NAME

m.proj - Calculates conversion coordinates for geographic positions.
(GRASS Map Development Program)

m.proj
m.proj help

This program allows a user to interactively: convert coordinates from one projection to another

It allows a user to do all of the above:: reading from a file, writing to the screen, or; reading from the keyboard, writing to a file, or; reading from a file, writing to a file,

Note: The program does not transform GRASS files, it is designed to determine coordinate values on an individual position.

The map projections currently supported are listed in etc/projections file

Each of the above projections (with the exception of State Plane) can be computed with the spheroids listed in etc/ellipse.table file

When reading from a file of LATITUDE/LONGITUDE data the file will contain three (2) columns of information:: the first column - latitude - in degrees minutes seconds,; the second column - longitude - in degrees minutes seconds,

For example:

	+40 36 31.4563	-87 2 7.8193	
	40n 36 31.4563	87w 2 7.8193

When reading from a file of PROJECTION COORDINATES data the file will contain three (2) columns of information:: the first column - easting - ground coordinates; the second column - northing - ground coordinates

For example:

 	 500000.00	4496918.64	
	-424489.11	1908736.13

Note: NO column headings are required, just the numbers.
