ELL_GEO_2PTSEP

Name


      ELL_GEO_2PTSEP

Purpose


      Find distance between two points along a geodesic.

Category


Calling Sequence


      d = ell_geo_2ptsep(p1, p2)

Inputs


      p1 = Point 1 on geodesic {lon:lon, lat:lat}. in
      p2 = Point 2 on geodesic {lon:lon, lat:lat}. in
        The points are in structures.

Keyword Parameters


Keywords


        AZI1=a1 Returned azimuth from p1 to pm.
        AZI2=a2 Returned azimuth from pm to p1.

Outputs


      d = Returned distance in meters. out

Common Blocks


Notes


      Note: p1 and p2 may be the same point and this will
        still work. The routine ell_ll2rb will not handle
        this case so use this instead.
