Latitude/Longitude Distance Calculator Enter latitude and longitude of two points, select the desired units: nautical miles (n mi), statute miles (sm), or kilometers (km) and click Compute. Latitudes and longitudes may be entered in any of three different formats, decimal degrees (rutlib6.com), degrees and decimal minutes (DD:rutlib6.com) or degrees. Jan 17,  · We can calculate the distance between two longitude and latitude co-ordinates using a trigonometric calculation. It's a complex formula so in this post, we'll find out how exactly this works, including a verification of the result. We'll see how to perform this distance .

I'm calculating what to write in thank you cards for wedding gifts distance between two GeoCoordinates. I'm testing my app against other apps. When I'm calculating distance, I tend to get an average of 3. It's a big difference for the calculation I'm trying to perform.

Are there any good class libraries out there for calculating distance? I'm cqlculate it like this in C :. The GeoCoordinate class. Distancs is the best solutionbut in many distabce we can't use this Method e. Universal App. Pseudocode of the Algorithm to calculate the distance between to coorindates:. And here, for those still not satisfied like methe original code from. For those who are using Xamarin and don't have access to the GeoCoordinate class, you can use the Android Location class instead:.

There's this library GeoCoordinate for these platforms:. Based on Elliot Wood's longitudee, 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. There are times such as in my work when computing power is scarce e. Stack Overflow for Teams — Collaborate and share knowledge with a private group. Create a free Team What is Teams?

It could have, but my question pertains ditance to calculating this on a Windows Phone which is a bit different. The formula is the same, but newer method calls like the DistanceTo longltude aren't necessarily available.

You need to reference System. Improve this answer. Tomas Kubes 20k 14 14 gold badges 90 90 silver badges bronze badges. Nigel Sampson Nigel Sampson Nigel, are you sure that the DistanceTo method will work on the phone? I thought it used the 2. Calcukate did check what does gneiss look like and the GeoCordinate for the device has a GetDistanceTo method which is what you had referenced but not what you have above.

No big deal. I'm going to test this out to see if the built in calculation is any better. Thanks Nigel! I might ask a wrong question, but in what unit is the result?

Is it Miles, or Kilometers. I can't find it anywhere. SaeedNeamati - was looking for this too, according to msdn. Yes, GeoCoordinate. GetDistanceTo returns the value in meters.

Accuracy is more than good enough for my purposes. Show 4 more comments. DistanceTo new Coordinates Trom - targetCoordinates. David Leitner David Leitner 2, 1 1 gold badge 15 15 silver badges 26 26 bronze badges.

Can you provide the formula used for this calculus or maybe some comments about what line does? Thanks for a good solution, I can now use it in my Desktop application. Mar 2 '18 at Add a comment.

Latitude and longitude basics

Jun 04,  · Calculate Distance Between Two Points Using Latitude and Longitude. In this post, we show the formula to calculate the shortest distance between two points using Latitude and Longitude. This calculation can be useful when trying to determine the distance for logistical purposes (ie delivery service, flights, distance between customers, etc). Mar 03,  · 'OUTPUT: Distance between the ' two points in Meters. ' '===== ' Calculate geodesic distance (in m) ' between two points specified by ' latitude/longitude (in numeric ' [decimal] degrees) ' using Vincenty inverse formula ' for ellipsoids '===== ' Code has been ported by lost_species ' from rutlib6.com to VBA ' from javascript. Calculating Distance between Latitude and Longitude points double Lat1 = rutlib6.comle (latitude); double Long1 = rutlib6.comle (longitude); double Lat2 = ; double Long2 = ; double circumference = ; // Earth's circumference at the equator in km double distance = ; double latitude1Rad = DegreesToRadians (Lat1.

So there are hell lot of examples in our day to day life where we have to calculate the distance between two points and if you are working with any of the POI datasets as a Data Scientist then you might encounter such uses cases frequently. Look at that aerial distance Black Bar Scale that google displays for the distance between two points.

Here are three abstractions which is considered for calculating the distance between two lat and longs:. The shortest distance between two points in a plain is a straight line and we can use Pythagoras Theorem to calculate the distance between two points.

Greater Circle Distance Algorithms are used to calculate the distance between two points which assumes earth as a spherical object. Haversine Algorithm is used to calculate this distance. An ellipsoid approximates the surface of the earth much better than a sphere or a flat surface does. The shortest distance along the surface of an ellipsoid between two points on the surface is along the geodesic. Vincenty Algorithm is used to calculate this distance.

To calculate the distance between two points there are two popular algorithm Haversine and Geodesic distance is used:. Haversine computes the great circle distance on a sphere while Vincenty computes the shortest geodesic distance on the surface of an ellipsoid of revolution. This returns the minimum spherical distance between two points or multipoints arguments on a sphere in metres.

The points has to be entered within the following range:. Google also calculates the same distance The calculated value is in Degress and to convert that to KM I have multiplied the result by i. As per wikipedia,The haversine formula determines the great-circle distance between two points on a sphere given their longitudes and latitudes. Important in navigation, it is a special case of a more general formula in spherical trigonometry, the law of haversines, that relates the sides and angles of spherical triangles.

The geodesic distance is the shortest distance on the surface of an ellipsoidal model of the earth. The default algorithm uses the method is given by Karney geodesic.

The Geodesic distance is also 28 KM which is same as the Spherical and Pythagoras distance that we calculated above. Jersey City here using haversine formula. For this task, I have taken 4 Walmarts Latitude and Longitudes in a Pandas dataframe as shown in the image below:.

Using the Haversine formula explained above it returned two walmarts from the above dataframe, One Walmart is in New York and the other one is in Bayonne which is within the radius we are looking for since both New York and Bayonne lies within a radial distance of 50 Kms from Jersey City.

Share this. Here are three abstractions which is considered for calculating the distance between two lat and longs: a Flat surface The shortest distance between two points in a plain is a straight line and we can use Pythagoras Theorem to calculate the distance between two points. To calculate the distance between two points there are two popular algorithm Haversine and Geodesic distance is used: Haversine computes the great circle distance on a sphere while Vincenty computes the shortest geodesic distance on the surface of an ellipsoid of revolution.
