Methods of representation:

Grids

•Grid, defined by its resolution:

oThe Resolution corresponds to the distance that a pixel represents. A resolution of 5m means that 1 pixel = 5m. To avoid excessive interpolation, this value should be related to the receiver resolution chosen for the simulation.

oThe Interpolate in buildings option makes it possible to obtain a complete map with buildings. This option modifies the simulation of areas.

oIf several simulation heights have been entered during creation of the domain, a drop down menu allowing you to select the height of the map is available.

Important: A grid map will not be "flat" in 3D view. The dB value is stored in the Z of the pixels of the grid for the export. Due to that, in 3D view, the Z of the pixels will be interpreted as an elevation and the map will be in relief.

Points

•Points directly representing the simulation receivers:

oWith the None option, there is no visualization (optimization to have a quick access to population information and statistics).

oThe Max dB option allows you to see the maximum level value for each building.

oThe Attribute on 'Building' overlay corresponds to the name of the attribute that the user can add to each building: its value is the dB Max value simulated on the building.

Isovalues

•Iso values i.e. the lines drawn to the level values indicated by the user:

oThe update iso values window is accessed via the button (see Update iso values).

oIso values must be separated by a ';'.

oAll negative values are ignored.

oValues can be entered in any order.

Polygons

•Polygons i.e. areas drawn to the level values entered by the user:

The button gives access to the update window for the iso values (see Updating iso values).

The Faces fusion of same interval option allows you to concatenate the faces (forming a facade) included in the same value interval. The consequence of this is that fewer face objects are shown in the view. However, if you do not select this option you can retain the exact level of 'face' objects so the information is not impaired.
