NAME

       PDL::Transform::Proj4 - PDL::Transform interface to the Proj4 projection library

SYNOPSIS

        # Using the generalized proj interface:
        # Make an orthographic map of Earth
        use PDL::Transform::Cartography;
        use PDL::Transform::Proj4;
        $a = earth_coast();
        $a = graticule(10,2)->glue(1,$a);
        $t = t_proj( proj_params => "+proj=ortho +ellps=WGS84 +lon_0=-90 +lat_0=40" );
        $w = pgwin(xs);
        $w->lines($t->apply($a)->clean_lines());

        # Using the aliased functions:
        # Make an orthographic map of Earth
        use PDL::Transform::Cartography;
        use PDL::Transform::Proj4;
        $a = earth_coast();
        $a = graticule(10,2)->glue(1,$a);
        $t = t_proj_ortho( ellps => 'WGS84', lon_0 => -90, lat_0 => 40 )
        $w = pgwin(xs);
        $w->lines($t->apply($a)->clean_lines());

DESCRIPTION

       Works like PDL::Transform::Cartography, but using the proj library in the background.

       Please see the proj library docs at <http://www.remotesensing.org/proj> for more
       information on proj, and how to use the library.

GENERALIZED INTERFACE

       The main object here is the PDL::Transform::Proj4 object, aliased to the t_proj()
       function.

       This object accepts all of the standard options described below, but mainly is there to be
       called with just the proj_params option defined.

       When options are used, they must be used with a '+' before them when placed in the
       proj_params string, but that is not required otherwise. See the SYNOPSIS above.

   ALIASED INTERFACE
       Other than t_proj(), all of the other transforms below have been autogenerated, and may
       not work properly. The main problem is determining the parameters a projection requires
       from the proj library itself.

       Due to the difficulties in doing this, there may be times when the proj docs specify a
       parameter for a projection that won't work using the anon-hash type specification. In that
       case, just throw that parameter in the proj_params string, and everything should work
       fine.

PARAMETERS AVAILABLE IN ALL PROJECTIONS

   General Parameters
       proj_params

       This is a string containing the proj "plus style" parameters. This would be similar to
       what you would put on the command line for the 'proj' tool. Like "+proj=ortho +ellps=WGS84
       +lon_0=-90 +lat_0=40".

       This parameter overrides the others below when it contains parameters that are also
       specified explicitly.

       proj

       The proj projection code to use (like ortho...)

       x_0

       Cartesian X offset for the output of the transformation

       y_0

       Cartesian Y offset for the output of the transformation

       lat_0

       Central latitude for the projection.  NOTE: This may mean other things depending on the
       projection selected, read the proj docs!

       lon_0

       Central longitude for the projection.  NOTE: This may mean other things depending on the
       projection selected, read the proj docs!

       units

       Cartesian units used for the output of the projection.  NOTE: Like most of the options
       here, this is likely useless in the current implementation of this library.

       init

       Specify a file:unit for proj to use for its runtime defaults. See the proj docs.

       no_defs

       Don't load any defaults. See the proj docs.

       over

       Normally, the transformation limits the output to between -180 and 180 degrees (or the
       cartesian equivalent), but with this option that behavior is turned off.

       geoc

       Input values are geocentric coordinates.

   Earth Figure Parameters
       ellps

       Ellipsoid datum to use. Ex: WGS72, WGS74.  See the proj docs and command line tool for
       list of possibilities ('proj -le').

       R

       Radius of the Earth.

       R_A

       Radius of a sphere with equivalent surface area of specified ellipse.

       R_V

       Radius of a sphere with equivalent volume of specified ellipse.

       R_a

       Arithmetic mean of the major and minor axis, Ra = (a + b)/2.

       R_g

       Geometric mean of the major and minor axis, Rg = (ab)1/2.

       R_h

       Harmonic mean of the major and minor axis, Rh = 2ab/(a + b).

       R_lat_a=phi

       Arithmetic mean of the principle radii at latitude phi.

       R_lat_g=phi

       Geometric mean of the principle radii at latitude phi.

       b

       Semiminor axis or polar radius

       f

       Flattening

       rf

       Reciprocal flattening, +rf=1/f

       e

       Eccentricity +e=e

       es

       Eccentricity squared +es=e2
