The recording and 3D modelling of complex archaeological sites is usually associated with high capital and logistical costs, because the data acquisition must be performed by specialists using expensive surveying sensors (i.e., terrestrial laser scanners, robotic total stations and/or ground‐penetrating radar). This paper presents a novel, low‐cost, user‐friendly photogrammetric tool for generating high‐resolution and scaled 3D models of complex sites. The results obtained with unmanned aerial vehicle (UAV) photogrammetry of an archaeological site indicate that this approach is semi‐automatic, inexpensive and effective, and that it guarantees quality.  相似文献

This article examines the extent to which states are able to interact at an official level with a contested or de facto state—a state that has unilaterally declared independence but is not a member of the United Nations—without being understood to have recognized it. This is an area of increasing interest and relevance to policy‐makers as the number of contested states has grown in recent years. In many cases, interaction may be important for ongoing peace efforts. However, there are also instances when a state is prevented from recognizing the territory in question for specific domestic or foreign policy reasons and so has to find alternative means by which to cooperate. Drawing on several key examples, notably Kosovo and the ‘Turkish Republic of Northern Cyprus’, but also with reference to Abkhazia, the article explores the limits of interaction across various different forms of bilateral and multilateral diplomatic activity. As is shown, albeit with some significant provisos, legal theory and historic practice suggest that diplomatic engagement does not constitute recognition if there is no underlying intent to recognize. This means that there is in fact a very high degree of latitude regarding the limits of diplomatic engagement with contested states. This is especially the case in bilateral contexts. Indeed, in some circumstances, the level of engagement can even amount to recognition in all but name.  相似文献

Despite their theoretical and political potential, recent debates on enclosure usually lack an effective consideration of how space is mobilized in the process of dispossession. This article connects the analysis of enclosure's general spatial rationality to a range of illustrations of its particular formations and procedures. Enclosure is understood as one of capitalism's “universal territorial equivalents”, a polymorphous technique with variegated expressions in time but also with a consistent logic that uses the spatial erosion of the commons to subsume non‐commodified, self‐managed social spaces. In response to the ever‐changing nature of commoning, successive regimes of enclosure reshape the morphologies of deprivation and their articulation to other state and market apparatuses in order to meet shifting strategies of capital accumulation and social reproduction. Through a spatially nuanced account of these phenomena, I outline a tentative genealogy of enclosure formations that allows tracking diverse geographies of dispossession across different scales and regulatory contexts in various historical stages of capitalist development.  相似文献

This paper evaluates the impact of accessibility on the productivity of Spanish manufacturing firms. We suggest the use of accessibility indicators of workers and commodities, integrating transport, land use, and individual components, computing real distances or traveling times using the Spanish full road network. Estimated firms’ total factor productivity is explained as a function of the accessibility indicators and additional control variables. Results evidence the crucial role on firms’ productivity to the accessibility of commodities and to a slightly lesser extent the workers.  相似文献
