	This is a group of modules we used to plot the emission data for the
state of North Carolina.  This group of modules allows displaying points, lines
and polygons over a map of the United States. The group of the modules includes:

        AFSextract:             Extracting AFS Format Data
        AMSextract:             Extracting AMS Format Data
        LBFextract:             Extracting Link Base Mobile Data
        field_to_points:        Plot 3D points with color mapping
        field_to_lines:         Plot 3D lines with color mapping
        field_to_polygons:      Plot 3D polygons with color mapping
        getmap:                 Plot political boundary of states and
                                countys in the United State
        geomreset:              Reset and normalize the geometry viewer
                                automatically
        zoomer:                 A driver to allow zoom in and out to a
                                particular geographical area
        resetlegend:            To reset the position and size of ithe color
                                legend if used

	There are two modules in the package but are not listed here.  One is 
color_legend, another is draw_text.  They are both from AVS ftp site.  They
are in the package for network completion purpose.

	To test the modules, users may go to src directory and type "Make.all" 
to make all the executables.  Upon successful compilation, users may make a 
empty library and put all the modules into the it under AVS network editor.  
Then the users may pull out the example networks in the "networks" subdirectory.All the example map data are in GeoMAPS directory, while the test data are in
testdata directory.  Please be advised that the networks may crash if the users
do not set up the networks to met the configuration of their machines.
