I have a raster with text descriptions of vegetative classes that I wish to place on some points. I know the band and palette where the description resides (band 0, palette 2), which I have exposed using the RasterSelector. I can see the values correctly output in the Feature Information window of an Inspector but not in the Table View window of the Inspector. In other words, I can't find how to expose the values (text descriptions) as attributes. I've tried the ListExploder, ListIndexer, RasterPaletteExtractor, and Format Attributes of the Reader. I can see _band{}.palette{}.value listed as an attribute in the PointOnRasterValueExtractor so it seems all I need to do is expose _band{0}.palette{2}.value. The question is how? Hoping someone can point me in the right direction.

Thanks,

Aaron

You can use an attributecreator (or an attribute manager) to create a new attribute with the value set to the value in the list
