xm_points


NAME

xm_points - Points format for the Geotouch 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 Geotouch palette (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


Example file:

Mt._Rainier 46.85 -121.76666 -3.9 1 3 1 25 1 14 1
Mt._St._Helens 46.18333 -122.18333 -2.0 1 3 1 25 1 14 1
Lake_Washington 47.619713 -122.237053 5.0 1 1 1 10 1 13 0
Test1 48.216595 -122.278008 0 1 4 0 10 1 11 1
Test2 46.689793 -123.019196 7.0 1 5 1 4 1 11 2



The choice of colors for points should be chosen from the color palette
described in:xm_color.
I should note that colors 60-100 are a rainbow palette
and colors 100-140 are blue-black-red palette
that can be used for scaling points to different color schemes.
A program for converting hypocenters (sources) to points
and scaling them by magnitude is provided in perl script "ac2pts_col.prl".
