Digital analysis of Landsat data is applied to up-dating land cover maps for the Goondiwindi district of southern, inland Queensland. The imagery was paired with climax cover maps obtained from land systems reports with analysis conducted separately for each of three climax cover types (open forest, woodland and open woodland). Computer classification using this approach produced readily interpreted and reliable results. This work demonstrates that Landsat can be used in conjunction with existing, land systems derived maps to produce data that combine the advantages of two approaches to environmental survey, the former being based on current land cover/land use and the latter on the original environment and its land use potential.  相似文献

The author finds that population maps in national atlases should, as a minimum, treat population from four aspects: population numbers and density, geography of settlements, social and economic characteristics, and ethnographic characteristics. He notes that published national atlases generally slight the social and economic aspects in favor of strictly demographic characteristics of population.  相似文献

A complete climate section of a national atlas should contain maps, tables and graphs presenting data on climate-forming factors, the temperature regime, moisture supply, climatic regions and typical weather situations. Published national atlases are analyzed and recommendations for the treatment of climate are made. Particular importance is attached to the integrated presentation of several climatic elements on a single map. The value of climatic maps for various segments of the economy (agriculture, construction, transportation) is emphasized.  相似文献

Abstract

The cordiform projection employed by Oronce Fine, Gerard Mercator and Abraham Ortelius may have had a hermetic meaning. The focus in this paper is on Ortelius, for recent studies have suggested connections between Ortelius, Christopher Plantin and a clandestine religious sect in Antwerp, called the Family of Love (Family of Charity), whose emblem was the heart, source of divine illumination and of Free Will. It is argued that Ortelius's contemporaries in the radical religious circles of northern Europe would have perceived the Theatrum orbis terrarum in such a light. As Guillaume Postel's evaluation of Ortelius's work demonstrates, the atlas was considered a talismanic book based on the power of the images.  相似文献

In this article, which is part of a series on national atlases, the author makes recommendations for the selection of maps and map content to be incorporated into the atlas section devoted to the water resources of the land. She divides the maps into two major classes: maps of drainage patterns, and maps of the characteristics of stream regime.  相似文献

The complexity of binary maps that is provided by the areal arrangement of colors is considered, and measured using information theory. In addition, information theory provides other measures that have an interpretation in a map context. One of these, redundancy, is examined and found to bear a striking empirical relationship to a spatial autocorrelation statistic. It is argued that spatial autocorrelation is, conceptually as well as empirically, the two-dimensional equivalent of redundancy. It too measures the extent to which the occurrence of an event (color) in an areal unit constrains, or makes more probable, the occurrence of an event in a neighboring areal unit.  相似文献

Maps have been compiled for the zonal and meridional components of the resultant velocities of upper air currents in January and July. The principal features of these maps are described and analyzed, and the winter and summer situations of the Northern and Southern Hemispheres are compared.  相似文献

Abstract

To be coherent and effective, teaching programmes require broad integrating concepts. Such paradigms of modern geography as quantification, behaviouralism, Marxism, and systems theory are discussed as a guide to finding these concepts. Any frameworks that are adopted must recognise the dualism between methodological and theoretical concepts.  相似文献

A comparison of United States topographic maps with the actual terrain shows a disregard of geographical differences in the use of vegetation symbols, contour lines and population centers. This is attributed to the fact that topographic technicians lack a geographic background. The county soil surveys of the United States evoke a great deal of admiration and praise, but the lack of a uniform soil classification enabling the compilation of generalized soil maps is deplored.  相似文献

Many Western universities are responding to the demands of globalisation by attempting to internationalise their curricula—that is, to introduce an element of multiculturalism. This project derives its rationale from three assumptions: (1) the globalisation process is a viable agenda for a sustainable and just future for all people; (2) it is the responsibility of the university to respond faithfully to current demands of Western society—that is, in this case, to the demands of globalisation; and, (3) given the first two assumptions, internationalisation of the curriculum is a logical response. It is argued that the first two assumptions need to be explicitly recognised and then rigorously questioned. This must be done by academics themselves, and as a joint project with students in the classroom. This questioning amounts to challenging the foundational concepts of contemporary Western civilisation. New directions for the future may thus emerge from the classroom. The core concepts of other cultures may be seen as an asset in this process, giving an entirely new meaning to the term ‘internationalisation of the curriculum’.  相似文献

Public policy scholars have developed a number of theories of the policymaking process. Their work has come to define what some now refer to as the "policy theory" literature. Our task is to identify theoretical and empirical courses of study that will advance this research program. We limit ourselves to identifying an existing theory that already provides such an advance and discuss some of its theoretical benefits and empirical support. Specifically, we make the case that there exists a well-developed theory of delegation that rivals what we deem to be the best of the existing policy theories. We also suggest that existing theoretical frameworks might benefit from incorporating delegation theory explicitly and conclude that policy research has much to contribute to the development and useful application of delegation models.  相似文献

The basic problem of statistical indicators of the degree of correspondence between geographic phenomena is that they are not sufficiently differentiated from place to place. There is a need for special maps of interrelations showing the correspondence of spatial distribution of two or more related phenomena. Five techniques are proposed: (1) The delimitation of regions distinguished by varying degrees of correspondence; (2) the compilation of cartograms of interrelations; (3) the compilation of maps of isocorrelates; (4) the compilation of maps of deviation from a regression; (5) the compilation of contour-entropy maps. The author thus expands on the 1957 paper of Robinson and Bryson on a method for describing quantitatively the correspondence of geographical distributions.  相似文献

Abstract

The primary objective of the article is to present the relief maps and models of Palestine, Jerusalem and some historical monuments, which are kept in the PEF Archives in London. We will describe each of these objects, try to identify its date, maker, and circumstances of its making. We will present them according to the site represented in them, but suggest also classifying them as (a) artifacts brought as souvenirs from Jerusalem; (b) models and relief maps created by the Fund and its members as a product of their scientific endeavours; and (c) models and relief maps created by scholars who were not directly connected with the PEF.  相似文献

While the history of cartography has freed itself from debilitating debates over the scientific and artistic status of maps, considerations of the relationship between art and cartography have continued to focus largely on pre‐modern maps, avoiding critical examination of twentieth‐century art and science in cartography and leaving intact the impression that these followed distinct paths in the modern period. In this paper, however, I have drawn on theoretical work in Science Studies and taken account of modern art's separation from aesthetics to suggest that an examination of art and cartography in the twentieth century should focus on mapping practices rather than on maps as such. A summary overview of modern‐art movements and selected works indicates a continued, if critical, engagement of avant‐garde artists with cartography, and the examination of more popular newspaper artwork produced in the context of the intensely modern visual culture of mid‐twentieth century Los Angeles indicates a similarly close connection between modernity, art and cartography.  相似文献

Traditional approaches to intrasite spatial analysis in archaeology have concentrated on identifying associations among classes of artifacts over a site surface. This focus has tended to ignore the possible effects of contextual constraints on inter-class relationships, for example the “gravity effects” of hearth features on object deposition. Consequently, sets of co-occurring artifact classes defined in space are usually ascribed behavioural significance as “tool kits”, even though they may represent unrelated objects simply discarded into the same spatial location. This paper attempts to illustrate this problem through contextual integration of artifact and feature distributions. Quantitative methods are employed to carry out contextual spatial analysis of artifact distributions from the Upper Palaeolithic rockshelter site Le Flageolet I (Dordogne, France). Results indicate that associations among artifact classes in space might be constrained by feature locations at Le Flageolet I and that contextual interpretations are warranted for the observed inter-class relations.  相似文献
