GeoJSON Bounds Calculator

Inspect bounded GeoJSON without uploading it. Get conventional bounds, a compact antimeridian-aware interval, geometry counts, and a vertex-weighted centroid.

Maximum 2 MB, 10,000 features, 500,000 positions. Longitude/latitude must be finite; out-of-range positions are warned and excluded.

Warnings

  • Calculate to inspect the document.

Preview is schematic and uses no basemap or network. Centroid is the arithmetic mean of valid positions, not an area centroid.
