Locations that are (nearly) antipodal may produce meaningless results. DistanceTo (Dest As LocationF) As Float Returns the approximate distance in meters between this location and the given location. Distance is defined using the WGS84 ellipsoid. HasAccuracy As Boolean Returns true if this location

From the Android documentation for Location.distanceTo https://developer.android..html#distanceTo(android.location.Location) Returns the approximate distance in meters between this location and the given location. Distance is defined using the WGS84 ellipsoid.

link: I thought they did. Two easy no-math-required tests: What bearing do you get if you travel to a different longitude at the same latitude (other than

To get more precise results you could have used the DistanceTo method from the GPS libary. Private Location1, Location2 As Location Location1.Initialize(Lat1, Lng1) Location2.Initialize(Lat2, Lng2) Distance = Location1.DistanceTo(Location2)
link: I read somewhere on the forum that DistanceTo wasn't as accurate, if that's been updated, thats great. I use my function in B4A as well as B4J server,

Invece di usare "Location.DistanceTo", ti consiglio di usare questo: https://www.b4x..31499/#content questo perchè "Location.DistanceTo" ti da sempre la distanza in linia diretta da un punto all'altro.

Dim l1 As Location l1.Initialize l1.Latitude = 45.1 l1.Longitude = 8 Dim l2 As Location l2.Initialize l2.Latitude = 45.2 l2.Longitude = 8 Log("l1.DistanceTo(l2): " & l1.DistanceTo(l2))

Location.DistanceTo in smaller walking applications using seconds isn't very accurate. The course part of the GPS library works well to identify turns or changes in direction. There are some good examples of heavy math on the forum. They give consistent reliable results. The graphic below uses L
link: The lazy among us are happy with the accuracy of the math-light method of calling Location.DistanceTo and appreciative that it returns SI units too ?
link: Now that you've added that longitudinal adjustment to your solution, I agree. Not sure why you didn't fix the other two issues while you were there.
link: I can vouch for it working great in the southern hemisphere, albeit that is mostly whilst driving. Do you have an example of two (lat, lon) points wh

Dim l1, l2 As Location l1.Initialize2(gmap.MyLocation.Latitude,gmap.MyLocation.Longitude) l2.Initialize2(RootMap.Get("LatitudB"), RootMap.Get("LongitudB")) 'ahora necesitamos la distancia entre nuestra ubicación y la ubicación de destino

You can use: Distance = CenterLocation.DistanceTo(LocationToCheck) If Distance <= Radius Then ' insides Else ' outsides End If You know the location of your center and you know the locations to check, so can calculate the distance between those with DistanceTo method of the Location object
link: What result I get? I changed the center point and radius, I want to check the location inside the circle or not, how? I want a result.

Hi All I think there is a problem with the DistanceTo method in Location. When I run the following code I get a return value of 7482515 for something that is only 52ish meters away. Any ideas what may be wrong here? Thanks Dim BigBenLongitude As Double = 51.500770 Dim BigBenLatitude As D

You can create two Location objects (GPS library) and then calculate the distance with Location1.DistanceTo(Location2).
