Spatial Functions in Alteryx

Alteryx offers a range of different spatial analytics functions to perform more advanced spatial calculations. They are as follows:

Buffer: this tool takes any polygon or polyline spatial object and expands or contracts its extents, effectively creating a zone around the spatial object

Create Points: creates a point-type spatial object using latitude and longitude (it is important to ensure that the coordinates are numbers)

Distance: helps to calculate distances between spatial objects

Find Nearest: identifies the shortest distance between spatial objects in one file and the objects in a second file

Generalize: decreases the number of nodes that make up a polygon or polyline, this has the effect of smoothing any edges

Heat Map: uses individual records to generate polygons representing heat levels in an area

Make Grid: this tool takes a specified spatial object and creates a grid based on the spatial object

Poly-Build: this tool uses spatial point objects to draw polygons or polylines in a specific sort order

Poly-Split: this tool splits polygon or polyline objects into their component point, line, or region objects

Smooth: a smoothing algorithm to round off the sharp angles of polygon or polyline objects

Spatial Info: this tool extracts tabular information about the spatial object

Spatial Match: establishes the spatial relationship between two sets of spatial objects

Spatial Process: performs high-level spatial object editing from a simple, single tool

Trade Area: creates regions around specified point objects in the input file

The type of tool needed will entirely depend on what you are trying to achieve. You will almost certainly need other tools beyond the ones listed here, such as data cleaning and aggregate tools to achieve your desired outcome.
