Bearing Calculator

This tool calculates the distance, initial bearing, and midpoint between any two GPS coordinates. It accepts decimal degrees, degrees and decimal minutes, and degrees/minutes/seconds formats, making it suitable for a range of coordinate input styles. The result provides the great-circle distance and the compass bearing needed to travel from the starting point to the destination. The output also includes the midpoint coordinate, which can be useful for planning waypoints or rest stops along a route. The tool runs entirely within the browser, so no software installation or account creation is needed to perform the calculations. The interface is straightforward, presenting input fields for starting and destination coordinates side by side with a single action button to generate results. Compared to other bearing calculators, this version is embedded directly on the CacheSleuth geocaching platform, meaning it is tuned for outdoor navigation use cases rather than general academic purposes. It also includes a share link feature and custom marker options that are specific to the site's community focus, which are not typically found on standalone math or GIS calculators.
