ConicProj -- perform conic projections

ConicProj was written by Charles Karney.

       Perform one of two conic projections geodesics.  Convert geodetic coordinates to either Lambert conformal
       conic or Albers equal area coordinates.  The standard latitudes lat1 and lat2 are specified by that the
       -c option (for Lambert conformal conic) or the -a option (for Albers equal area).  At least one of these
       options must be given (the last one given is used).  Specify lat1 = lat2, to obtain the case with a
       single standard parallel.  The central meridian is given by lon0.  The longitude of origin is given by
       the latitude of minimum (azimuthal) scale for Lambert conformal conic (Albers equal area).  The
       (azimuthal) scale on the standard parallels is k1.

       Geodetic coordinates are provided on standard input as a set of lines containing (blank separated)
       latitude and longitude (decimal degrees or degrees, minutes, seconds);  for details on the allowed
       formats for latitude and longitude, see the "GEOGRAPHIC COORDINATES" section of GeoConvert(1).  For each
       set of geodetic coordinates, the corresponding projected easting, x, and northing, y, (meters) are
       printed on standard output together with the meridian convergence gamma (degrees) and (azimuthal) scale
       k.  For Albers equal area, the radial scale is 1/k.  The meridian convergence is the bearing of the y
       axis measured clockwise from true north.

       Special cases of the Lambert conformal projection are the Mercator projection (the standard latitudes
       equal and opposite) and the polar stereographic projection (both standard latitudes correspond to the
       same pole).  Special cases of the Albers equal area projection are the cylindrical equal area projection
       (the standard latitudes equal and opposite), the Lambert azimuthal equal area projection (both standard
       latitude corresponds to the same pole), and the Lambert equal area conic projection (one standard
       parallel is at a pole).

       An illegal line of input will print an error message to  standard  output  beginning  with  "ERROR:"  and
       causes  ConicProj  to return an exit code of 1.  However, an error does not cause ConicProj to terminate;
       following lines will be converted.

          echo 39.95N 75.17W | ConicProj -c 40d58 39d56 -l 77d45W
          => 220445 -52372 1.67 1.0
          echo 220445 -52372 | ConicProj -c 40d58 39d56 -l 77d45W -r
          => 39.95 -75.17 1.67 1.0

ConicProj was added to GeographicLib, <https://geographiclib.sourceforge.io>, in version 1.9.

       ConicProj -- perform conic projections

-clat1lat2
           use the Lambert conformal conic projection with standard parallels lat1 and lat2.

       -alat1lat2
           use the Albers equal area projection with standard parallels lat1 and lat2.

       -llon0
           specify the longitude of origin lon0 (degrees, default 0).

       -kk1
           specify the (azimuthal) scale k1 on the standard parallels (default 1).

       -r  perform the reverse projection.  x and y are given on standard input and each line of standard output
           gives latitude, longitude, gamma, and k.

       -eaf
           specify the ellipsoid via the equatorial radius, a and the flattening, f.  Setting f = 0 results in a
           sphere.   Specify  f  < 0 for a prolate ellipsoid.  A simple fraction, e.g., 1/297, is allowed for f.
           By default, the WGS84 ellipsoid is used, a = 6378137 m, f = 1/298.257223563.

       -w  toggle the longitude first flag (it starts off); if the  flag  is  on,  then  on  input  and  output,
           longitude  precedes  latitude  (except  that,  on  input,  this  can  be  overridden  by a hemisphere
           designator, N, S, E, W).

       -pprec
           set the output precision to prec (default 6).  prec is the number of digits after the  decimal  point
           for  lengths  (in meters).  For latitudes and longitudes (in degrees), the number of digits after the
           decimal point is prec + 5.  For the convergence (in degrees) and scale, the number  of  digits  after
           the decimal point is prec + 6.

       --comment-delimitercommentdelim
           set  the  comment  delimiter  to  commentdelim  (e.g., "#" or "//").  If set, the input lines will be
           scanned for this delimiter and, if found, the delimiter and the rest of  the  line  will  be  removed
           prior to processing and subsequently appended to the output line (separated by a space).

       --version
           print version and exit.

       -h  print usage and exit.

       --help
           print full documentation and exit.

       --input-fileinfile
           read  input  from  the  file  infile  instead  of  from standard input; a file name of "-" stands for
           standard input.

       --input-stringinstring
           read input from the string instring instead of from standard input.   All  occurrences  of  the  line
           separator character (default is a semicolon) in instring are converted to newlines before the reading
           begins.

       --line-separatorlinesep
           set the line separator character to linesep.  By default this is a semicolon.

       --output-fileoutfile
           write  output  to  the  file  outfile  instead  of  to standard output; a file name of "-" stands for
           standard output.
