    Integration of historical GIS data in a HBIM system

    The integration between BIM (Building Information Modeling) and GIS (Geographic Information System) is currently a highly debated research topic. However, the effective integration of the two workflows in a unique information system is still an open research field, especially when dealing with Cultural Heritage (CH). The paper describes an ongoing research on the development of a web information system able to integrate BIM and GIS data, with particular focus on the analysis of the historicized city and its main buildings over time. Three main aspects, in particular, are considered more relevant: (i) conceptual data organization to integrate GIS and BIM in a single environment; (ii) integration of data belonging to different historical periods for analyses over time (4D); (iii) integration into the system of datasets already structured in pre-existing HGIS and HBIM. Most (if not all) of the attributes must be linked with both 2D and 3D entities. The system should be queryable and with the possibility to edit the information regardless of the actual focus of the current user, either if he is more BIM or GIS oriented. This is one of the main requirement for the system not to be just a simple viewer of BIM and GIS data in a unique software environment. The system can manage, from a spatial point of view, different scales of detail, allowing the connection between data from the architectural scale to the territorial one and, from a temporal point of view, data belonging to different periods. All these features have been designed to meet, in particular, the requirements of CH and realize a Historical BIM-GIS system. Besides, the web architecture allows sharing information even between actors with different digital skills, without the need for specific software installed, and ensures portability and access from mobile devices

    Official Statistics, Building Censuses, and OpenStreetMap Completeness in Italy

    The present study provides a simplified framework verifying the degree of coverage and completeness of settlement maps derived from the OpenStreetMap (OSM) database at the national scale, with a possible use in official statistics. Measuring the completeness of the objects (i.e., buildings) derived from OpenStreetMap database supports its potential use in building/population censuses and other diachronic surveys, as well as administrative sources such as the register of building permits and land-use cadasters. A series of measurements at different scales are proposed and tested for Italy, in line with earlier studies. While recognizing the potential of the OpenStreetMap database for official statistics, the present work underlines the urgent need of an additional (spatially explicit) analysis overcoming the data heterogeneity and sub-optimal coverage of the OSM information source

    Wired! and Visualizing Venice: Scaling up Digital Art History

    Get PDF
    This article focuses on Visualizing Venice, an interdisciplinary, cross-cultural collaboration that engages in mapping, 3-D modeling, and multimedia representations of historical change in Venice, Italy. Through a “laboratory” approach that integrates students and faculty in multi-year research teams, we ask new questions and pursue emerging lines of inquiry about architectural monuments, their relation to the larger urban setting, and the role of sculptural and painted decoration in sacred spaces. Our practice of digital art history transforms both teaching and research and provides new means for communicating knowledge to a broad public

    The Column of Trajan in the light of ancient cartography and geography

    Get PDF
    The spiral reliefs of the Column of Trajan at Rome present the narrative of the Dacian Wars upon a continuous and elongated cartographic landscape, in which a wealth of landforms, including mountains, rivers, streams, springs, and forests serve not only as a setting of human actions, but become elements of the narrative in themselves, as they yield to the relentless efforts of Trajan and his army and engineers. In depicting the campaigns, the reliefs celebrate to a remarkable degree the military engineers and agrimensores (surveyors) who transformed the land as they cleared, measured, and built during the wars. In a circuit from participation in the historical events to their commemoration, the work of these surveyors ultimately contributed to the design of the Column and the stylistic choices of the Column reliefs themselves. Not only the subjects, but the innovative spiral format and the mode of depiction of the Reliefs are indebted in part to the conventions ofcartographic practice, while the conceptual framework within which the column’s topographic depictions communicatetheir ideological freight is tied to traditions of ancient geography. Writers such as Strabo, Pliny and Dio Cassius, whileproviding inconclusive evidence on the locations of topography in the Reliefs, point to the worldview they express: civilizing,imperial, scopic, rational, organizing, controlling nature. This essay examines the Column reliefs as embedded in widertopographical and geographical traditions during Trajan’s reign and in Roman antiquity, and proposes some new avenuesfor understanding the reliefs in these term

    On the origin and persistence of praedial toponyms in central Italy

    Get PDF
    This paper recognises the origin of the current series of praedial place names, through successive transcripts, in the Roman land ownership system of republican and imperial times, experimenting with some methodological aspects of the use of digital cartographic sources. Acknowledging the widespread presence of praedial place names in modern cartography and medieval notarial sources, the research reconstitutes the history of the land ownership system, considering the landscape as “quella forma che l'uomo, nel corso ed ai fini delle sue attività produttive agricole, coscientemente e sistematicamente imprime al paesaggio naturale” [“the form that man, in the course and for the purpose of agricultural production, consciously and systematically imposes to the natural landscape”] (Sereni, 1961, p. 29). The two sets of data, morphology and toponymy, are proposed here as an antonymic dyad representing the symbolic relationship between population and territory. The research considers two case studies: the valley of the river Savio, and the territory belonging to the abbey of Subiaco in the Lazio region. After the close examination of toponyms in the Italian official map (scale 1:25,000) a list of praedial names was selected and, with a GIS, was correlated with another set of place names extracted from medieval notarial documents (IV-XII cent.). For some of these place names it was possible to track back the history of the site to the Roman praedium and in three cases to identify the Roman owner, through the analysis of literary and epigraphical sources. Starting from these three specific praedia it was therefore possible to infer the origin and the history of praedial place names in central Italy. Nevertheless, the persistence of these names until today was possible only through the medieval notarial transcriptions, showing some continuity in the land ownership system through the Middle Ages

    CapacitĂ  di accumulo di metalli in una specie mediterranea: Nerium oleander L. a Palermo (Sicilia, Italia)

    ABSTRACT- Capacity of atmospheric pollutants accumulation of an ornamental mediterranean species: Nerium oleander L. at Palermo (Sicily, Italy) - The role of Nerium oleander L. as bioaccumulator of atmospheric contaminants was studied. Material was collected in six sites of the city of Palermo (Sicily, Italy) every two months from April 1998 to June 2000. Total concentration of Al, Ba, Cd, Cr, Cu, Fe, Mg, Mn, Ni, Pb, Zn and V was measured in washed and unwashed leaves. This study demonstrates that there are differences in accumulation capacity amongst the twelve studied elements. This species can not be considered hyperaccumulator of any of the studied elements. High correlation was observed between manganese and barium

    Surveying Curriculum from the Point of View of Multidisciplinarity

    The multidisciplinarity and globalization makes fade the differencesamong professions and surveying is no exception. CLGE – CLGE has aname in two of the many European languages English and French, namely“The Council of European Geodetic Surveyors” and “ComitÂŽe de Liaisondes GĂ©omĂštres EuropĂ©ens”. A “Multilateral Agreement” on mutualrecognition of qualification in surveying was signed in 2005 inBrussels by representatives of Germany, France, Belgium, Switzerlandand Luxembourg. In 2006 also Slovakia joint this Agreement.  Thesignature by the Czech Republic is recently under discussion
