CityJSON (3D City Model) File
The CityJSON file format is a modern, JSON-based (JavaScript Object Notation) standard designed for storing and exchanging 3D city models. It efficiently encodes buildings, roads, bridges, urban furniture, and other city objects, offering strong support for textures, semantics, and detailed metadata. CityJSON is a lightweight alternative to CityGML, optimized for simplicity, web integration, and high-performance applications.
Key Features of CityJSON Files
- JSON Simplicity: CityJSON files are lightweight, human-readable, and easily parsed by common programming languages, avoiding the complexity of XML structures like in CityGML.
- Semantic Data: Preserves rich metadata, including building heights, roof shapes, material classifications, and road types, enhancing 3D GIS and urban analysis.
- LOD (Level of Detail) Support: Manages multiple levels of detail (LOD1 through LOD4) to suit diverse visualization, simulation, and analysis needs.
- Web-Friendly Format: Perfect for 3D web visualization and integration with JavaScript libraries like Cesium and Three.js.
- Open and Extensible: Developed by the 3D Geoinformation Group (Delft University of Technology), CityJSON is an open standard that promotes interoperability and innovation.
- File Extension Note: Both CityJSON and GeoJSON use the .json extension - ensure you verify the file structure before processing to avoid errors.
CityJSON File Conversion Made Easy
With Autoconverter and Automesher Application, you can seamlessly import, export, and convert CityJSON files into formats like STL, OBJ, SKP (SketchUp), and 3DS. Our tools preserve geometric precision and semantic information, making it easy to integrate 3D city models into your CAD, GIS, and 3D visualization workflows.

DAE File Format (COLLADA) - 3D Model Exchange Standard
DAE (Digital Asset Exchange) is a widely supported, XML-based 3D file format designed for seamless interoperability between digital content creation tools. Developed by Sony and maintained by the Khronos Group, the COLLADA standard enables the efficient exchange of complex 3D assets - including mesh geometries, materials, skeletons, and animation data—across different software platforms.
Key Features of DAE/COLLADA Files
- Reusable Geometry: Enables multiple objects to reference the same geometry instance, minimizing file size and improving performance.
- Multi-Texture Support: Supports advanced material properties with multiple texture images and coordinate sets for each mesh face.
- Opacity and Object Grouping: Allows control over transparency and organizes objects into named groups for easier scene editing and manipulation.
Convert DAE Files to Other 3D Formats
With Autoconverter and Autoshaper, you can accurately convert DAE (COLLADA) files to other popular 3D formats such as STL, OBJ, SKP, DWG, 3MF, and more. These tools use the open-source OpenCOLLADA framework to ensure full support for both COLLADA 1.4 and 1.5 specifications. Preserve animations, materials, and scene hierarchy with reliable conversion powered by OpenCOLLADA.
Streamline your 3D pipeline with powerful DAE file conversion tools - ideal for game developers, animators, and CAD professionals working across platforms.
