Currently you need to redo a calculation in order to change the result colormapping setting.

This is not so good in the case that the user only wants to experiment with the colormapping settings.

For best interactivity the colormapping procedure should be performed on the frontend. The result GeoTIFF data can be sent to the frontend and decoded using geotiff.js. See https://eox.at/2016/02/visualizing-raster-data/ for some prior art.
