The high-resolution Pro G3 had a 3.34-megapixel image sensor and retailed for $1,149 with the GPS add-on. Ricoh released a GPS-enabled camera in early 2005. Some form of GPS-enabled cameras have been around since the early- to mid-2000s. If a relatively small phone can have built-in GPS capabilities, surely the feature could easily be fit into the electronic picture-making boxes that we sling around our neck or over our shoulder. Although the phones that most of us carry around in our pockets on a daily basis have the ability to pinpoint where on Earth we are, most cameras still do not have this feature. With all the technological advancements today, one would think that all modern cameras would have a built-in GPS feature. That can be very useful for keeping track of where you have been and navigating back to a location in the future. After importing an image to a computer, the GPS information can be used to pinpoint the image location on a map. That's the same place where you find the shutter speed, aperture, ISO, and tons of other information. GPS information captured by a camera is stored in the exchangeable image file format (EXIF) data for an image. The data obtained is typically latitude and longitude, which provides fairly accurate (usually at least within 10 meters) location information. Some cameras without an internal GPS chip have the option of connecting an external module for receiving the GPS coordinate information. GPS receivers, such as those found in select camera bodies, use the information from several of the satellites to calculate a user's location. There are at least 24 global positioning system (GPS) satellites orbiting the earth, each transmitting a unique signal. Maybe a more appropriate title should be “How Geotagging Should Work”, since it is such an under-utilized (or ignored) feature. Tools of the GPS trade (well…besides the camera, which doesn't have GPS built in). This article will take an in-depth look at how geotagging works, which camera bodies currently on the market include in-camera or external geotagging features, and alternative methods for attaching location information to images if your camera doesn't have these features. Fortunately, even though manufacturers have generally seemed to neglect including a geotagging feature in their camera bodies, there are other methods photographers can use to gather this information. There are a few methods that photographers can use to geotag images, the least of which includes using an in-camera feature. Landscape and travel photographers find this to be especially useful information to navigate back to a location or to provide details about where a photo was captured. Geotags provide important information that allow the location of an image to be pinpointed on the globe. Geotagging is the process of adding geographical coordinates to a photograph.
