I'm using the Graphic Modeler/Processing Modeler to automate a process. The last step in this process is Merging three different Raster Layers. I'm using the "Merge Raster Layers" from Saga 2.0.8. Is if it is possible to specify the order in which these are merged?
I would like it in this order.
-#1 WaterStreams - Top
-#2 Grid with WaterStreams area (Watershed?)- Middle
-#3 Height Model (DEM) - Bottom
So #3 should be at the bottom, then #2 will be added on top of this and then #3 will be added at the top.
Pretty much a DEM with WaterShed burned into it, with WaterStreams burned through the DEM and WaterShed. If this makes sense?
If I do it manually and use the toolbox and Merge Raster Layers it's no problem (First value in grid order), but in the automated process I can't specify the correct order.
Update1::Tried editing the .model file, rearranging the order of #1, #2, #3, but no luck, either I'm not doing it right, or it doesn't work that way.
Update2:Tried a few more things using textpad editing, also tried doing two different "Merge Raster Layer" after each other, but no luck. It always puts #3 at the top, though I need it to be at the bottom.
