@takashi As you have probably worked out I'm fairly new to more than push button FME. This should be really simple and probably is but I want to expose a numeric raster band value and create an attribute from it so that when I covert the raster to polygons I have the value as an attribute of the polygons. I have tried using attribute creator but can't work out the syntax. This leads on to another probably basic and related question: I want to replace values in a raster based on ranges of numbers - eg 0-12 becomes 12 and more than 12 but less than 20 becomes 20, etc. I can string together multiple instances of RasterCellReplacer to approximate this but there must be a more efficient way using RasterExpressionEvaluator for example. Again my syntax to do this is lacking. Any resources for a self-taught FME'r on that front that start at the basics?
