Geoprocess - Raster calculator with Web Map Layers

[MinervaCenteno_Peña]

Hi ! 

I am trying to customize a widget in which it developes a raster calculator with a division of 2 raster bands. Those bands are part of the Web Map that I included in the app. I want to have a widget within I could select those bands thata are part of the base map layers, and then it will generate a new image.

It's possible ?

Thanks in advance !

I would recommend to look into GitHub - Esri/WAB-Image-Services-Widgets: Web AppBuilder widgets for Image Services (WABIS) code.

Thank you

Actually I just only would like to achieve how to establish an image server as an output parameter  in a geoprocess.

Thanks again!

Wouldn't it be easier to use raster functions: Overview of the Function Editor—ArcGIS Pro | ArcGIS Desktop ?
