xm_station


NAME
     xm_station - Station format for the xmap8 program

SYNOPSIS
     xm_station - Input File Format

DESCRIPTION
     There are 4 different  station  file  formats  allowable  in
     xmap8.   Files are checked prior to importation, so the for-
     mats must be adhered to strictly.

     You can get point files loaded by using the -R  station_file
     option.

     If you use the -r station_file  symbol   each  station  file
     will be plotted with corresponding symbol.


FORMAT
     STATION file is organized on the UW format (university of Washington)

     Can have Several Station Files input. Use: -R file1 -R file2.....
     (R = Receiver)

     The default station format (the one I use for most of my work) is:
     Example:
     Name  lat.       long.      elevation(km)
     0...|....1....|....2....|....3....|....4....|..   (Card Column)
     S1V  36N00.7852 117W48.1522 1.197
     S1N  36N00.7852 117W48.1522 1.197
     S1E  36N00.7852 117W48.1522 1.197
     S2V  36N02.0210 117W47.3002 1.224

     However, the program can read station files in 3 other formats:
     These must be very RIGIDLY FORMATTED if xmap8 is to properly distinguish them.
     Xmap8 needs to see the fields in the correct card columns
     so that it determine the incoming format.
     Else all hell breaks loose.
     This is done so the user does not have to specify
     a format in advance, but the convention
     must be adhered to ridgidly!

     NOTE:
     You must insert an elevation.  Use 0 if you do not have one.

     Example follow:

     symbols for stations:

     0 = draw_triang = upside down triangle
     1 = draw_triang_2 = right side up triangle
     2 = draw_square = square
     3 = draw_star_david = star of david
     4 = draw_ex  =   X mark
     5 = draw_Plus =  + mark
     6 = draw_Diamond = diamond
