Convert KML to SCN

Understanding KML and SCN file formats

KML (Keyhole Markup Language) is an XML-based file format used to display geographic data in mapping applications such as Google Earth and Google Maps. It stores geographic features like points, lines, polygons, and images with their coordinates and attributes.

SCN files are scene files used by various simulation and visualization software, such as Trainz Simulator or OpenSceneGraph. These files typically contain 3D scene descriptions, object placements, and sometimes terrain or environmental data.

How to convert KML to SCN

Direct conversion from KML to SCN is not commonly supported by most standard GIS or 3D modeling tools, as these formats serve different purposes. However, you can achieve this conversion through an intermediate step:

1. Convert the KML file to a more widely supported 3D format such as OBJ or DAE (Collada) using GIS software like QGIS or Global Mapper.
2. Import the resulting 3D file into a 3D modeling tool (e.g., Blender or 3ds Max), then export it to the SCN format if supported by your target application.
3. For Trainz Simulator, use the Trainz Content Creator Plus or Trainz Asset Creation Studio to import 3D models and create SCN scene files.

Recommended software for KML to SCN conversion

• QGIS: Open-source GIS software that can import KML and export to various 3D formats.
• Blender: Free 3D modeling tool that supports importing/exporting many 3D formats.
• Trainz Content Creator Plus: For creating SCN files for Trainz Simulator.

Typical workflow: QGIS: Layer → Export → Save Features As… → DAE/OBJ, then Blender: File → Import → DAE/OBJ, edit as needed, and finally export or use in your SCN-compatible application.

Important notes

• Check the specific requirements of your target application for SCN file compatibility.
• Manual adjustments may be necessary after conversion to ensure correct object placement and scene structure.
