The COVID-19 display system, which data was provided by the Central Epidemic Command Center public daily reports, traces the accumulation of populations who suffered from the Coronavirus disease at the county level. It could explain the change of COVID-19 during that period in Taiwan.

The Noise Map service, which collected sounds from Sound Box devices around Taipei City, was provided by the Center for GIS, RCHSS of Academia Sinica, and leveraged the 3D building data from the National Land Surveying and Mapping Center, MOI. People can easily see the volume of the sounds change as time passes and lead to different experiences of different floors.

The Smart Agriculture Platform, which focused on the main crop statistics and analysis, the data was collected by the Agriculture Bureau of Kaohsiung Government and integrated the Crop AI models to identify the area of crops. People can understand the statistics of the volume of the crops.

In order to increase the geospatial integration abilities of water resource agencies. NCHC co-works with the Water Resources Bureau of the Taichung City Government and focuses on how to repeat the historical flooding case of the Wuxi Basin with a digital twin concept. According to historical water resources data build up the early alarm system of the pumping station by applying an AI water level recognized.

This 3D ocean and air information platform collected flight information, satellite trajectories, and shipping boats' GPS information. It could manage, arrange, and search certain objects to get real-time situations around the Taiwan.

The 3D GIS underground pipelines platform is co-working with the Tainan government and leverages the 3D building data from the National Land Surveying and Mapping Center, MOI. It tries to provide a communication website that could record the location of pipeline conflict and save the conflict’s negotiation Process.

The comprehensive Geographic Information System (GIS) convenience display platform, a collaboration between the National Center for High-Performance Computing and Keelung City Government, not only features a 3D display of Keelung's city buildings and topography but also integrates functionalities such as real estate transaction registration, land registration inquiry, soil and water conservation, fire prevention and disaster response, urban planning, and multi-window historical data comparison.

The cloud-integrated geographic information service display platform, a collaboration between the National Center for High-Performance Computing and Nantou County Government, integrates tools such as public IoT information, road maintenance results, and existing building inspection. Additionally, it offers features like travel diaries to promote tourism for the public and tourism industry professionals.

To ensure the effectiveness of hydrological numerical model applications, data is compiled and categorized based on the start and end times and rainfall conditions affecting the regions during historical flooding events. The process is visualized in a 3D platform to simulate the flooding progression, enabling users to quickly understand the flooding history in the Hsinchu area.

Through the dynamic display of moving objects (vehicle models), various features of the platform's timeline are presented, such as dragging the timeline to correspond to object positions and adjusting playback speed.

Using Pingtung as a demonstration area, the flood numerical model can simulate hourly flood extents, providing high accuracy in monitoring water level changes within the observed range. The National Center for High-Performance Computing's 3D GIS platform can integrate real-time simulation analysis data from Datacube, offering precise flood extent and water height information. This aids relevant agencies in making informed decisions for disaster prevention and preparation.

Using Taichung as a demonstration area, the flood numerical model can simulate hourly flood extents, providing high accuracy in monitoring water level changes within the observed range. The National Center for High-Performance Computing's 3D GIS platform can integrate real-time simulation analysis data from Datacube, offering precise flood extent and water height information. This aids relevant agencies in making informed decisions for disaster prevention and preparation.

The National Land Surveying and Mapping Center of the Ministry of the Interior provides building data for all counties and cities in Taiwan on the "Multi-Dimensional National Spatial Information Service Platform." This platform can integrate 3DTiles building data streams and display them in real-time virtual reality.

Through images captured by drones and using oblique photography to transpose buildings, digital twin city models can be produced. This platform not only allows for the display of such city buildings on regular web pages but also offers virtual reality (VR) tour technology, enabling users to immerse themselves in virtual scenes.

"The underwater topography extension module provided by this platform can display underwater terrain on regular web pages and also offers virtual reality (VR) tour technology, allowing users to immerse themselves in the underwater world around Taiwan. VR Operation Instructions: When using a VR headset or simulator, enter the webpage, move your viewpoint to the desired location, and click the ""VR"" button to enter the VR environment. If the ""Show Ocean Surface"" option is selected, the view will transition to an underwater effect when the perspective is below sea level."

The underground pipeline extension module provided by this platform can display underground pipelines on regular web pages and also offers virtual reality (VR) tour technology. This allows users to observe the relative positions of pipelines in VR space more directly. VR Operation Instructions: When using a VR headset or simulator, enter the webpage, open the Widget, and select the objects you wish to observe. The viewpoint will move to that location. At this point, lowering the transparency will display the pipeline data. After fine-tuning the viewpoint position, click the "VR" button to enter the VR environment and observe the pipelines.

本平台提供的BIM建物模型模組，除了可於一般網頁展示BIM建物模型，亦提供虛擬實境導覽的技術，可讓使用者透過 VR 於建物內部空間行走，可做VR室內導覽的相關應用。

The video uses the Ludao Map Platform as an example to demonstrate the functionality of multi-user connections of 3DGDP.
