The rise of urban digital twins emphasises the critical role of representing real-world environments for decision-making and collaboration among stakeholders. This leads to an expectation of effective management and visualisation of large-scale urban data models. 3D Tiles is an open specification designed for streaming and rendering massive heterogeneous 3D geospatial datasets. It is widely adopted in fields such as urban planning and engineering construction, where geospatial data is crucial for decision-making and collaboration.

However, as the 3D data size grows, the performance of traditional file-based solutions is facing challenges. Currently, dissemination and visualisation of 3D data are often reliant on file-based systems. Users suffer from problems such as long load times, data inconsistencies, and lack of flexibility. In this thesis, an approach for compactly storing both geometries and attributes in the Database Management System (DBMS) and efficiently serving data compliant with 3D Web standards to the client is proposed, advocating the direct serving of 3D Tiles from the database.

Blind and visually impaired people currently have inconveniences locating themselves in the indoor environment. No standardized system exists for them yet. After an inventory of the requirements of blind people, different representations do qualify for providing specific information blind people need. The main research question is: "How can blind people localise themselves (near) real-time in indoor environments with the combination of 3 representations of reality, namely (1) LiDAR point cloud matching, (2) ArcGIS Indoors and (3) Audio dynamic tactile map as the user interface?". Room detection and positioning of the user within the room are obtained by LiDAR scanning and point cloud matching. The processed point cloud height raster grids are acquired and imported into the Esri ArcGIS platform. The rooms are geo-referenced, and data is enriched by contextual awareness. As a user interface for blind people this report proposes two deliverables: a dynamic tactile map and an added or stand-alone audible supported user interface. Preliminary results of the qualitative validation show positive outcomes. This report is a stepping stone for the possibility of integrating multiple into one device.
