Noise3D working with SketchUp® and Google Earth© is an outstanding toolset for noise calculation and mapping. Google Earth providing a user chosen Terrain into SketchUp and noise3D allowing acoustic modeling are a perfect setup for providing professional planning results for noise control engineering.
The concept works as follows:
- SketchUp allows you to import a terrain from Google Earth which will become your floor plan for acoustic modeling.
- Noise3D leverages the 3D capabilities of Sketchup and enables users to create sophisticated acoustic models “placed” on Google Earth terrain.
- When the noise calculation results have been calculated noise3D allows you to export the acoustic model and the noise map into Google Earth on your PC.
- The compelling results will convince your customers and any interested people.
- The model will not be loaded into public Google Earth.
1. Import to SketchUp and noise3D
If you intend to start your project with a floor plan from Google Earth please launch SketchUp and enable the Google tools
SketchUp → View → Toolbars → choose Google
(pls. note that from SketchUp 2016 the term “Google” is replaced by “Location”). Klick the “Add Location” icon which will present a new SketchUp window from which a Google Earth location can be chosen (you may have to expand the new window to the right…), zoom in and → Select Region adjust as required and → Grab.
The picture grabbed will become your floor plan for your project. Please save the project and proceed with acoustic modeling in SketchUP and noise3D. For the time being it may be appropriate to leave the Terrain toggled off (see button “Toggle Terrain“). For more details about how to effectively create a model in a terrain we strongly recommend that you also read through the noise3D manual, section “Terrain“.
2. Export to Google Earth
When you want to present the results in Google Earth please proceed as follows. In SketchUp export the model:
SketchUp: File → Export → 3D Model
and chose export type Google Earth File (*.kmz). A PC directory and a file name can be chosen for the transfer of data, then click “Export“.
(Note: With Google Earth surface being at different heights it may be required to elevate the noise map above ground. This is possible with a new plugin function “drop at …“. We typically elevate noise maps a few meters above ground so that they become fully visible. Where you have steep slopes in your terrain it may be required to elevate the noise map even a bit higher)
Now open Google Earth and proceed with the import:
Google Earth: File → open
and select the file which has just been stored in the previous step.
Google Earth will now show the noise3D online import as “Created with SketchUp” (menu left side) and you will find model and noise map properly laid down on Google Earth. In case you want to further refine the acoustic model please use the Google →Photo Textures icon in SketchUp to find and apply photographic textures from Street View to walls in your model.
