How would i use the RasterBandMinMaxExtractor to get the absolute min and max of multiple rasters? i see it writes it back to the raster, but I should already have this value, i think. It shows with gdal. I'm trying to normalize multiple rasters for subtraction and am very new to FME.

Hi @csunderman1, I think you can use the StatisticsCalculator to calculate the minimum of the "min" values and the maximum of the "max" values. You can then merge the result unconditionally to each raster with the FeatureMerger (set an identical constant value - e.g. 1 to the Join On parameter for both Requestor and Supplier) if necessary.
Thank you @takashi I suppose i need to read more docs. i've been interested in using FME and the couple times i've tried to use it, i just never seem to accomplish anything.
