Geometries Assembler — Build & Split KML Point, Line & Polygon
Free KML geometries tool for maps and Earth workflows: assemble Point + LineString + Polygon into a Workbench-style MultiGeometry KML, or disassemble existing MultiGeometry into separate lon,lat coordinate lists. Copy ready-to-open KML for Google Earth — ideal after Circle Generator, Merge, or Reader edits.
Key features
- Assemble: center point (lat,lon) + LineString/Polygon ring (lon,lat)
- Disassemble: extract every coordinates block from pasted KML
- Workbench-style MultiGeometry output in one Placemark
- Copy full KML or per-part coordinate lists
What Geometries Assembler does
Assemble mode builds a MultiGeometry placemark with a center Point, a LineString path, and a Polygon outer ring from your inputs — similar to Circle Generator’s structure. Disassemble mode splits any KML with coordinate blocks into numbered parts you can edit in Merge, Reverse, or Segment.
Why local SEO and map teams use it
Package a store pin, coverage path, and territory ring in one Earth-ready file, or pull rings apart for spreadsheet edits before reassembling after Merge LineStrings.
Styles vs geometry
This tool focuses on geometry XML. Add Style or StyleMap in Earth, or reuse Circle Generator styling when you need colored rings and icons.
How to use this tool (best practice)
1) Choose Assemble or Disassemble. 2) Paste coordinates or KML. 3) Run. 4) Copy output. Related: Reader extracts coords; Circle Generator builds full circles; Merge stitches paths.
Frequently asked questions
Is this Geometries Assembler free?
Yes. It is free on GBP Local Ranker’s KML Workbench at /free-tools/kml-workbench/geometries — no login required for basic use.
What is MultiGeometry?
A KML container that holds multiple geometries (Point, LineString, Polygon) inside one Placemark.
What does Assemble mode create?
A Point from lat,lon, a LineString from lon,lat pairs, and a Polygon outer ring from the same line coordinates — Workbench-style output.
Can I assemble only a line?
This UI builds Point + LineString + Polygon together. For a single geometry, use lineStringKml-style tools or paste partial KML manually.
Will polygons fill in Google Earth?
Polygon XML is included; fill and stroke depend on PolyStyle in the viewer or styles you add afterward.
What does Disassemble do?
It extracts every <coordinates> block from pasted KML and lists them as numbered parts with vertex counts.
Do I need Style blocks?
Not for geometry assembly. Add styles in Earth or copy StyleMap patterns from Circle Generator if needed.
What coordinate order is used?
Center point: lat, lon (human). LineString/Polygon lists: lon,lat pairs (KML order), space-separated.
How is this different from Circle Generator?
Circle Generator builds full 360-point rings from radius. Geometries Assembler combines custom point, path, and ring inputs you provide.
Where is the full KML Workbench suite?
