WMS isn't the way to go with this. I mean, it can do it, but the WMS
server may alter the values of the raster before serving them because
it's meant to serve maps, not data. The standard to use here is WCS -
Web Coverage Service. The WCS serves the four rasters as raw data so you
know when the user combines them client side they're using the real data.

Hi Geoserver user community,
We currently combine 4 rasters into 1 raster, based on weights
provided by the user through the browser in a UI. We now do this
in a complete custom way, running an R Shiny server, which uses
the leaflet client.
I would like to understand better what other possible
architectural patterns are, preferably in combination with
Geoserver WMS, in order to remain with open standards.
Are the following patterns valid, which one is best and am I
missing a pattern?
·Have a leaflet client, requesting 4 rasters from WMS, generating
a new raster (applying the weights) in the browser and displaying
this through leaflet?
·Make a custom WMS which takes the weights into account through
parameters and generates (applying the weights) the raster? Would
this custom WMS run in the Geoserver as some kind of plugin or
aside Geoserver as a separate webapp?
·Is a pattern with the Javascript library
https://github.com/GeoTIFF/geoblaze relevant here?
·Other?
Best,
Erik
