****** USERS INSTRUCTIONS ******
The program will compute a either projection
The standard ellipsoid for the UTM projection is
A series of central meridians are defined in 6 degree zones starting at 180 degrees west.
The user may choose this standard projection or may choose a 3 degree as defined for Canada. The scale facter for this projection is .9999 and the false easting is 3048000.0 meters
The user may define any other combination of UTM projection by changing the definitions of scale, central meridian, false easting and false northing.
Coordinates may be entered from the terminal for conversion or from a file. The results can be saved in a formatted listing or on a coordinate file.
The coordinates are defined by records as follows
Column 7-31 contain the STATION NAME AND NUMBER Column 40-42 contain the DEGREE PART OF the LATITUDE (USE NEGATIVE SIGN FOR SOUTH LATITUDES). Column 44-45 contain the MINUTE part OF the LATITUDE. Column 47-54 contain the SECONDS part of the LATITUDE. Column 56-58 contain the degree part the LONGITUDE (positive WEST of GREENWICH) Column 60-61 contain the MINUTE part of the LONGITUDE Column 63-70 contain the SECONDS part of the LONGITUDE
Column 8-31 contain the STATION NUMBER and NAME Column 51-52 contain the UTM ZONE NUMBER. Column 57-68 contain the EASTING Column 69-80 contain the NORTHING (FOR SOUTH LATITUDES, the FALSE NORTHING IS 10,000,000 METRES AND the RE MUST BE A NEGATIVE SIGN PRECEDING the NORTHING VALUE FOR USE AS A FLAG INDICATING SOUTH LATITUDE IN the PROGRAM).
****** OUTPUT ******
the formatted output of program GSRUG will consist of the following
The job title at the top of a new page along with either
A sequential listing of the input coordinates in turn followed immediately by the appropriate transformed value. For the UTM values, the zone number is listed first followed by the easting and northing. When scale factors are desired in the Geographic to UTM mode, they will be listed to the right of the northing.

Notes --
The user may choose to define their own projection by defining a Central meridian, false easting, false northing and/or scale factor. To force a zone the user would choose a projection defined by the Central meridian of the forcing zone.
