currently can’t write metadata directly to your Photos libraries, an Apple restriction that the developer says will be lifted with the release of macOS Sierra; iPhoto, Aperture, and Lightroom libraries work just fine, however. Sierra delivers Apple Maps data alongside MapBox and MapQuest for robust map, satellite and hybrid views, so we hope to see these reflected in a HoudahGeo update soon.
You can use GPS track loggers, reference photos, or search for location data from Google Earth.
