The information can be entered by directly giving the coordinates or by selecting a location from a map using software tools.
Wireless data transfer allows real-time mapping of media. Transferring images from cell phones to social networking sites is gaining popularity. Applications for real-time mapping include travel, real estate, geosocial networking, people tracking, security, and geofencing. Geotagging allows presenting the geotagged media via a map.
GPS unit showing basic way point and tracking information as typically required for outdoor sport and recreational use. Heavy equipment can use GNSS in construction, mining and precision agriculture. The blades and buckets of construction equipment are controlled automatically in GNSS-based machine guidance systems.
A GPS tracking unit, geotracking unit, satellite tracking unit, or simply tracker is a navigation device normally on a vehicle, asset, person or animal that uses satellite navigation to determine its movement and determine its WGS84 UTM geographic position (geotracking) to determine its location.

The application can provide continuous tracking and send notifications if the target leaves a designated (or "fenced-in") area. [120] Geotagging: applies location coordinates to digital objects such as photographs (in Exif data) and other documents for purposes such as creating map overlays with devices like Nikon GP-1.
