Thanks for the suggestion, we have tried enabling and disabling anti-aliasing and we don’t see an impact to the returned result.
We have looked into WCS but if we use that, it will prevent many of our clients from accessing the data since they only have the ability to add WMS layers to their tools.
Is the algorithm that takes the raw input and transforms it into the output we see documented somewhere? Or do we need to go through the source code to determine how it works? If we have to accept the loss of fidelity in the output we need to understand what is going on so we can explain it our clients.
Thanks again for all of your help.
