How it works
Uses Turf.js nearestPoint to find the closest point in your dataset to any query location using geodesic distance on a spherical Earth. Useful for nearest facility analysis, spatial joins, and proximity queries.
Powered by Turf.js and GDAL WebAssembly. All processing happens in your browser.
What is the Nearest Point Finder?
The Nearest Point Finder uploads a point dataset and interactively identifies which point is closest to any location you click on the map or specify by coordinate. The tool displays the distance, feature properties, and a connecting line between the query location and the nearest point.
Distance is computed using geodesic (great-circle) mathematics — the same method used in GPS calculations — giving accurate results regardless of geographic scale. The tool processes all points client-side in the browser using Turf.js; no data is sent to a server.
Common use cases
Nearest facility queries
Find the closest hospital, pharmacy, school, or other point-of-interest to any address or location.
Delivery and logistics routing
Determine which depot or collection point is nearest to a customer location for routing or allocation.
GPS track snapping
Snap a raw GPS location to the nearest point in a road network or trail dataset to clean up imprecise coordinates.
Emergency response
Quickly identify the nearest emergency resource (fire station, AED, emergency shelter) to an incident location.
Frequently asked questions
How is the nearest point distance calculated?
Distance is calculated using the geodesic (great-circle) formula, which accounts for the curvature of the Earth. This gives accurate results for points at any distance, from metres to thousands of kilometres.
Can I find the nearest point to a specific coordinate without clicking the map?
Yes — you can enter the query coordinates directly in the input fields instead of clicking on the map. This is useful when you have a known coordinate from a GPS device or database.
Does the tool work with line or polygon features?
The tool is designed for point datasets. For line or polygon features, upload a GeoJSON point layer derived from centroids or vertex extractions. Use the Centroid Tools on this site to convert polygons to centroid points first.
Can I download the result?
Yes — the nearest point feature and the connecting line to the query location can be downloaded as GeoJSON or KML for use in a GIS or web map.
