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 in a project
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.
List of Available Overlays
Notes
- 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)
Buildings overlays
Vacancy
- Main article: Vacancy (Overlay).
- This overlay shows all constructions in the project area which have been set as vacant in the Editor.
Neighborhoods
- Main article: Neighborhoods (Overlay).
- This overlay is available by default and shows the division in neighborhoods and statistics concerning those areas.
Ownership
- Main article: Ownership (Overlay).
- This overlay is available by default. This overlay displays the ownership of properties across the entire project area, using each stakeholder's colors. This is important when considering which stakeholder may perform actions such as constructing or demolishing at a given location, or whom to negotiate with for land transactions.
Zip codes
- Main article: Zipcodes (Overlay).
- This overlay displays the division into 6-digits zipcode areas.
Zoning
- This overlay is available by default. The overlay displays the zoning plan for the entire project detail area. This is helpful when considering indicators which are scored per zone, and when looking to construct a building which is restricted to certain zones.
Landscape overlays
Heightmap
- Main article: Heightmap (Overlay).
- This overlay displays the height of the terrain. The overlay becomes available for all stakeholders when added to a project.
Underground
- Main article: Underground (Overlay).
- This overlay displays the underground terrain composition. The overlay becomes available for all stakeholders when added to a project.
Water overlays
Terrain Flooding
- Main article: Terrain Flooding (Overlay).
- This overlay displays active flooding areas. This overlay becomes available for each stakeholder.
Rainfall
- Main article: Rainfall (Overlay).
- This overlay calculates the flow of water across the 3D world both above ground and underground, to provide insight into inundation intensities and durations. This is an expert hydrology module. It becomes available for all stakeholders when added to a project.
Subsidence
- Main article: Subsidence (Overlay).
- This overlay calculates the subsidence of peat in the project area. The subsidence can be caused by oxidation and compaction of the soil. This overlay is part of the Subsidence calculation collection of overlays.
Custom overlays
Areas
- Main article: Areas (Overlay).
- The Areas overlay displays a combination of selected active areas. This overlay becomes available for each stakeholder.
Attribute
- Main article: Attribute (Overlay).
- The Attribute overlay highlights geographical data which has a specific attribute. This overlay becomes available for each stakeholder.
Average
- Main article: Average Overlay.
- The Average Overlay displays an attribute value from a building, terrain, area or neighborhood assigned to a grid cell. This overlay becomes available for each stakeholder.
Custom Color Areas
- Main article: Custom Color Area (Overlay).
- This overlay shows colored areas in the 3D world, in locations defined in the editor.
Function Highlight
- Main article: Function Highlight (Overlay).
- This overlay highlights all constructions in the 3D world, for which the specific function has been selected, such as all shops in an area.
Geotiff
Image
- Main article: Image (Overlay).
- This overlay can be used to visualize a geographically referenced Image.
Source
- Main article: Source (Overlay).
- The Source overlay displays the datasets/sources that are used for and in the project. This overlay becomes available for each stakeholder.
Adding and removing overlays
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.
- 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
- SelectEditOverlay.jpg
2. Select Overlays > Edit overlays
- SelectDropDown.jpg
3. Select desired overlay from drop down menu on the bottom of the left panel
4. Select 'Add' from the bottom of the left panel
- OverlayParameters.jpg
5. Fill in parameters on the right panel (required for some overlays)
- OverlayIconPresent.jpg
6. The overlay icon will now appear under the mini map
- Select in the editor '3D World' from the ribbon
- Select 'Overlays' > 'Edit overlays' from the ribbon bar
- Select the desired overlay'*' from the list of active overlays'**' on the left panel
- Select 'remove' from the bottom of the left panel
- Confirm the removal in the pop up confirmation message
1. Select 3D World
- SelectEditOverlay.jpg
2. Select Overlays > Edit overlays
- SelectOverlay.jpg
3. Select desired overlay from the list of active overlays on the left panel
4. Select 'Remove' from the bottom of the left panel
5. Confirm the removal in the pop up confirmation message
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.
