Abstract
Purpose
The purpose of the study is to compare methodologies for mapping a historic building, with image capture by smartphones and drones, using photogrammetric techniques for three-dimensional (3D) modeling of the structure. Processes and products are also analyzed, as well as possibilities for storing and visualizing data for structuring a cadastre of historical and artistic heritage are studied.
Design/methodology/approach
For mapping with smartphones, the overlapping of photographs was guaranteed, with data acquisition using three different cameras, on the same date as the aerial survey. The models were made from different combinations of camera use. For storage, a conceptual model based on ISO 19.152:2012 is proposed, which was implemented in the MongoDB, resulting in a database for storage. The visualization was carried out on the Cesium ion platform.
Findings
The results indicate that the terrestrial 3D reconstruction using smartphones is an efficient alternative to the historical and artistic cadastre, presenting texture quality superior to the aerial survey in a shorter production time. When dealing with the conceptual model, the LADM (Land Administration Domain Model) standardization guarantees interoperability and facilitates data exchange. In addition, it proved to be flexible for the creation of thematic profiles, supporting their effective storage. The insertion of data in the visualization platform was simple and effective, and it even generated sharing links for visualization of the models.
Originality/value
The study analyses a low-cost method with the use of easily accessible devices, with a combination of methodologies and applied techniques. The data storage and visualization method is also simple and flexible, suitable for application in the cadastre of historical heritage.

Abstract
Purpose
The study, within the Increasing Resilience of Cultural Heritage (ResCult) project, aims to support civil protection to prevent, lessen and mitigate disasters impacts on cultural heritage using a unique standardised-3D geographical information system (GIS), including both heritage and risk and hazard information.
Design/methodology/approach
A top-down approach, starting from existing standards (an INSPIRE extension integrated with other parts from the standardised and shared structure), was completed with a bottom-up integration according to current requirements for disaster prevention procedures and risk analyses. The results were validated and tested in case studies (differentiated concerning the hazard and type of protected heritage) and refined during user forums.
Findings
Besides the ensuing reusable database structure, the filling with case studies data underlined the tough challenges and allowed proposing a sample of workflows and possible guidelines. The interfaces are provided to use the obtained knowledge base.
Originality/value
The increasing number of natural disasters could severely damage the cultural heritage, causing permanent damage to movable and immovable assets and tangible and intangible heritage. The study provides an original tool properly relating the (spatial) information regarding cultural heritage and the risk factors in a unique archive as a standard-based European tool to cope with these frequent losses, preventing risk.

Abstract
Purpose
This study aims to examine Braille usage among consumers with visual impairments, investigating motivations and addressing inherent challenges.
Design/methodology/approach
Drawing insights from 16 semistructured interviews with individuals experiencing blindness, this study reveals nuanced aspects of Braille utilization.
Findings
Three key motivations for Braille usage are identified: as a coping mechanism for functional needs and to combat stigma; as an embodied experience contributing to pleasure; and as a heritage embodying a culture of visual impairment. Obstacles include cultural and financial barriers to learning, incomplete retail transcriptions limiting practicality and spatial congestion issues.
Originality/value
This study underscores Braille’s dual function as both coping mechanism and cultural heritage. By highlighting obstacles, it sheds light on challenges faced by consumers with visual impairments, facilitating advocacy and promoting inclusive retail practices. Originality lies in recognizing diverse motivations and experiences among Braille users, offering insights for enhancing tactile engagement in the marketplace.
