This article shows you how to use Excel to work with coordinates and calculate the distances between locations for advanced mapping problems  it is pretty easy with only a handful of formulas. See my point?. Someone told me that I could also find the bearing using the same data. The ‘versed sine’ is 1−cosθ , and the ‘halfversedsine’ is (1−cosθ)/2 = sin²(θ/2) as used above. Other ellipsoids offering a better fit to the local geoid include Airy (1830) in the UK, International 1924 in much of Europe, Clarke (1880) in Africa, and GRS67 in South America. Feb 15, 2019. Let’s use the simple Haversine formula to calculate approximately how far I will be travelling to follow the boys in green this summer. The haversine formula determines the greatcircle distance between two points on a sphere given their longitudes and latitudes. Ara PHP 5,603 views. Marine Navigation and Ocean Voyaging Resources. 2016 Update The code and the Xcode project for this article is now also available on GitHub. A common feature for modern applications is the need to supply the user with an accurate navigational distance between themselves and another endpoint, especially when providing an ETA for an item they have purchased using said piece of software. How do I calculate the distance between two points specified by latitude and longitude? For clarification, I'd like the distance in kilometers; the points use the WGS84 system and I'd like to understand the relative accuracies of the approaches available. I am trying to calculate the distance between two lat/long points at sea (so in nautical miles). Excel's MIN IF Array Formula Example. To travel the shortest distance between any two points on the surface of a sphere you need imagine a circle passing through both of those points which has its centre at the same point as the sphere and travel along its route. I need to develop a service that calculate the distances of my current location to several points nearby.
