Spatial Trade Area
Description
Section titled “Description”The Spatial Trade Area step builds a trade area — one or more concentric buffers, sized in real-world units — around each geometry. It is the equivalent of the Alteryx Trade Area tool’s fixed-radius mode and runs in the workflow engine.
Source & Options
Section titled “Source & Options”- Source Table / Output Table — the input geometries and where the result is written.
- Geometry column — the WKT geometry column to build around.
- Radii — a single radius, or comma-separated concentric radii (e.g.
5,10,25). - Units — the real-world unit the radii are expressed in (miles, km, meters, feet).
- Output column — the name of the output geometry column.
Columns
Section titled “Columns”The Columns tab maps the input columns to pass through onto the output.
The radii are converted from the chosen real-world unit to an approximate degree radius before buffering (a planar approximation), so a ground circle reads as a mild ellipse far from the equator.
