Low cost survey and heritage value

SCIRES-IT : SCIentific RESearch and Information Technology, 2018

In the last two decades, the approach to surveying, profoundly modified by massive acquisition methodologies, has strongly influenced the construction of 3D models, which come closer and closer to reality. Various operations performed on numerical models prove to be necessary for defining geometric or mathematical models, which become ever more congruent with architectonic and archaeological artifacts. Today models are the point of departure for all the activities aimed at a more profound knowledge of the object. Different fields of operations connected with Cultural Heritage - from cataloguing to preservation, from designing to restoration and valorization - begin to present the enormous potentialities inherent in models obtained through 3D surveys. In some cases to observe artifacts in various scales and from different viewpoints, it is such to explore such models than the work itself. Moreover, they make it possible to design and prepare reconstruction, reinforcement and restorat...

Survey and Restoration: New Ways of Interaction

ISPRS - International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences

The present paper analyses two cases exemplifying a possible use of survey and its elaborations in the field of conservation: the bell tower of the Basilica Santa Maria delle Vigne and the Chiesa di San Matteo, both situated in Genoa. In the first case, the threedimensional survey was used as a basis to build a model for the structural analysis. The need for an accurate database created with the three-dimensional survey allowed the research team to determine and highlight the critical points of the structure as the thickness of vaults and floors, the location of loads and the inclination of the walls. The data collected was used to create an accurate 3D model to be tested with simulations, in order to verify the stability of the bell tower when applying stress and limitations. In the second case, the three-dimensional survey was used as the basis for the collection, management and representation of the data derived from the survey on rising damp. The purpose was to test a dynamic da...

The adaptations of the true-to-form survey method

Periodica Polytechnica Architecture, 2010

The following study is about the method of surveying historic buildings applied by the Department for History of Architecture and of Monuments of the Budapest University of Technology and Economics. The true-to-form architectural survey is based on the method used in "Bauforschung", the building archaeology practice developed and widely used in Germany. In this context, survey is not only a tool of documentation but is considered as a research method in itself. The authors discuss the importance of the on-the-spot analysis of the building and the role and place of architectural survey in the whole process of monument preservation, as well as the possible adaptation of the method presented under different circumstances. The examples are stages of the monument documentation work carried out on the Cathedral of Saint Michael in Alba Iulia (Gyulafehérvár), Romania.

Detailed Topography and Surface Survey. What is the point? Tanagra City Survey 2000

BAR INTERNATIONAL SERIES, 2002

"Topographical surveys and the creation of digital elevation models have become quite common in the archaeological projects. In the excavations they are used as a frame to locate the excavated area in a wider context. On the other hand, in artefact surface surveys, detailed topographical surveys produce a base layer over which the results of the collection can be lain. The paper aims to illustrate the topographical survey and the mapping of the architectural features visible on the surface carried out at the ancient city of Tanagra in Boeotia, Central Greece, as a part of a wider city survey project. The methodology used will be illustrated and examined, and the results will be analysed to evaluate their effectiveness for the final goals of the artifact surface survey project. Technical aspects will be illustrated and discussed together with the validity of the methods employed. Furthermore, from this analysis crucial methodological questions can be risen: is a topographical detailed survey useful only to map data resulting from the artifact surface collection, and to give us a general picture of the area we are working on? Or rather, by inserting the results as a layer into a Geographical Information System and linking it to a diversified database, could we gain new information and squeeze fresh juice out of something that would not be a mere Digital Elevation Model?"

INTEGRATED SURVEY FOR ARCHITECTURAL RESTORATION: A METHODOLOGICAL COMPARISON OF TWO CASE STUDIES

A preliminary survey campaign is essential in projects of restoration, urban renewal, rebuilding or promotion of architectural heritage. Today several survey techniques allow full 3D object restitution and modelling that provides a richer description than simple 2D representations. However, the amount of data to collect increases dramatically and a trade-off between efficiency and productivity from one side and assuring accuracy and completeness of the results on the other must be found. Depending on the extent and the complexity of the task, a single technique or a combination of several ones might be employed. Especially when documentation at different scales and with different levels of detail are foreseen, the latter will likely be necessary. The paper describes two architectural surveys in Italy: the old village of Navelli (AQ), affected by the earthquake in 2009, and the two most relevant remains in Codiponte (MS), damaged by the earthquake in 2013, both in the context of a project of restoration and conservation. In both sites, a 3D survey was necessary to represent effectively the objects. An integrated survey campaign was performed in both cases, which consists of a GPS network as support for georeferencing, an aerial survey and a field survey made by laser scanner and close range photogrammetry. The two case studies, thanks to their peculiarities, can be taken as exemplar to wonder if the integration of different surveying techniques is today still mandatory or, considering the technical advances of each technology, it is in fact just optional.
