GeoJSON to CZML Converter

This Python script converts GeoJSON data containing geographic features with optional 3D model information into CZML (Cesium Markup Language) format. CZML is a JSON-based format commonly used for visualizing time-dynamic, geospatial data in the CesiumJS virtual globe.

Features

• Dynamic 3D Visualization: Convert GeoJSON data, including 3D model information, into CZML for dynamic and interactive 3D visualization.

• Real-World Scaling: Preserve the real-world dimensions of 3D models, ensuring accurate representation when zooming in or out.

• Distance-based Visibility: Control the visibility of models based on viewer distance, optimizing performance and preventing unnecessary rendering at large distances.

How to Use

1. Input GeoJSON: Provide a GeoJSON file with feature geometry and optional properties including unique identifiers, coordinates, and model URLs.

2. Run the Script: Execute the Python script, and it will generate a CZML file with the converted data.

3. Visualize in CesiumJS: Use the generated CZML file in a CesiumJS application for immersive 3D visualization.

Dependencies

• Python 3.x

Notes

• Ensure that the GeoJSON file follows the specified structure with feature properties, including 'Id', 'height', and 'model' (optional).

• Adjust the script parameters for model scaling, minimum pixel size, and distance-based visibility according to your preferences.

Example Usage

python geojson_to_czml.py # add input path before run
