Create a Noise Map on 3D City Model

GiuseppeMazzei — Sat, 07 May 2016 14:26:56 GMT

Hi ,

I'm an engineering student at the University of Calabria, Italy.

I'm creating a 3d city model with real gis data. I used CityEngine in a first stage.

I should make a noise map in 3d for my thesis but do not know how to do. Some Advice?

I have the shape file of the streets and buildings. The streets Shape include the noise levels.

That interpolation use in ArcMap to show the noise map? How do I represent the noise on facades of the buildings?

How do I create a noise map in 3d ?

Here is some images of the my scene created with CityEngine 2015.2

Thank you

This sounds like a cool project. I also like the look of your model.

Here is a suggestion....

1. Create the area around the streets representing the different levels of noise (possibly with a buffer / buffers OR a distance raster from the streets)

2. Create a "noise_level" attribute in the building shapes.

3. CityEngine - write CGA attr for and assign the facades a color based on the new noise_level attribute.

for example...

attr noise_level = 1 #connect this to your building shape "noise_level" attribute

noiseLevel = case noise_level == 1 : "#99192A"

case noise_level == 2 : "#B23343"

else : "#CC4C5D"

#Code to generate buildings

...

YourFacadeRule--> #This rule could color facades (or possibly roofs??) based on each buildings noise level

color(noiseLevel)

OR you could use a noise raster as a map layer type....

Help -

Hope this helps...let me know how it goes.
