Houdah Software releases HoudahGeo 5.1, a major upgrade to the photo geotagging tool for Mac. HoudahGeo tags photos with location coordinates and names. Standard EXIF, XMP and IPTC geotags allow photo cataloging tools to organize and later find photos by location. HoudahGeo integrates with Apple Photos, iPhoto, Aperture and Adobe Lightroom. Version 5.1 now adds locations to photos in the Apple Photos library on macOS Sierra, as well as offers Apple Maps in addition to MapBox maps. HoudahGeo 5.1 is $39.00 and can be downloaded from their website.
