21 gru 2022 · d = rcos-1[cosA.cosB.cos (X-Y) + sinA.sinB] where, r represents the radius of Earth which is approximately 6400 kilometers or 3959 miles, A and B show the latitude of the place, And lastly, the longitudes are presented by X and Y. How to Find Great Circle Distance Using Excel Formula: Step-by-Step Procedures.
As found here by BrianAdkins, this Excel formula to calculate distance between two latitude/longitude points works for me both in LibreOffice Calc and Microsoft Excel 2013: =ACOS(COS(RADIANS(90-A1))*COS(RADIANS(90-A2))+SIN(RADIANS(90-A1))*SIN(RADIANS(90-A2))*COS(RADIANS(B1-B2)))*6371.
28 mar 2016 · After much googling most of what I can find either relates to calculating distance, or calculates using an equirectangular projection. The closest I could find is the formula: θ = atan2( sin Δλ ⋅ cos φ2 , cos φ1 ⋅ sin φ2 − sin φ1 ⋅ cos φ2 ⋅ cos Δλ ) which when using excel needs to be reversed: =ATAN2(COS(lat1)*SIN(lat2)-SIN ...

Excel Formulas for Distance. There are numerous Excel worksheet functions that will return an initial heading from one point to the destination point for a Great Circle path between them and similar formulas to return the distance between them.
Q: How does the Great Circle Mapper calculate distances and paths? A: The Great Circle Mapper uses formulae developed by Thaddeus Vincenty to perform geodesic calculations with modifications by Charles Karney based on work by Friedrich Bessel to improve performance and accuracy.
