What GeoJSON Map Viewer does

View GeoJSON points, lines, polygons, bounds, and properties locally.

How to use GeoJSON Map Viewer

  1. Paste or upload GeoJSON.
  2. Load it on the map.
  3. Inspect features or download formatted data.

Method and calculation

GeoJSON is parsed and validated locally, then passed to Leaflet for display. The map fits to valid data bounds.

Privacy and external map tiles

Calculations and uploaded files remain in your browser. Visual map tiles are downloaded from the displayed map provider and are not hosted by Toolare. The page is therefore not fully offline.

Limitations

Files are capped at 5 MB and 10,000 features. Very complex geometry can still be slow on mobile devices.
