Geocoding Geotagging Photos with GPS Coordinates
The process of geocoding or geotagging photos is becoming increasingly popular. The terms can be used interchangeably, and is the process of coding or tagging digital photos with information about the location where the photos were taken. Typically that information is in the form of GPS coordinates.
There are a variety of ways that geocoding or geotagging “meta” information can be added to your digital photos. Some software will take a tracklog from your GPS device and match up your coordinates with a particular photo based on the date and time recorded by both devices. So if a photo was shot yesterday at 11:45 am the software will then read through your GPS tracklog and determine your coordinates at that time, and add the information to the meta data stored with the photograph.
Which are the other ways some software might work? Is it posible to place coordinates on digital pictures taken previously if you know locations?
