I am trying to create an interactive online map that allows users to toggle the weights of risks and mitigating factors in a riparian assessment project.

We are using ArcGIS Experience Builder, but the suitability model widget cannot handle negative raster values, which are essential for this model to function.

Rescaling values to be all positive numbers will not work, because an area where a risk factor and a mitigating factor overlap would have higher value than areas where there is only a mitigating factor. The attached image illustrates the problem.

Our GIS team has no experienced in developing widgets, so we either need a pre-existing widget, a coding solution that a beginner could tackle, or we need some help from a widget developer.

Any ideas out there?

Thanks for your help!
