To continue getting familiar with ArcGIS Pro, in this article we will discuss how the Model Builder is introduced in the new interface.
We will consider an example quite simple: With the INSEE (200m) statistical rectangles data, we will create buffer zones around a site every 500m. Basic data is presented as follows:
The star indicates the site location, the squares correspond to the population Insee ( downloadable on the INSEE website ) data.
Where can you find Model Builder? You will find the Model Builder button in the ANALYSIS tab of the ribbon :
The ribbon changes to show Model Builder’s control buttons and a new view is added : Model
From here , you will work quite similarly as you have, already, done with ArcMap.
How to create the model In the geoprocessing window , click-move the chosen tool , towards the Model view.
To add a data source , as always you will click and drag the data source of the legend window to the model window.
What changes: how to connect the model elements
Compared to the ArcMap Model Builder , where you
have
a Selection tool and a Connection tool, here you
have
a single SELECT button.
If
you click and release on an item, you select it.
If
you click and move the mouse to
another item, you connect them.
How to add an iterator To add the iterator that will allow us to calculate the different buffer sizes , click the Iterators button on the ribbon . Select the FOR iterator .
Double click to open the FOR setting window:
Once filled and closed , the iterator depicts a colour , so it is ready for use .
By clicking and dragging VALUE to the Buffer tool , the login window opens . Select “Distance” to indicate that it is this parameter that will be provided by the For Loop. The model is almost ready. It remains to modify the output name of the Buffer command file so that each iteration produces a separated file.
We use the online replacement variable: In the output file name we add VALUE surrounded by characters ‘%’. When running the model , this chain is replaced by the current value of VALUE.
How to execute the model To run the model just click on the RUN button tape. A tracking window opens :
How to save the
model
This is easier than when
using ArcMap. Each
ArcGis
Pro project has a default toolbox vacuum.
If
you click SAVE in the ribbon , your model
is
saved
directly
in
this
toolbox.
If
you want to save in
a
specific Toolkit , click SAVE AS
Point to the desired box. Lastly, we click on the MAP view and load the layers produced by the model:
