GeoJSON

GeoJSON is a standard format for encoding geographic data in JSON. It's widely used in web mapping and is the internal format used by MapEdit.

1. Open the Import/Export panel
2. Click the Import tab
3. Drag and drop your .geojson or .json file
4. Features are automatically added to a new layer

• Point — Single locations
• MultiPoint — Multiple related points
• LineString — Paths and routes
• MultiLineString — Multiple related lines
• Polygon — Areas with optional holes
• MultiPolygon — Multiple related polygons
• GeometryCollection — Mixed geometry types

GeoJSON features can have arbitrary properties. MapEdit preserves these properties and uses them for:

• Feature names (from "name" property)
• Feature descriptions (from "description" property)
• Data-driven styling (classify by any property)
• Style detection — SimpleStyle-spec properties (fill, stroke, marker-color) are automatically applied as feature styles on import
• Export back to GeoJSON

1. Open the Import/Export panel
2. Click the Export tab
3. Select the layers you want to export
4. Choose "GeoJSON" as the format
5. Click Export

When exporting to GeoJSON, MapEdit includes:

• All geometry coordinates
• Feature name and description
• All custom properties
• Style properties (fillColor, strokeColor, etc.)
• SimpleStyle-spec properties (fill, stroke, stroke-width, marker-color) for compatibility with GitHub, geojson.io, and Mapbox

• Web development — Load directly in Leaflet, Mapbox, MapLibre
• Data exchange — Share with developers and analysts
• Backup — Save a portable copy of your data
• Version control — Track changes in git
