For example, in a site-selection analysis, you need the data values for the input rasters to be scaled from 0 to 100. This can be done by navigating to Processing Toolbox | GRASS commands | Raster | r.rescale tool. In the following example, the RiparianSurface.img raster with values ranging from 10 to 95.5 will be rescaled to a raster with values ranging from 0 to 100. To do this, perform the following steps:
