domain - Domain/projection converter

SYNOPSIS

domain [parameters] [transform location]

PARAMETERS

Command Line	Resource	Default	Description
-h	help	No	Lists basic help information.
-df=filename	default	wxp.cfg	Sets the name of the resource file.
-me=level	message	out2	Specifies level of messages to be displayed
-fp=path	file_path	the current directory	Specifies location of database files.
-pd=domain	plot_domain	program dependent, mostly "us"	Sets the plotting domain
-pa=param[,param...]	parameter	none	Specifies addition parameters to program.
positional	transform	none	Specifies the transformation type: earth2proj -- transforms lat,lon to projection X,Y earth2grid -- transforms lat,lon to grid X,Y proj2earth -- transforms projection X,Y to lat,lon proj2grid -- transforms projection X,Y to grid X,Y grid2earth -- transforms grid X,Y to lat,lon grid2proj -- transforms grid X,Y to projection X,Y corners2proj -- output projection X,Y of each corner of domain corners2earth -- output lat,lon of each corner of domain
positional	point	none	Specifies the input location either as lat,lon or X,Y.

The domain program is an interface into the WXP domain/projection library. The user specifies a transformation and a location and the program transforms the data to the requested coordinates. The transformation is based on the resrc:plot_domain. Regions can also be specified.

EXAMPLES

```
domain -pd=us earth2proj 40,-90
6.755947,-55.022774
```
The input is the lat,lon coordinate 40,-90. South latitude and west longitude are negative. The output is the X,Y coordinates on the projection plane. In this case the projection plane is a polar stereographic projection centered on 97W longitude.
```
domain -pd=us earth2grid 40,-90
14.937368,7.268939
```
The output here is the location of the points relative to the grid specified by the plot domain. In this case, the grid is a 25x17 grid centered on 39,-97 with a grid spacing of 2.3 (230 km). The upper left hand gridpoint is 0,0 and the lower right gridpoint is 24,16.
