ELL_CRV_SPLIT

ELL_CRV_SPLIT

Name


      ELL_CRV_SPLIT

Purpose


      Split a curve with an azimuth (geodesic or loxodromic).

Category


Calling Sequence


      ell_crv_split, lonc,latc, c, az

Inputs


      lonc, latc = Arrays of lon,lat for a curve. in
      c = Refernce point in a structure (lon:lon,lat:lat}. in
      az = Azimuth from point c. in

Keyword Parameters


Keywords


        LONL=lonl, LATL=latl Returned points of curve left of azi.
        LONR=lonr, LATR=latr Returned points of curve right of azi.
        NL=nl, NR=nr Number of points in left and right secctions.
        INT=p Intersection point of the curve and azimuth returned
          in a structure (lon:lon,lat:lat}.
        /LOX Use loxodromic azimuth (else geodesic azimuth).
        ERROR=err Error flag: 0=ok.

Notes


      Notes: An azimuth from point c is used to split the given
        curve into two parts, that left of the azimuth line, and
        that right of the azimuth line as seen from point c.
        The interpolated point is included in both sections.
        This routine assumes one intersection only.
