Overlay

What are overlays

An overlay is a layer drawn over the 3D world to illustrate different properties. They do not contain all the information of a given visualization, but serve as a supplement. By adding these properties onto the same view, the additional information can immediately be made understandable in the same way. A reason to split information off into other layers in this fashion can be to avoid overwhelming a user with too much information.

How do overlays relate to the Tygron Platform interface

Overlays are implemented in the Tygron Platform as part of the interface. Properties such as ownership and zoning are important pieces of information to the user, but would be very overwhelming to display at all times. Instead, a user can activate on overlay to make these pieces of information visible. In principle, all spatially varied information is accessible as an overlay.

How to access overlays

Overlays available to stakeholders appear as buttons on the right side of the interface. Clicking on any of these buttons will switch the view to the specific overlay. Clicking on the "City" overlay will switch the view back to default. Some overlays are automatically added when a project is created, see default overlay types. Some overlays are closely related to indicators, such as Heatstress and Livability.

Notes

Example of the Difference Overlay for Heatstress

The following overlays are available by default when creating a new project: City, Neighborhoods, Ownership and Zoning
Grid overlays have the ability to show the difference between the maquette and the original state. The difference visualization uses its own legend. The option to show the difference can be turned on or off per Grid Overlay. For more information, see: Main article: Difference (Overlay)

Adding and removing overlays

Template:Editor ribbon

Adding and removing overlays is a generic process, however, certain overlays are dependent on other assets being present too, such as indicators, terrains, vacancy, images, etc. For more information please refer to the respective main articles for the specific overlays.

How to add an overlay:

Select in the editor '3D World' from the ribbon
Select 'Overlays' > 'Edit overlays' from the ribbon bar
Select the desired overlay'*' from the drop down menu on the bottom of the left panel
Select 'Add' from the bottom of the left panel
Fill in parameters on the right panel, as required for some overlays
The overlay icon will now appear under the mini map'**'

1. Select 3D World

Sometimes it can be convenient to duplicate an already existing overlay. To do so, follow the steps for removal, but select 'Duplicate' in stead of 'Remove'.

'*' The default City, Zoning and Property overlays are already present when creating a new project in the editor. However, they can be removed and added again later.
