Hello List: Not sure if I asked this prior but does anyone know the syntax to apply a 3x3 filter within a formula. I have small areas within a height .ERS file that I would like to define a region around and apply the filter, smoothing these anomalies out. Something like "if (inregion(r1)) then filter else i1". I don't want to cut the region out, filter it and reapply it to the original file. This causes an edge to show when I put the region cut-out back in.
As usual any input is appreciated. Greg Reinecke GDM ----------------------------------------------------------- To make changes to your subscription, please visit our website, http://www.ermapper.com/technicl/ermapperl/index.htm
