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