Frequently Asked Questions
- What is GeoJSON?
- GeoJSON is an open standard format for representing geographic features — points, lines, and polygons — along with their properties. It's used in APIs, mapping software, and data analysis.
- Is my GeoJSON data private?
- Yes — all parsing and rendering happens entirely in your browser using the Leaflet.js library. Your data is never uploaded to any server.
- What geometry types are supported?
- All GeoJSON types: Point, MultiPoint, LineString, MultiLineString, Polygon, MultiPolygon, and GeometryCollection — as individual Feature objects or in a FeatureCollection.
- How do I inspect a feature's properties?
- Click any feature on the map. A panel will appear showing all the feature's properties as key-value pairs, with a button to copy them as JSON.
- Can I upload a .geojson file?
- Yes — drag and drop a .geojson or .json file onto the upload zone, or click to browse. The file is read locally in your browser.
- What do the colours mean?
- Orange-red circles are Points, blue lines are LineStrings, and green fills are Polygons. A legend below the map explains the colour coding.
