How to Convert TER to JSON?

Take the guesswork out of TER to JSON conversion. Our step-by-step guide and robust tool give you fast, clean output from start to finish:

  1. 📥 Download and Install

    Download and install Autoconverter on your system. This application will let you to convert your TER files to JSON format - no additional CAD software required.

  2. 📂 Open Your TER File

    Go to File > Open to load your TER file (*.ter), or drag and drop it directly into the application window. The model loads into the 3D viewport for inspection before converting.

  3. 💾 Save As JSON Format

    Go to File > Save As, select JSON (*.json, *.cityjson) as the output format, choose your destination folder and filename, then click Save to complete the TER to JSON conversion.

TER TER File - Terragen Terrain Format

A TER file is the native terrain format for Terragen, a high-end landscape rendering and simulation tool. TER files store elevation data, procedural textures, and environmental settings to create realistic digital terrain models (DTMs) for visualization, animation, and VFX workflows.

Key Features of TER Files

  • Terrain Data: Encodes high-resolution elevation maps using 16-bit grayscale values for precise topography.
  • Multi-Texture Support: Includes diffuse, specular, bump, and displacement layers for natural surface rendering.
  • Procedural Nodes: Utilizes a non-destructive node-based system for flexible terrain editing in Terragen.
  • Landscape Fidelity: Ideal for creating mountainous landscapes, valleys, rivers, and erosion patterns in realistic detail.

TER File Conversion

Easily convert TER terrain files to 3D formats such as OBJ, STL, DAE, SKP, and STEP using Autoconverter and Automesher Application. These tools use the Open Asset Import Library to ensure reliable terrain data extraction, preserving elevation and surface information across 3D modeling, GIS, and CAD platforms. Export your Terragen landscapes and integrate them into your digital production pipeline today!

JSON 3D City Model (CityJSON) 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.
