The latest version of GdalGrid (in FWTools) seems to not use the radius
values properly for the Nearest algorithm. In my project, I used 4000 for
both but I ended up with very little circles around the data points. Using
the same radius values for the Inverse Distance algorithm produced values
for the entire display (which is what I would expect because my entire
project is 4000x4000).
