🔄 Convert KML to JSON: Google Earth Map to CityJSON Model Conversion

How to Convert KML to JSON❓

Whether you're new to KML to JSON conversion or a seasoned professional, our step-by-step guide and reliable tool make the process effortless:

  1. 📥 Download and Install

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

  2. 📂 Open Your KML Map

    Go to File > Open… to load your KML map (*.kml), 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 KML to JSON conversion.

KML Keyhole Markup Language (KML) File

The Keyhole Markup Language (KML) file format, originally created by Keyhole, Inc. (later acquired by Google), is a widely used standard for storing and sharing geospatial information. KML files are essential for visualizing geographic data in applications like Google Earth, Google Earth Pro, ArcGIS, QGIS, and other mapping platforms.

Main Features of KML Files

  • XML-Based Format: KML files use an easy-to-edit XML structure to define geographic features such as points, paths, polygons, and 3D models for interactive mapping projects.
  • Broad Compatibility: KML files are fully supported across popular GIS and CAD applications, enabling seamless data sharing, visualization, and analysis across multiple platforms.
  • Rich Media Support: Embed images, videos, links, and other multimedia elements inside KML placemarks and descriptions to create dynamic and informative maps.

KML File Conversion and Integration

Convert and manage KML files effortlessly with our Automapki Application. Easily transform your AutoCAD, BricsCAD, and ZWCAD DWG entities - including points, polygons, curves, meshes, and 3D solids - into high-quality KML files. You can also import KML data back into your DWG drawings with full precision and control.

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.
