Gnuplot question: plotting 3D data in map view

I have a simple gnuplot question. I have a set of points (list of x,y,z values; irregularly spaced, i.e. no grid) that I want to plot. I want the plot to look like this: - map view (no 3D view) - color of each point should depend on z-value. - I want to define my own color scale - plot should...

GPIV_SSTRAIN(1) 					      General Commands Manual						   GPIV_SSTRAIN(1)

NAME

       gpiv_sstrain - Calculates the shear strain from PIV data.

SYNOPSIS

       gpiv_sstrain [-d N] [-h | --help] [--no_g ] [-p | --print] [-g | --g] [-v | --version] [filename] < stdin > stdout

DESCRIPTION

       gpiv_sstrain  calculates  the  shear strain from PIV data. You can choose from several differential schemes: central differentiation, least
       squares and Richardson extrapolation. The output can be generated as ASCII data containing four columns or  as  GNUPlot	Data  format  that
       allows one to view/print the data as contour plots.

       The configuration parameters (containing the POST key) may be overruled by the command line options, as explained below.

Options
       -d N   Differential  type  to  be  used:  central difference (N=0), least squares (N=1), Richardson interpolation (N=2), circulation method
	      (N=3)

       -h | --help
	      On-line help

       -p | --print
	      Print parameters, command line options and eventually used input and output filenames to stdout. The  output  is	identic  of  file-
	      name.par, in case filename is used.

       -g     Show contour plot of the output with gnuplot.

       --no_g Suppresses to show contour plot of the output with gnuplot.

       -v | --version
	      Print version information on standard output, then exit successfully.

       filename Input PIV data file. Overrides stdin and stdout. The
	      output  will be written to filename.sstr.  Parameters are stored in filename.par and may be used for future use by including them in
	      ./gpivrc.
