All mapping products are informed by either importing raster.tif / misc.tif or raster math using raster.tif and/or misc.tif. 
raster.tif and misc.tif can be exported via REV_dataCreation and REV_analysis, respectively. Layers created using raster math -
e.g. change in Q/P, change in ET/P, etc. - are not provided and will need to be reproduced by the viewer.

Example raster math used-

Description:
Sbedrock(my) - Sbedrock(a): subtract Sbedrock(a) from Sbedrock(my), as derived from the raster.tif.

Raster calculator expression:
raster@8 - ((raster@5 >= 0) * (raster5))

Explanation:
Sbedrock(my) is held in band 8 of raster.tif and Sbedrock(a) is held in band 5 of raster.tif. The annual resetting deficit method
returns negative values if Ssoil > Sr and, therefore, we have to clip the values to zero by creating a mask where Sr > Ssoil and
multiplying by the value of raster. This effectively sets pixels where Ssoil > Sr to zero and returns Sr - Ssoil if Sr > Ssoil.
