# Urban Vulnerability Assessment of Sea Level Rise in Singapore through the World Avatar
## 4 Use Case
### Impact Assessment and Integrated Spatial Planning
This approach offers administrators both a broad overview visualisation of vulnerable areas from sea level rise and detailed indicators for each impacted asset and element, enabling more effective allocation of funding and resources [61]. The single unified representation datasets in buildings enable a more accurate and comprehensive representation for decision-makers. The unified representation facilitates the development of a common understanding and perspective of potential impacts on assets and property amongst various stakeholders which is essential for disaster risk mitigation [61]. This enhanced visual overview and augmented urban information can serve as a platform to communicate information more directly, as 3D representations of disaster risk with accurate scientific representation have shown to be beneficial in engaging stakeholders [61]. Site-specific granular assessment as seen in Figure 4 allows more precise identification of the properties that are affected. The augmented buildings with property usage and estimated construction cost offer a more accurate representation of vulnerable areas. This allows administrators prioritisation of sea level rise adaptation strategies for buildings that hold more significant value which could be either property usage type, estimated construction cost, gross floor area, or number of floors. One of the applications of this perspective is that knowing the estimated construction cost of a building can provide insights into the economic investment and potential financial risks associated with the properties prioritised for protection. Alternatively, evaluating a building from its property usage type perspective can enable prioritisation of buildings with essential services that are crucial to the community such as healthcare (i.e., hospitals, pharmacies, clinics), emergency services (i.e., police stations, fire stations, police station), or buildings that are important to the economy such as non-domestic types (i.e., industrial buildings, hotels, offices, banks). Similarly, the number of floors and gross floor area perspective of buildings enable resource allocation prioritisation for high-rise buildings which may pose greater challenges in terms of relocation, have a higher population density (e.g., residential buildings), or require better structural integrity against sea level rise. Ultimately, this site-specific granular assessment facilitates a strategic approach to resource distribution, enhancing the overall urban resilience of the city. The detailed cultural site also enables urban planners to visualise and assess the impacts of cultural sites with precision as seen in Figure 5. By knowing the names, locations, and descriptions of the cultural sites, planners can prioritiise conservation efforts based on the sites' significance and vulnerability to sea level rise. Local administrators can implement protective measures to safeguard and ensure that these significant cultural heritage cites are preserved with minimal damage. The detailed visualisation also streamlines the selection of adaptation strategies for the specific cultural site type such as whether to relocate or construct protective measures on the selected sites. Integrated spatial planning with sea level rise risk mitigation requires integration from various data from land use data, infrastructure, planning policy, and demographics [62]. TWA enables the integration of previously isolated data (i.e., population distribution, land plots, buildings, sea level rise vulnerable area) as seen in Figure 6 in a single visualisation. This unified visualisation enables sea level rise risk mitigation integrated with spatial planning strategies such as avoiding new/high-value developments at vulnerable zones while at the same time considering the underlying land use regulations, population distribution, and existing building infrastructures and services.
