Alteryx has a Spatial only tab on it's interface. But why should you stick to it if there are other tools which can manipulate spatial data too?
For example the summarise tool. You may know at as a handy thing to group your data and calculate the sum, average etc. But you can also use it for example to combine spatial objects to one.
Imagine you have a dataset which contains every state of the US as a polygon. Very cool, but what do you do if you want a polygon of the whole US? Right! Take the summarise tool and combine these polygons!
Take your spatial objects, click "add", go to spatial and combine the polygons.
As you can see, there are more options in the menu, so let's cover these too. The "Create Intersection" option allows you to get the intersection between multiple polygons. The difference is, that every polygon is in the same column. If they are in different columns you need the intersection tool.
The third option is to "Create Bounding Rect". This takes the the outermost points and build a rectangle around them.
The fourth options is to "Create Convex Hull". This one is not as strict as the rectangle tool and builds a polygon around the outermost points.
Last but not least: the "Create Centroid". Useful if you have on object and you want to calculate the distance from the centre to other points. It calculates the centroid of a group of polygons and returns this point.
So - don't underestimate this tool, it can be pretty useful if you have multiple polygons stored in one column!
