xm_points

NAME
     xm_points - Points format for the xmap8 program

SYNOPSIS
     xm_points - Input File Format

DESCRIPTION
     This is for providing plotting of points where  the  control
     of the symbol, label size and fonts as desired.  This facil-
     ity is useful if you  have  cities,  highways,  volcanos  or
     other point objects that need to be identified, but that are
     not conveniently plotted as earthquakes.

     You can get point files loaded by using  the  -p  point_file
     option


FORMAT
     Files are free format with this input:
     name lat lon depth color symbol symcode symsize strcode font_size just


     where,
     name = alpha numeric label, up to 200 characters, uses underscore '_' for spaces
     lat  = latitude, positive north
     lon = longitude, positive east
     depth = depth in km, positive down!
     color = color index drawn from the standard xmap8 palatte (see manpage xm_color)
     symbol = symbol code: one of
          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
          7 = draw_Circle= empty circle
          8 = draw_Fill_Circle = filled circle
          9 = draw_asterix = asterix
     symcode = 0->off  1->plot symbol
     symsize = size of symbol in pixels
     strcode = plotting label 0->off  1->plot symbol
     font_size  = font size in points(72=inch), for the screen
                 there are only 2 sizes (>12 or <12)  for the postscript
                 though, this will be the true size in points
     just =  0 ->left justify
             1 -> centered
             2 -> right justify
