    COMPARISON OF LOW COST PHOTOGRAMMETRIC SURVEY WITH TLS AND LEICA PEGASUS BACKPACK 3D MODELS

    This paper considers Leica backpack and photogrammetric surveys of a mediaeval bastion in Padua, Italy. Furhtermore, terrestrial laser scanning (TLS) survey is considered in order to provide a state of the art reconstruction of the bastion. Despite control points are typically used to avoid deformations in photogrammetric surveys and ensure correct scaling of the reconstruction, in this paper a different approach is considered: this work is part of a project aiming at the development of a system exploiting ultra-wide band (UWB) devices to provide correct scaling of the reconstruction. In particular, low cost Pozyx UWB devices are used to estimate camera positions during image acquisitions. Then, in order to obtain a metric reconstruction, scale factor in the photogrammetric survey is estimated by comparing camera positions obtained from UWB measurements with those obtained from photogrammetric reconstruction. Compared with the TLS survey, the considered photogrammetric model of the bastion results in a RMSE of 21.9cm, average error 13.4cm, and standard deviation 13.5cm. Excluding the final part of the bastion left wing, where the presence of several poles make reconstruction more difficult, (RMSE) fitting error is 17.3cm, average error 11.5cm, and standard deviation 9.5cm. Instead, comparison of Leica backpack and TLS surveys leads to an average error of 4.7cm and standard deviation 0.6cm (4.2 cm and 0.3 cm, respectively, by excluding the final part of the left wing)

    Approach to comprehensive analysis of bastion castle ensemble with historic gardens: novel combined strategy

    Full text link
    [EN] Bastion castle ensemble is a complex structure that belongs to defensive residences, which usually include the historic gardens and play an important role in the formation of the townscape. The two main structural components of such built complexes are palatial body and bastion fortifications. However, some bigger ensembles can also include other functional buildings. Due to the nature of the structure, namely the presence of defensive elements, which followed military development, many bastion castles underwent huge transformations. They were built and rebuilt because of the outdated design or destruction by the enemy. That is why studying such ensembles only from a historical perspective or analyzing only their fortification part is not enough to understand the whole complex, which is much more than a single-type building. In contrast, this paper proposes an interdisciplinary approach to studying bastion castles on the example of a bastion castle in Zheshov (Poland). Specifically, this paper uses a combined strategy that includes interpretative historical and qualitative-computational strategies as a systematic and comprehensive approach to the research. This strategy consists of seven points of analysis: historical transformations, composition, situation, landscape, fortifications, typomorphology, and space syntax. This work represents a methodological framework that can be used for the analysis of any bastion castle ensemble in the world.These are the methodological approach representation that is planned to be used in the project: “Jacques Perret Influence on Defensive Polish Architecture in the 17th Century”.

    “The Union Forever”: Frederick, Maryland in the Elections of 1860 and 1864

    Full text link
    Frederick, Maryland has been remembered as a bastion of Unionist sentiment during the Civil War. However, in the Election of 1860, on the eve of the nation’s internal conflict, a large portion of the city’s 8,000 residents voted for a secessionist candidate. The Election of 1860 is famous for straying from the typical bi-partisan election; four candidates ran for office and each appealed to different political sentiments. [excerpt

    William Drummond and the Battle of Fort Erie

    The officers and men of the British army that defended Canada from American invasion during the War of 1812 knew they were “forgotten soldiers.” Fighting in a distant and secondary theatre, far from the gaze of a government and public pre-occupied with events on the continent, especially in Spain, they took a somewhat perverse pride in their status as outcasts. As one quipped about the Duke of Wellington—“thank God he managed to do without us” at Waterloo. But they also took a particular pride in their own local heroes including such men as Gordon of the 1st Regiment of Foot, Robinson of the 8th Foot, Glew of the 41st, Fitzgibbon of the 49th, Morrison of the 89th, Dawson and Tweeddale of the 100th, Scott of the 103rd and—perhaps most renowned of all—Lieutenant Colonel William Drummond of the 104th Foot

    Micropalaeontology reveals the source of building materials for a defensive earthwork (English Civil War?) at Wallingford Castle, Oxfordshire

    Microfossils recovered from sediment used to construct a putative English Civil War defensive bastion at Wallingford Castle, south Oxfordshire, provide a biostratigraphical age of Cretaceous (earliest Cenomanian) basal M. mantelli Biozone. The rock used in the buttress – which may have housed a gun emplacement – can thus be tracked to the Glauconitic Marl Member, base of the West Melbury Marly Chalk Formation. A supply of this rock is available on the castle site or to the east of the River Thames near Crowmarsh Gifford. Microfossils provide a unique means to provenance construction materials used at the Wallingford site. While serendipity may have been the chief cause for use of the Glauconitic Marl, when compacted, it forms a strong, almost ‘road base’-like foundation that was clearly of use for constructing defensive works. Indeed, use of the Glauconitic Marl was widespread in the area for agricultural purposes and its properties may have been well-known locally

    Giorgio Agamben's Creation and Anarchy is comprised of five meditative essays compiled over the last few years and presented as an anthologized collection. The initial few chapters' survey postmodern art qua divinity, with particular interest to a contradictory dialectic: inspiration and critique. Drawing from an idiosyncratic amalgam of thinkers–ranging from bastion thinkers such as Kant and Heidegger to zoologist Jacob von UekĂŒll and prescient media philosopher Gilbert Simondon–Agamben carves a historiographic lineage between politics, animal studies, landscape painting, and religion
