Explode Geometry to Points — GeoJSON, Shapefile, KML and more
Extract every vertex of every feature as an individual point. Use these free browser-based tools to explode any vector dataset into its constituent coordinate points — useful for vertex analysis, coverage inspection, and point-based workflows.
What is exploding geometry to points?
Exploding geometry to points extracts every coordinate vertex from every feature in a dataset and returns each vertex as an individual Point feature. A line with 10 coordinates produces 10 points. A polygon with 50 ring vertices produces 50 points.
The output points inherit no geometry-specific properties but retain the original feature's attribute properties. This means you can trace back which original feature each vertex came from using the attribute table.
Exploding is particularly useful for checking vertex density, identifying data quality issues such as duplicate or very close vertices, and feeding coordinate data into point-based analysis workflows.
The operation runs entirely in your browser using Turf.js. No data is ever sent to a server.
Common use cases
Vertex density analysis
Check how many vertices a dataset contains and where they are concentrated — useful for identifying over-generalised or overly-detailed geometry.
Coverage inspection
Explode a polygon dataset to points to verify that all areas have adequate vertex coverage before generalisation or topology operations.
Point-based interpolation input
Convert polygon or line vertices to points for use as input to interpolation tools such as IDW or kriging.
Duplicate vertex detection
Explode a dataset and then inspect the point cloud for duplicate or near-duplicate coordinates that indicate geometry quality issues.
How to use
- 1
Upload your vector file (GeoJSON, Shapefile ZIP, KML, GeoPackage, or GML).
- 2
The file is parsed in your browser using GDAL WebAssembly and converted to GeoJSON.
- 3
Turf.js extracts every coordinate from every feature as an individual Point feature.
- 4
The resulting point cloud is converted back to your chosen format and downloaded.
Frequently asked questions
Does exploding work on point features?
Yes — a Point feature explodes to a single output point. The operation is valid but produces no change for point geometry.
Do output points inherit the original feature attributes?
Yes. Each output point retains the properties of the feature whose geometry it was extracted from.
Will polygon ring closure vertices be included?
Yes. Polygon rings are closed, so the first coordinate is repeated as the last. Both instances are included in the output, resulting in a duplicate point at the ring closure.
Can this produce very large outputs?
Yes — a dataset with complex geometry can produce many thousands of points. For large files, the output may be significantly larger than the input.
