<P><SPAN LANG="en-ca"><FONT SIZE=2 FACE="Arial">Hi,</FONT></SPAN>
</P>
<P><SPAN LANG="en-ca"><FONT SIZE=2 FACE="Arial">I am trying to understand how the parameters of curvature, slope, etc. are calculated in r.resamp.rst:</FONT></SPAN>
</P>
<P><SPAN LANG="en-ca"><FONT SIZE=2 FACE="Arial">1) Does the code carry out the calculations on a *variable sized*, e.g. 3x3, 5x5, etc. (pixel-centered) array as mentioned in Mitasova (1993)? If so, this should be stated in the html help.</FONT></SPAN></P>
<P><SPAN LANG="en-ca"><FONT SIZE=2 FACE="Arial">2) What exactly is this "overlap parameter"?</FONT></SPAN>
<BR><SPAN LANG="en-ca"><FONT SIZE=2 FACE="Arial">3) The html help says nothing about range of values for the smoothing raster. I read somewhere they have to be greater than zero but some more information would be helpful.</FONT></SPAN></P>
<P><SPAN LANG="en-ca"><FONT SIZE=2 FACE="Arial">Aside from these issues, r.resamp.rast is extremely useful for my purposes!</FONT></SPAN>
</P>
<P><SPAN LANG="en-ca"><FONT SIZE=2 FACE="Arial">Thanks in advance for any answers,</FONT></SPAN>
