UTM coordinates from lat/lon

Converts latitude-longitude coordinates into UTM (Universal Transverse Mercator).

The tool operates on trace headers or database tables. Sometimes the input data sets are tool large to manipulate them as tables efficiently. In such cases, FILE option allows processing one or several files. For each input file named, e.g.,'coords.latlon', a new file name will be created by appending '.xy': 'coords.latlon.xy'.

Along with the coordinates, the program will copy into the output file up to 10 numbers following them in each line.

A note on UTM zone nomenclature.

UTM zones (notation also used in this tool) are denoted using an integer zone number (corresponding to a 6-degree longitude range) followed by an upper-case character indicating an 8-degree latitude range. Longitude numbering starts from longitude 180W, and increases to 60 at 180E. Latitude ranges are represented as follows (South to North):

• C : -80 to -72 degrees;
• D : -72 to -64 degrees;
• E : -64 to -56 degrees;
• F : -56 to -48 degrees;
• G : -48 to -40 degrees;
• H : -40 to -32 degrees;
• J : -32 to -24 degrees;
• K : -24 to -16 degrees;
• L : -16 to -8 degrees;
• M : -8 to 0 degrees;
• N : 0 to 8 degrees;
• P : 8 to 16 degrees;
• Q : 16 to 24 degrees;
• R : 24 to 32 degrees;
• S : 32 to 40 degrees;
• T : 40 to 48 degrees;
• U : 48 to 56 degrees;
• V : 56 to 64 degrees;
• W : 64 to 72 degrees;
• X : 72 to 80 degrees;

(Note that letters 'I" and 'O' are skipped in this alphabetic sequence.)

For example, Saskatchewan is located in zone 13U.

Description of global parameter(s):

"Global" parameters describe the formats of trace headers used to input/output the values of trace coordinates

1 group of 5 REPEAT parameters per line:

"Repeat" parameters describe the formats of tables that can be processed in the same manner as the traces.
