The most common way to embed data into an image file is using the Exchangeable Image File Format, or EXIF. But where's fun in that? This article explores how to get at that data yourself. You can then get that data back in feeds. Some photo upload sites, such as Panoramio, Picasa Web Albums, and Flickr, will parse out GPS data automatically and use it to geotag a photo. Camera phones like the iPhone and phones using the Android operating system, like T-Mobile's G1, embed that data automatically. In the last few years, people have found ways to add geographic data to that information, either embedded by the camera manufacturers, such as some Ricoh and Nikon cameras, or through devices such as GPS loggers and the EyeFi Explore. They also tag those videos and photos with metadata about the camera and its settings. Many users don't realize it, but they do more than just take pictures and video. Introductionĭigital cameras are pretty amazing things. The code in this article relies on an open-source Python library, EXIF.py. While the sample code is written in Python, many similar libraries exist in other programming languages, so it shouldn't be a problem to translate this code into another language. This tutorial teaches you how to use geotagged photos to create KML PhotoOverlays.
