I am looking for some tips about inserting a script in the ModelBuilder...
I am actually building a model in the ArcGIS ModelBuilder. At one point I would like to insert a script that crosses information from two layers at one point of the model with a output layer, that will be used further along.
In ArcMap, I added the script with a right-click in My Toolbox > Add Script...
After loading my script, I applied the following parameters:
- Two inputs, referring my layers that I use in the script (raster layer type)
- One output, for the result (raster layer type)
I then go to my model and drag my script into it. I connect my two layers as inputs with the arrow and specify the output file name. All seems ok as the boxes appear with the correct colors.
I have to specify that I am working with a variable folder %folder% so I added that in my script.
When I validate my model it goes all blank, because it cannot find the input layers, as they are created in the model.
Can anybody help me please?
PS: Here is my script:
