<html><div style='background-color:'><DIV> <P>Hello, All</P> <P>Recently some one told me that Moving average is another good way for <BR>interpolation. But I have no idea about it. Does VisAD suppor it?</P> <P>For example, for an area of 10 by 10 m, I have some irregular points (with x, y, and z). <BR>Now I want to draw the surface using a grid with cell size of 1 m. First I have to interpolate<BR>these grid points to get the z values (this can be easily done using WEIGHTED_AVERAGE <BR>and NEAREST_NEIGHBOR methods in VisAD), then draw those grid points. Now I want to try the so called "Moving average" approach. The purpose is to get a smooth surface so that it is very close to the real topography visually.</P> <P>Any help will be highly apprecaited.</P> <P>Gaoming Fu </P> <P><BR> </P></DIV></div><br clear=all><hr>Chat with friends online, try MSN Messenger: <a href='http://go.msn.com/bql/hmtag1_etl_EN.asp'>Click Here</a><br></html>
