WebJan 27, 2016 · All of the Haversine formulas use a sphere. To match that in ArcGIS, you'd have to have the data's CRS use the same sphere model. With lat/lon data, ArcGIS is using a geodesic calculation (roughly Vincenty). You're not going to be able to match it even by adjusting the sphere radius in a Haversine formula. – mkennedy Jan 26, 2016 at 17:12 3 WebHaversine hv = new Haversine(); double result = hv.Distance(pos1, pos2, DistanceType.Kilometers); Here is the code for the class: using System; namespace …

WebWe can derive the haversine formula to calculate the distance d between two points as follows: a = sin²(Δlat/2) + cos(lat1).cos(lt2).sin²(Δlong/2) c = 2.atan2(√a, √(1−a)) d = R.c In the formula above, the values are calculated as follows: Δlat = lat1 − lat2 Δlong = long1 − long2 R is the radius of the earth, that is, 6,371 kilometers.

WebThe only potential hitch is to make sure you and your software platform agree on what "cos" means: it had better interpret cos (10) as the cosine of 10 degrees, not 10 radians! (If not, 10 degrees = 10 * pi / 180 radians illustrates the simple conversion.)
