Spatial Poly-Build
Description
Section titled “Description”The Spatial Poly-Build step builds a polygon (or convex hull) per group from point geometries. It is the equivalent of the Alteryx Poly-Build tool and runs in the workflow engine.
Source & Options
Section titled “Source & Options”- Source Table / Output Table — the input points and where the result is written.
- Point geometry — the WKT point geometry column to build from.
- Group by — an optional column that groups the points into separate output polygons; leave blank to build a single polygon from all points.
- Build type — Sequence dissolves the grouped points into a polygon; Convex hull builds the convex hull of the points.
- 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.
