The sky is the limit: reconstructing physical geography from an aerial perspective

In an era of rapid geographical data acquisition, interpretations of remote sensing products are an integral part of many undergraduate geography degree schemes but there are fewer opportunities for collection and processing of primary remote sensing data. Unmanned Aerial Vehicles (UAVs) provide a relatively inexpensive opportunity to introduce the principles and practice of airborne remote sensing into field courses, enabling students to learn about image acquisition, data processing and interpretation of derived products. Two case studies illustrate how a low-cost “DJI Phantom Vision+” UAV can be used by students to acquire images that can be processed using Structure-from-Motion photogrammetry software. Results from a student questionnaire and analysis of assessed student reports showed that using UAVs enhanced student engagement and equipped them with data processing skills. The derivation of bespoke orthophotos and Digital Elevation Models has the potential to provide students with opportunities to gain insight into various remote sensing data quality issues, although additional training is required to maximize this potential. Recognition of the successes and limitations of this teaching intervention provides scope for improving future UAV exercises. UAVs are enabling both a reconstruction of how we measure the Earth’s surface and a reconstruction of how students do fieldwork.     

Quality, imagery and marketing: producer perspectives on quality products and services in the lagging rural regions of the European Union

A range of factors, including consumer concerns about food safety, the growing popularity of rural tourism and policy initiatives to promote endogenous rural development, is converging to promote a relocalization of food production and service provision, especially in those regions marginalized by the globalization of the food supply system. The recent outbreak of foot and mouth disease in the UK has starkly illustrated the fragility of localized systems which depend heavily on consumers travelling to them. Within such a context, the importance of successful marketing strategies has become even more apparent. This paper reports on a questionnaire survey which investigated promotional and marketing strategies among a diverse range of producers and service providers in marginal agricultural areas of the EU. The findings suggest that many producers are situated towards the "formal" end of a marketing continuum, whereby ability to promote quality products and services (QPS) lies with a range of intermediaries. This raises doubts about the future economic benefits of QPS, should current marketing structures persist. The discussion offers critical reflections on interdisciplinary and international research of this nature, and advocates further theoretical and methodological development in order to explore in more depth many of the aspects raised in this exploratory investigation.     

Applications of satellite remote sensing for research and heritage management in Indian prehistory

Multidisciplinary spatial studies are relatively limited in Indian archaeology, despite their potential for research and heritage management. This paper discusses applications of satellite remote sensing, field studies and GIS, in the context of Palaeolithic archaeology. The study region covers an area of around 8000 km², in the state of Tamil Nadu, South India, and is characterized by a rich and diverse Palaeolithic record. Satellite images of varied spatial resolutions were interpreted to address both regional and site-specific research questions. Thematic maps were generated from satellite data and refined with intensive field investigations. These were used for demarcating sources of raw material, and in investigating variability in the distribution of sites through time in relation to a range of geological and geomorphological features. Satellite data and field studies also aided in mapping impacts on sites resulting from modern landuse patterns. The paper also discusses the development and testing of a model to detect potential areas where new sites may be rapidly located.     

Mapping ancient chinampa landscapes in the Basin of Mexico: a remote sensing and GIS approach

This paper uses remote sensing data to document a raised field, chinampa system adjacent to the Postclassic kingdom of Xaltocan in the northern Basin of Mexico. Various forms of landscape information; historic records and maps as well as remote sensing; are considered to understand the chinampa system. The remote sensing data examined include 1950s aerial photographs, Landsat 7 data, and Quickbird VHR, multi-spectral imagery. This article evaluates the utility of each of these forms of data to identify buried chinampa features and integrates them in a GIS to produce a map of Xaltocan's chinampa landscape. Canals of various sizes and hydrological positions comprised the chinampas and integrated the system together. Occupying at least 1500–2000 ha, Xaltocan's chinampa system represents the largest pre-Aztec, chinampa system in the Basin of Mexico.     

Radial route systems and agro-pastoral strategies in the Fertile Crescent: New discoveries from western Syria and southwestern Iran

Radial systems of spoke-like pathways, often termed “hollow ways,” are frequently found surrounding mounded tell sites in northern Mesopotamia and have been explained as the product of a particular set of land use practices involving dry-farming agriculture and intensive ovicaprid pastoralism. Yet while similar subsistence strategies were very common across the Near East throughout much of the Holocene, classic hollow ways have only been previously documented in a small region and articulate almost exclusively with sites of the third millennium BC. This paper presents newly discovered hollow ways in western Syria and southwestern Iran, made possible through analysis of an online database of declassified, Cold War-era CORONA satellite imagery. The association of these previously undocumented ancient roads with archaeological sites dating to the Iron Age, Roman/late Roman and early medieval periods, suggests that the land use practices which produced radial route systems may have been quite widespread. Taking into account the wide geographic and temporal distribution of hollow ways, analysis explores various aspects of the agro-pastoral systems that disparate communities may have shared. Results confirm some aspects existing models of hollow way formation, while offering some refinements in terms of the roles that settlement organization, agricultural land use and pastoral strategies play.

Space, culture and economy—a question of practice

This article addresses the current debate within geography and other circles studying urban and regional development of the relationship between culture and economy. It revolves around two arguments. First, that the relationship should be seen not only as a question of epochal change, of de-differentiation and culturalisation of the economy; it should be considered as an analytical rather than a historical question. Second, it is argued that a theoretical articulation may be gainfully employed starting from the level of social ontology-particularly an ontology of practice. These arguments are developed starting from a critical discussion of two dominant bodies of thought about the relationship, following which, a demonstration of the inseparability of practice and meaning is used to conduct a theoretical re-articulation of culture and economy. Finally, the spatiality of the culture economy relation is considered, displacing the emphasis from connectivity in bounded regions towards joint involvement in the production of space on different scales.     

Some Significant Recent Books in the Field of Mediaeval Literature

Although much has been written about André Breton’s concept of the Surrealist image, the present article examines a number of aspects that have so far escaped notice. In particular, it examines several antecedents of Pierre Reverdy’s theory of the image and compares the latter to that developed in the Manifeste du surréalisme. A close reading of the manifesto reveals the presence of a previously unknown model used by Breton in formulating his theory.     

New discoveries in the Piramide Naranjada in Cahuachi (Peru) using satellite,Ground Probing Radar and magnetic investigations

The detection of buried earthen structures by using remote sensing techniques is still an open issue and a strategic challenge as crucial as it is complex. It is crucial because earthen archaeological remains are widely present thoughtout the world (in South America, Asia, Africa) and it is complex due to the subtle physical contrast between earthen remains and the surrounding subsoil.     

Watching North Korea from the sky: Remote sensing and documenting human rights in the Democratic People's Republic of Korea

For organisations committed to documenting human rights abuses in North Korea, gathering data is an ongoing challenge. Faced with the lack of access to the country, as well as the problems inherent in verifying testimonies from North Korean escapees, some organisations have turned to hybrid methodologies, including pairing remote sensing (RS) technologies with testimonial data to better understand the people, places and institutions associated with human rights violations. In the case of North Korea, to date, remote sensing has been used primarily to monitor nuclear weapons and missile development sites. This work has at times sparked controversy, given the scope for analytical error and the high stakes associated with flawed analysis. Against this backdrop, this article discusses the application of remote sensing to augment human rights abuse investigations and calls for greater attention to the potential of remote sensing data to both assist in eliciting information in research interviews, and to generate data that may be used to support the pursuit of accountability for alleged violations of international law. Specifically, it considers the work of an ongoing project developed in South Korea using satellite imagery and Geographic Information Systems technology together with witness testimonies to document sites of state-led killings and burials in North Korea. The paper cites advantages to be had from developing hybrid methods of data-gathering in this context and describes some of the key methodological considerations involved, as well as the possible applications of the data in seeking justice and remedy in the future.
