I want to compare elevation. Bare earth / mud elevation.
I want to know the difference in elevation.

The RasterExpressionEvaluator transformer can be used for this purpose. You will need to ensure that your datasets use the exact same extents. This can be accomplished using a combination of the BoundingBoxReplacer and the Clipper transformers. Here is an example that shows the procedure for a numeric (single band) dataset.
