GMap Lat/Lon is a small glue module that provides Latitude and Longitude Views fields for nodes with gmap_cck fields. Haversine formula – Calculate geographic distance on earth Law of Haversine: To derive law of Haversine one needs to start the calculation with spherical law of cosine i. Recently the work I have been doing requires a higher degree of accuracy than which the haversine method I was using could provide. The great circle distance d will be in the same units as R. MPI Haversine for distance calculation in C [closed] Tag: c , mpi I'm pretty new to MPI, so I tried to do Haversine distance calculating method in C, so far it seems work but I notice the result is incorrect, maybe something wrong with MPI method i used, here's my code :. The distance line color can be defined by the user. The haversine formula is a very accurate way of computing distances between two points on the surface of a sphere using the latitude and longitude of the two points.
