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 2015.213071995_10153023876782168_3494588378664379377_o.jpg13047791_10153023877402168_3314891084468983365_o.jpg

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.
