STATUS: started
LOCATION: Czech Republic, Pilsen
TARGET AUDIENCE: citizens, experts
CHALLENGE
The City of Pilsen is planning to carry out several large-scale construction projects throughout the city in the coming years. Planning and city development is the responsibility of several city organizations that coordinate the city’s plans. The DUET application helps to plan new development and facilitate communication between the authorities and the public.
The DUET application allows the insertion of custom 3D data into an existing 3D model of the city. Thus, urban planners can visualize how the new development will look in the context of the existing one, try out the different project variants considered (e.g. height differences, variant building layouts, etc.), use the application’s functions to solve the shading of the existing development, find out information about traffic intensity, noise and air pollution in the area of the new development, try out new viewing perspectives created by the new development, draw their own 3D objects in the map composition, etc.
APPROACH
Use the DUET application to import different variants of residential buildings in Nepomucka Street. Use existing layers (3D city model, noise pollution, air pollution, traffic model) and application features to assess the appropriate variant of the planned development.
EXPECTED OUTCOME
The map visualization of the 3D model of the new development and the existing 3D buildings of the city, together with other layers available in DUET, will provide a new view of the location. The created visualizations are a suitable basis for presenting (communicating) the project to citizens, urban experts and policymakers to address issues related to the planned development (construction of new roads, parking lots, public transport stops, public lighting, playgrounds, planting new trees, etc.). As a result, a suitable project option should be proposed.
Opening the use case
Please note that after opening the case and logging in, you will need to reopen the case so that you can see the prepared layers.
To access the use case, click the “See this case live on DUET” button below
Then, you need to log in
Reopen the use case: https://platform.citytwin.eu/app/map?caseId=363
Displaying layers
Base layers are preselected: “Plzen – Traffic model”, “Plzen – Noise model”, “Plzen – Air pollution model”, “Plzen – 3D Buildings LOD2”, “Plzen – 3D Trees”and “Plzen – 3D Terrain model” Plzen – Public Transport Lines, Plzen – Public Transport Stops
To display the layers, click on the “Content” button in the main menu.
(If layers are not available in the “Content” menu, add them from the “Data” menu – tabs GeoJson, 3D data and Terrain data)
Download HERE both variants of the 3D model of the new development in Nepomucká street (part of the town of Bručná) in geojson format to your computer.
Turn on the Planner widget from the Widget menu:

Click on the New Project button to create your own project:

New project in planner widget
Enter the name and description of your project. Save the project.

Planner Widget – new project
Your project is created and included among the other projects. Start editing your created project with the “edit project” tool next to your project’s name and import the new 3D objects you have downloaded using the “Import planning object” button:

Import planning object
The new project can be published among the other public layers in the Content menu (see the image):

Planner widget: publishig the project
In the same way, create a project and import the second variant of the project for the construction of residential buildings in Nepomucka Street and publish it among the other layers in the Content menu in the Plannings category:

Planner widget: published project
Note: Don’t worry if you were not able to import both variants of the project into the map application. They are ready for you in the Planning section under the titles: “Plzen Brucna – Variant 1” and “Plzen Brucna – Variant 2”.
Try one of these tasks:
TASK 1:
Explore which parts of the new housing development will be exposed to noise and air pollution the most. (Hint: Use the available layers Plzen – Air pollution model and Plzen – Noise model)

Air pollution in new development area
TASK 2
Newly imported data can work with shadows like other existing 3D buildings. Try to shade new and old buildings in both variants of the project (see picture).

Shadows in new development area
You can also use other widget menu tools:
TASK 3:
Using the Measurement tool, measure for example the height difference between the buildings in variant 1 and 2 and the distance between the buildings and and their distance from the main road:

Measurements tool in Widget menu
TASK 4:
The Planner widget, which was used to import new data into the map, can also be used to draw your own objects into the map (Draw new object function). These can be predefined elements, such as trees, benches, public transport stops, etc., but the user can also draw their own point, line, area and even 3D objects into the map.
Try to project new public transport stops in the map based on existing routes and stops. Or you can draw the area of a newly considered playground or a kindergarten building. The video shows how to work with the planner widget.

Tomáš, all,
thanks for this excellent description of the Use Case – it was very helpful for me, during my exploration of contemporary status of DUET platform!
