I have layers containing polygons. The difference between the layers are the periods of the year about which the layers have information. So layer 1 is called Lawn_p1 and layer 2 is called Lawn_p2 (p stands for period) and so on. The layers contain the same fields. With model builder I want to combine all these layers into one shapefile and also add for every field p1 up to p10. This way for every polygon I can see all the information for every period in the same row.
As a first step I want to change the field names of each layer by adding the period to it: so for layer Lawn_p1 every field should get _p1 at the end. This should then be done for all the other layers as well. Then I should merge/join the layers.
Does anyone know how to do the first step with model builder for all the layers?
I guess I have to use iteration/for loops.
