For research on (3D) noise mapping, I calculated the noise levels that reach the facades of buildings. The first picture shows the houses in 3D that I have used to determine the facades for the noise calculations.

With the software program GeoMilieu (a spatial noise calculation program) I calculated on vertical grids with an distance interval of 1 meter on all facades. This resulted in the following output (a shapefile opened in ArcScene):

Noise levels (from purple to green) on building facades

The small gaps between buildings are caused by the fact that the interval is 1 meter, and only intermediate values could be interpolated, leaving the edges empty of calculated noise data.

However, when I open this exact same shapefile in ArcGIS Pro, I get a totally different visualization:

Same shapefile opened in ArcGIS Pro

I have no clue how this difference could happen.

  • It is not something with the symbology (I tried everything there)
  • Both shapefiles have the exact same amount of Polygon ZM objects in the attribute tables.
  • The 'white' missing parts in the ArcGIS Pro visualization cannot be selected or identified, in ArcScene clicking on the exact same part of a building (even though 'visualized') does not result in a selection or identification.
  • The white parts are always the same parts and are not 'flickering' or changing when panning around in the 3D modus (no rendering issues)
