Apple has announced plans to cease development of Aperture. Corel and Adobe have already started courting photography enthusiasts and professionals with their respective photo management and editing products.

Before moving away from Aperture you will want to safeguard geotags currently stored with Aperture Places. HoudahGeo can copy these to industry-standard EXIF / XMP tags embedded within your JPEG or RAW image files. There geotags will be available for other photo management and editing tools to pick up.

Geocoding using iPhone reference photos

HoudahGeo offers several options for geocoding your photos: automatic using GPS track logs, using GPS waypoints, using built-in maps, using Google Earth, etc.

You may however find the camera lacking when compared to your regular digital camera. Your preferred camera on the other hand lacks a GPS chip. HoudahGeo can match up geocoded photos from your iPhone with photos taken around the same time using your regular camera. It can thus assume both were taken at the same location.
