According to the Act of 1996 on nature protection, mounds (kurgans) are natural monuments protected nationally in Hungary. According to the law, all kurgans in Hungary were to be surveyed by 2002, and 1692 were included in the cadastre. Fewer than half of the kurgans remained intact due to numerous anthropogenic impacts. A high number of disturbing artificial buildings together with soil erosion, soil removal, and afforestation have significantly reduced the landscape value of kurgans. In 2002, 51.5% of the surveyed kurgans still represented some kind of a value and thus their protection became one of the most urgent tasks of nature conservation and archaeology. According to a Hungarian ministerial decree, established on the basis of an EU Council decree, the area of kurgans under cultivation must be removed from cultivation. By 2015, in the area of 90% of the kurgans under cultivation this land use, which caused significant erosion, was terminated.  相似文献

Aerial photography provides a valuable recording method for archaeological sites and is often underutilized. In the past, aerial photographic platforms were expensive and often required highly specialized equipment. However, with new technology a variety of different platforms are now available. This paper will analyze two low cost aerial photographic platforms used at the Australian Archaeological Institute at Athens/University of Sydney's project at Zagora, on the island of Andros, Greece. Over two years, both kites and drones were used with relative success. Through a review of the application of both systems on the project, along with a quantitative analysis of the cost, transportability, operation and quality of photographs, the strengths and weaknesses of both platforms will be discussed.  相似文献

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

Grasslands pose a particular problem for archaeological survey involving artifact assessment, as no material is plowed up to the surface. Although finds in molehills are often the only source of information available on sites with such low visibility, an archaeology of molehills has thus far been largely disregarded. Yet, by applying a low-cost and time-efficient methodology, both the potential and the pitfalls of molehill archaeology come to the forefront. At the medieval harbor site of Monnikerede, it was possible to assess material culture and to locate certain structural elements. However, when artifact densities were compared with the underlying geophysical anomalies, a more complex relationship appeared at the level of individual features.  相似文献

Studies of old aerial photographs of the Bahrain burial mound fields have revealed that a small number of both Early Type (c. 2200–2050 BC) and Late Type (c. 2050–1750 BC) mounds are encircled by an outer ring wall, apparently marking out the mound as belonging to an elite. Four of these mounds have been excavated, and the results are presented. The geological differences between the Early Type and the Late Type mound landscapes are discussed.  相似文献

The combined application of remote sensing techniques is often the most effective way for deepening the knowledge on very large archaeological sites (several hectares). In particular, geophysics and aerial photography could yield very detailed information on buried structures not only outlining their location but also, in many cases, defining their planimetry. Moreover, the accurate geocoding of different data sets and the use of GIS for their integration allow to extract the most comprehensive information from a combined study.  相似文献

新时期,军事信息化的空袭战争表现出一些新的特征,人民防空肩负的历史使命也不同于以往那样单一。我国人民防空法明确规定:人民防空贯彻与经济建设协调发展、与城市建设相结合的原则。因此,积极做好战备工作、维护国家的安全与统一、保护人民的生命财产安全是人民防空的立业之本,推动城市经济建设是人民防空建设事业发展的基础。正确处理人民防空建设与城市建设的关系,对于促进人民防空建设与城市建设的协调发展意义重大。  相似文献

Abstract

Archaeological and cultural resource management analyses of sites of conflict of the recent past regularly draw on archival intelligence sources, in particular on aerial imagery. Like any other data source, they have their limitations. Using a case study, the World War II battlefield of Kiska in the Aleutians, this paper outlines the processes that generated these intelligence resources, as well as the factors that influenced their survival to the present day. Understanding these processes is necessary when using such sources to understand the development of cultural landscapes as well as specific sites.  相似文献

Abstract

Three seasons of fieldwork at the forced labour camp of Lager Wick, Grouville, Jersey (2014–2016) employed resistivity, ground penetrating radar (GPR) and magnetic susceptibility to investigate areas of the camp. Resistivity and magnetic susceptibility produced the most useful results, whilst the GPR survey only revealed a modern pipe. The resistivity survey was undertaken in the south-west corner of the former camp close to the entrance gate posts, whilst the magnetic susceptibility survey was undertaken over the remains of one of the barrack huts along the Gorey Road frontage which had been burnt to the ground in 1943. The resistivity survey produced some high resistance anomalies that appear to resemble a demolition layer or a surface on which the huts were constructed. Magnetic susceptibility results showed zones of burning which appear to relate to the remains of one of the burnt huts; excavation revealed a stone/brick surface.  相似文献

Although geography has long associated itself with photography, the rapid advancement of technology has created a clear divide between the visual practices regularly used in wider society and the way photography is utilized by critical geographers in their teaching. We suggest the door is ajar for new modes of (geo)photographic thinking, and one visual tool at our disposal is social media applications that allow images to be instantly shared, analysed, and discussed. This article critically reflects on the use of Instagram to enhance student participation, engagement, and learning on a geography field course in Berlin. Based on interviews with students, their field journals, and our own critical reflections, this paper looks at some advantages of using Instagram in teaching geography, but also promotes caution and presents drawbacks to relying on instant visual digital methods.  相似文献
