[Mapserver-users] Smoothing NEXRAD imagery

[Daryl Herzmann]

Hello all!

Well, I was playing around today with my various mapserver applications 
and have a question that I hope someone can answer.

I have been working on generating maps of current NEXRAD (Weather 
Service RARAR) imagery and overlaying observations.  This is currently 
working great, except the pixelation that occurs at very close range.  
Does anyone know how to implement an automatic TIFF smoothing algorithm at 
close ranges?

Here is a page with an example of what happens to the NEXRAD image at 
close ranges...  The pixelation at 25km is not that bad and will probably 
be what I live with for the final app.

The point in the center of these images is Ames, Iowa :)  We are 
experiencing freezing rain at the moment.

btw, in two weeks, the American Meteorological Society has its annual
meeting.  I will presenting the glories of mapserver at its first GIS
session of the IIPS (Information Processing) conference.  It should be
lots of fun promoting open-source!!

Thanks
  Daryl
