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.

PNG (Portable Network Graphics) File Format
The PNG (Portable Network Graphics) format is a popular raster image file type that uses lossless compression to maintain high image quality while reducing file size. Supporting full transparency and a broad color range, PNG files are widely used for web graphics, logos, icons, and images requiring crisp, clear details. Unlike GIFs, PNG does not support animation but offers superior image clarity and flexibility.
Key Features of PNG Files
- Efficient Lossless Compression: PNG files compress data without losing quality, using the DEFLATE algorithm for smaller, faster-loading images.
- Transparency and Alpha Channels: Supports 8-bit transparency, allowing for smooth blending and irregular image shapes ideal for web design and mobile apps.
- Superior Image Quality: Excels at preserving sharp edges, solid colors, and fine details, making it ideal for graphics, logos, and text overlays.
- Flexible Color Support: From 256-color palettes to 24-bit RGB with transparency, PNG adapts to a wide range of visual styles and file size requirements.
