This calculation can be useful when trying to determine the distance for logistical purposes (ie delivery service, flights, distance between customers, etc). Where developers & technologists share private knowledge with coworkersProgramming & related technical career opportunitiesIt could have, but my question pertains more to calculating this on a Windows Phone which is a bit different. Finding distances based on Latitude and Longitude. I can't find it anywhere. no floating point processor, working with small microcontrollers) where some trig functions can take an exorbitant amount of CPU time (e.g. the below function is 100% accurate: Beatiful answer, I'd like to point out that the resulting distance is in meters. Buyer beware. I would like to leave the answer as it is, because this is the original .NET code. I'm going to test this out to see if the built in calculation is any better. what would I have to change to directly have the resulting distance in Km instead of miles without having to convert?Thanks for a good solution, I can now use it in my Desktop application.Worked great in my UWP app where I cannot use GeoCoordinate.calculation is 95% true. But there is a simpler and much more accesible way if you aren’t doing very high accuracy calculations. My data is in the following format: Lat Long Origin: 44.844263 -92.914803 Destination: 44.822075 -92.912498 I have tried using the following formulas, which I found online, but it is clear I am using them incorrectly. In order to establish a point, you MUST have latitude and longitude coordinates in one form or the other. – Joe Irby Sep 26 '17 at 18:04. I threw this together as a proof-of-concept in 2002 based on a couple of articles I found on the internet. Here my optimized C# variant (distance in km, without variables and redundant calculations, very close to mathematical expression of Haversine Formular There are times (such as in my work) when computing power is scarce (e.g. site design / logo © 2020 Stack Exchange Inc; user contributions licensed under For a better experience, please enable JavaScript in your browser before proceeding. Should I calculate it in km first and then convert to miles?And here, for those still not satisfied, the original code from .NET-Frameworks For those who are using Xamarin and don't have access to the GeoCoordinate class, you can use the Android Location class instead:Based on Elliot Wood's function, and if anyone is interested in a C function, this one is working...This is an old question, nevertheless the answers did not satisfy me regarding to performance and optimization. You must log in or register to reply here. The formula is the same, but newer method calls like the DistanceTo method aren't necessarily available.Suggest you store pi/180 so you don't have to keep repeating the calculation.Nigel, are you sure that the DistanceTo method will work on the phone? Accuracy is more than good enough for my purposes.Can you provide the formula used for this calculus or maybe some comments about what line does?

GetDistance is the best solution, but in many cases we can't use this Method (e.g. calcul des distances entre 2 lieux ou villes, en fonction de la latitude et longitude, localisation sur la carte et image satellite This method uses spherical triangles and measures the sides and angles of each to calculate the distance between points. 3000+ clock cycles), so when I only need an approximation, especially if if the CPU must not be tied up for a long time, I use this to minimize CPU overhead:Thanks for contributing an answer to Stack Overflow! Universal App). 1. Featured on Meta I didn't think this would be so hard... but gezz! Stack Overflow for Teams is a private, secure spot for you and Are there any good class libraries out there for calculating distance? There are many options available if you want to import these in a GIS and run analysis. When I'm calculating distance, I tend to get an average of 3.3 miles for my calculation whereas other apps are getting 3.5 miles. Ctrl+; enters current date. I recently had a need to calculate distance between a large number of latitude/longitude coordinate pairs. Thanks Nigel!I might ask a wrong question, but in what unit is the result? Could i also have a copy of that excel formula as i am trying to do the same thing.If anyone still stumbles on this thread as I just did, this formula seems easier these days for me.
