Thanks Jamie.
"Expand" tool looks like working well when applying Thematic raster data,
however, what I would like to have is expand an area on Multispectral
continuous raster data, satellite imagery, based on Euclid distance
for four neighbor or eight neighbor direction.
This function should be quite useful to generate boundary polygon of
distinctive area of multispectral data like water, single species forest,
and so on.
In fact, this function is contained on ERDAS Image Analysis for ArcGIS,
but I would like to populate it on "ESRI" ArcGIS due to the political,
competitive, reason.
Best regards.
