<p><strong>Abstract.</strong> This paper presents diverse methods of photogrammetric surveys and applications in restoration works. It compares the methods of survey and highlights their advantages for each specific project. All the methods used showed the great advantage of photogrammetry, compared with the traditional method of survey. There is a great reduction of working hours (field and office). The restitution may be drawn up at any time, with the required degree of rigour, and may be more or less detailed depending on the needs of the Project, case of the dismantling of Cais das Colunas, in Lisbon. The single-image photogrammetry allows the restitution of flat elements, without information on their depth, which is ideal for surveying facades. In the Conservation project of the vaults of Jerónimos monastery church, the traditional stereophotogrammetry had the advantage of stereoscopic vision, allowing a careful observation of the details, anomalies of the construction and a precise diagnostic in situ. Photogrammetry of multiple images is a much faster method for obtaining the 3D model, through a dense cloud of points, which is the most commonly used in recent restoration projects, for heritage documentation and three-dimensional visualisation of the object. This last method was used to survey the church facade of the monastery of Alcobaça. The survey of São Miguel – o - Anjo lighthouse in Porto, and all the other cases, proved that photogrammetric restitution allows a detailed mapping of the construction, necessary for a correct diagnostic of the anomalies to support the Conservation Project.</p>

An analysis of urban morphology of the historical nucleus (the Plateau) of Praia (Cape Verde) highlights the process of thinking and making a city expressed in António de Lencastre 's plan and its further development. For this, the processes of urban transformation occurring over time in the Plateau are shown. The methodology used for this urban analysis allowed an understanding of the intervention process on the Plateau through an interpretative analysis of morphological evolution obtained from: i) a detailed identification of cartography; ii) a comparative morphological analysis of urban development based on old and current cartography; iii) a vectorization of the maps through scale normalization (the letters were overlapped with the 2018 chart); iv) an identification of public buildings and public spaces; and v) a quantification of the elements of urban form. In the quantification of the elements of the urban form, the reading and interpretation of the different maps is synthesized through analytical drawings and tables.
Abstract. Digital Revolution is strongly impacting the safeguarding and enhancement of Cultural Heritage through the techniques and tools available for its documentation and communication. Specifically, modern heritage is a potentially fertile laboratory of work in this field because of the availability of the documental, physical, and oral sources required for its critical study and interpretation. This article aims to present an integrated methodology supported by combined techniques for the comprehensive digital documentation of modern architecture implemented on 18 buildings of Álvaro Siza included in the World Heritage Tentative List since 2017 supported on combined techniques: i) photogrammetry; ii) virtual tours through 360° photos; iii) didactic models in BIM iv) other digital tools, such as virtual reality. This holistic and integrated multi-methods approach provides better documentation and communication of the attributes of the Outstanding Universal Value (OUV), as well as of Alvaro Siza’s design principles as a guiding framework for the future management of change.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
