      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.
