Calculating distance between Lat Long points

[caunchman]

I'm wondering if anyone out there has done this before in LabVIEW.  Does anyone have a model of the "Great Circle" calculation?  I have a file of lat/long points that I need to calculate the distance between.  Any help??

V/r,

Chris

I haven't done it in LV, but if you go to Wikipedia and search for Great Circle Distance you'll find the formual and an example.
