Spatial Buffer
Description
Section titled “Description”The Spatial Buffer step grows each geometry in a column by a fixed distance, writing the buffered geometry to an output column. It is the equivalent of the Alteryx Buffer tool, and runs in the workflow engine (the geometry work is not expressible in SQL).
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 buffer.
- Buffer distance — how far to grow each geometry, in the geometry’s own coordinate units.
Columns
Section titled “Columns”The Columns tab maps the input columns to pass through onto the output; the buffered geometry column is appended automatically.
