Thanks Vincent, that’s high praise, was actually wanting to contribute one or two parts back as a change to titiler. It’s really not all that different than what you have but for changing the parameter(s) to floats. The quantizer bit would be left out of course as it would mostly be up to the client to make that decision.- Dr. Andrew AnnexOn Feb 13, 2023, at 1:06 PM, Vincent Sarago ***@***.***> wrote: @vincentsarago commented on this pull request.

note, with developmentseed/titiler#587 being merged the algorithm I added in this pr could be removed/simplified, I think. but merged it for now
