I tried to convert a (segmented) three band raster into a polygon feature class using "Raster to Polygon". The tool successfully finished, but not all segment borders are represented in the output polygon feature class (red lines) (see attached image).
I found out that the tool only considers the values of the first band when drawing the polygons and therefore not all segment borders are represented in the vector data.
It would be good if the online help would outline that fact so that users are not confused when using this "Raster to Polygon" with an multiband raster. It also would be good if the option to consider multiple bands when processing the tool would be integrated.
