Centroid Center Point
Find the geographic centroid (center of mass) of any GeoJSON polygon or feature collection.
About this tool
The PixelForge Centroid Generator finds the geographic centre point of any GeoJSON polygon or multipolygon and returns it as a GeoJSON Point feature with latitude and longitude coordinates. Centroids are used in labelling map features, calculating distances between areas, spatial joins, and data visualisation. Paste your GeoJSON, click Generate, and copy the centroid coordinates or full GeoJSON output in one step.
Frequently Asked Questions
A centroid is the geometric centre of a shape — the average position of all points within the polygon. It is used as a representative point for area features in maps and spatial analysis.
For convex polygons, yes. For concave or U-shaped polygons, the geometric centroid may fall outside the polygon boundary. For those cases, you may prefer a 'pole of inaccessibility' calculation instead.
Polygon and MultiPolygon features and FeatureCollections are supported. For a FeatureCollection, a centroid is calculated for each polygon feature.
Yes. Paste a GeoJSON FeatureCollection containing multiple polygons and the tool will return a FeatureCollection of centroid points.
The centroid is calculated using Turf.js which works with geographic coordinates and gives accurate results for typical GIS use cases.
