Hi,
You could try a "join attribute by location" followed by a "Aggregate"...

Dear list,
I am trying to find a solution for the following problem with the
model builder:
My model asks for two vector polygon layers that will be combined by
‘union’. The resulting layer gets a new field (field calculator) and
is evaluated by ‘Statistics by categories’ algorithm. The fields for
the categories are selected by the user when calling the model. Since
those fields are present in the two separate input layers, I have to
use two separate ‘Vector field’ inputs.
The problem arises when I try to combine those two input variables to
use them together for the ‘Statistics by categories’ algorithm. AFAICS
there is no function inside the model builder to achieve this, so I
suggest I have to export the model as a python script. There I found
that the call of the Statistics function gives the name of the
variable as a parameter and not the variable itself:
alg_params = {
'CATEGORIES_FIELD_NAME': parameters['fields'], ….
How can I combine my two lists (~like “parameters[‘fields’+’fields2’],
or is there a way to do this inside the model builder that I didn´t find?
Thanks in advance for help, kind regards
Simon Dietmann
