Edit GeoJSON visually, not by hand

Hand-editing GeoJSON coordinates in a text file is error-prone. Geisro lets you see and manipulate the geometry on a real map instead.

  1. Import - drag a .geojson file onto a layer, or paste features in.
  2. Edit - drag vertices and markers, draw new points, lines and polygons, and split work across coloured layers.
  3. Annotate - give each feature a name and custom attributes, and filter by name, attribute or value.
  4. Save - your features are stored in your account, ready to pick up and keep editing any time.

Does my GeoJSON leave my browser?
