Urban Eye 3D – JOSM 3D Viewer Plugin
Overview
Urban Eye 3D is a JOSM plugin that provides a dedicated 3D view (dockable or floating) to visualize loaded buildings and building parts (building=* and building:part=*). The main goal of the plugin is to make the creation and editing of 3D buildings in OpenStreetMap easier by allowing mappers to preview their edits directly within JOSM before uploading them to the server.
Key Features
- Support for the Simple 3D Buildings specification.
- Visualization only – no editing or export functionality.
- Intuitive navigation, similar to modern 3D editors.
- Basic color support for
building:colourandroof:colourtags. - Two display modes: solid and wireframe.
- Real-time updates: Changes made in JOSM instantly reflect in the 3D view.
How to Use
Navigation
- Orbit: Press and hold the left mouse button and drag the mouse.
- Zoom: Use the mouse wheel.
- Pan: Press and hold the right mouse button and drag the mouse.
Display Modes
The plugin supports two display modes:
- Solid: A view with filled polygons.
- Wireframe: A view that shows only the edges of the geometry.
To switch between modes, press the Z key. You can change this hotkey in JOSM hotkeys preferences.
Supported Roof Shapes (roof:shape)
See Plugin documentation for the list of supported roof shapes.
Limitations
- Several roof shapes (
mansard,half-hipped, andcross_gabled) are supported for quadrilateral polygons only. Support for those roof shapes on arbitrary non-convex polygons may be added in future versions.
