Merci, Two follow up questions:
1) Is it possible to specify all bands within a multi-layered image? e.g., sum(imb*)? I ask because there are times that I wish to run a raster calculation involving a multi-layered image with 10s or 100s of layers (e.g., an image stack representing a time-series of temperature for every week, month, etc.). 2) Is it possible to calculate standard deviation, coefficient of variation, etc. using Band Math? Cheers!
