Hello,<br>
<br>
I tried to plot station data of surface temperature on a map as a
contour plot. I'm not satisfied with the result (see attached
picture AreaFill.png).<br>
It all seems so angular. My grid is not regular because of the
station data. <br>
<br>
Switching from AreaFill to RasterFill results in a litte better plot
(smooth contours) as you can see in the picture attached
(RasterFill.png).<br>
<b><font face="Courier New">res@cnFillMode = "AreaFill"<br>
res@cnFillMode = "RasterFill"</font></b><br>
<br>
I tried to regrid the triangular mesh (unstructured) station data to
a structured grid using <b>natgrid</b>?<br>
But it fails ...<br>
<br>
Do you have any ideas for a better plot? Or what is the correct way
to plot such station data as contour?<br>
<br>
Regards<br>
MeteoBB<br>
