Segment LineString — Divide Paths Into Equal-Length Segments
Free Segment LineString tool for KML and map workflows: paste lon,lat vertices, choose N segments, and split the path by equal geodesic length (not vertex count). Copy each segment’s coordinates for checkpoints, coverage spacing, or Merge LineStrings after edits.
Key features
- Paste LineString as space-separated lon,lat pairs
- Choose number of equal-length segments (N)
- Cuts by traveled meters along the polyline (Haversine)
- Copy each segment’s coordinate list separately
What Segment LineString does
It divides a polyline into N segments of equal geodesic length. Unlike splitting by vertex count, cuts are placed by distance traveled along edges — new points are interpolated where needed.
Why local SEO and map teams use it
Space rank-grid samples, checkpoint markers, or survey legs evenly along a route. Edit segments individually, then Merge LineStrings to recombine.
Equal length vs equal vertices
Vertex-based splits ignore real-world distance on curved paths. This tool uses Haversine meters per edge so each segment spans the same traveled length.
How to use this tool (best practice)
1) Paste lon,lat LineString. 2) Set segment count N. 3) Segment. 4) Copy each leg. Next: Merge LineStrings, Reverse, or Geometries Assembler.
Frequently asked questions
Is this Segment LineString tool free?
Yes. It is free on GBP Local Ranker’s KML Workbench at /free-tools/kml-workbench/segment-linestring — no login required for basic use.
What format should I paste?
Space-separated lon,lat pairs in KML order — for example: 78.3489,17.4401 78.36,17.45 78.37,17.44.
Does it move original vertices?
The overall shape is preserved; new cut points are interpolated along edges where segments divide.
What if N is very large?
Very short paths with huge N create tiny segments — keep N practical for your path length.
Does it work on closed rings?
Yes, but treat the ring as an open path. Close explicitly afterward if you need a polygon ring.
Does it output KML files?
Copy each segment’s coordinates into Geometries Assembler or wrap with LineString KML templates manually.
What units are used internally?
Haversine geodesic meters along each edge — the same basis as Distance Calculator.
How is this different from Merge LineStrings?
Segment divides one path into pieces. Merge joins two or more paths into one LineString.
Can I undo segmentation?
Use Merge LineStrings on the segment outputs in order to recombine (shared joints may collapse).
