Visualize Large GeoJSON Datasets Online: From Upload to Interactive Map in Minutes
Handling 10MB+ GeoJSON? geojson.cloud visualizes it instantly on Google Maps — with clustering, heatmaps, and embeds — keeping everything client-side for speed and privacy.
Step-by-Step Visualization
- Upload & Load: Drag GeoJSON (or convert from Shapefile/CSV) — supports up to 50MB on Team plan ($29/mo).
- Style Layers: Toggle fills, strokes, labels; apply choropleths by property (e.g., population density). Cluster dense points to avoid clutter.
- Interact & Export: Zoom/pan with popups; generate embed code for Leaflet/OpenLayers or static PNG/SVG exports.
Handling Scale
- Performance: Quantizes coords on-the-fly for smooth rendering; no crashes on 100K+ features.
- Collaboration: Pro users share read-only links; API for devs to integrate into apps.
- Example: Urban planning datasets — visualize buffers around points, then edit/export for reports.
Free tier limits to 5MB; Pro unlocks unlimited for pro workflows.
