Geotagging software adds location data to image and video metadata, allowing users to search for images by location. It can be synced with GPS devices or entered manually, and is useful for organizing photos and finding relevant images online.
Geotagging software is software that adds location data to the metadata associated with a video or image. This data tells people where the image was taken, whether they have the ability to read the metadata. There are a number of geotagging software products available on the market, including freeware and shareware versions. Many of these are designed to interface with photo management software and online photo and file sharing services, providing a variety of functions for the user.
Geographic location can be entered into metadata in several ways. Some software works with a Global Positioning System (GPS) device that can be synchronized with a camera. As people snap photos, GPS records their location, and geotagging software can sync the data later to automatically tag pictures with their locations. This type of geotagging software is good for people who shoot large volumes of images and find it difficult to tag by hand.
Other software lets people enter GPS coordinates, a zip code, or a city name, and can also let visitors geotag images by dragging them to a location on a map. Images can be tagged individually or the software can allow for batch editing so people can work with large groups of images at once. People can also add location notes with some geotagging software programs.
There are several ways to use geotagged images. Online, people can make it easier for other users to find relevant images by geotagging them. When someone searches for a specific region, images taken there will be displayed. Having access to all publicly tagged images in a location can be a powerful tool for everything from finding multiple images of an event to using images to gather evidence for law enforcement.
Photographers may also find it helpful to keep track of where photos were taken for organizational reasons and to ensure they can keep track of photos years after the fact. Someone on a trip can take numerous photos, and five years from now it can be difficult to remember where and when the images were taken. By accessing the metadata, people could search for images taken in a specific place, at a particular time, or with a particular camera. Photo management software usually provides tools that allow people to work with metadata for the purpose of organizing photographs in ways that are meaningful to them.
