Hello,
I’m excited to introduce my new SketchUp extension OGI-IT SketchUp Tools.
The extension enables importing GeoJSON data into SketchUp and exporting SketchUp geometry back to GeoJSON.
Its main purpose is to make working with real-world terrain data in SketchUp easy and accessible.
With this workflow, you can collect terrain data using free and open-source GIS tools like QGIS and QField.
If you connect a GNSS antenna with RTK support, you can achieve centimeter-level precision—ideal for professional surveying.
However, you can also use the built-in GPS of your smartphone or tablet, which works out of the box with no additional hardware or cost (with lower accuracy, typically around a few meters).
Once imported, the terrain data is converted into a 3D mesh in SketchUp. You can then model directly on this terrain.
After modeling (for example, a house footprint), you can export the SketchUp edges back to GeoJSON for projection onto the real-world site—directly in the field via QField.
This tool bridges the gap between GIS data collection and architectural modeling in SketchUp.
