SketchUp, noise3D und Google Earth

Noise3D online 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 online 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 online 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 online
    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.


Step-by-step instruction:


1. Import to SketchUp and noise3D online

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


Klick the Google Add Location icon which will present a new SketchUp window from
which a Google Earth location can be chosen, 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 online.
For the time being it may be appropriate to leave the Terrain toggled off (see
Google button Toggle Terrain), since noise3D version 2.0.2 does not yet fully
support a 3D Terrain (scheduled for launch with version 2.1).


2. Export to Google Earth

When you have completed the modelling in noise3D online and you want to show the
results in Google Earth then you can review it using the -> Preview
Model
in Google Earth icon.

Eventually, 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: Before exporting please make sure you have still toggled
off the terrain. Noise3D online does not yet support contour lines, however, the
noise map is always horizontal. 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 to find and apply photographic textures from Street View to walls in your model.
