Aerial photographs have been widely adopted in geology, physical geography, agriculture, soil conservation, and forestry, but it is surprising to find how rarely they have been thoroughly exploited in archaeology. This may be due to the fact that most of the literature dealing with the subject of aerial photographs and their uses has been directed to other fields, with very little appearing in archaeological literature. Possibly the earliest use of aerial photographs in archaeology is discussed in Crawford's Wessex from the Air (1928), while Reeves's “Aerial Photography and Archaeology” (1936), was probably the first work directed specifically to the American archaeologist. Both works deal more with locating sites from the air and taking aerial pictures of them than with aspects of mapping from aerial photographs or their use in reconnaissance work.

Abstract A prediction system was developed that estimated pine density and hardwood competition levels in young plantations using simple measurements made on 35mm aerial photographs. The precision of the prediction system was found to be moderate to good. The use of these photo-based modelsin a decision-making situation was examined. Ground-based decisions regarding replanting, spraying for competition control, or no treatment were compared to similar decisions reached strictly from the aerial photographic measurements. Approximately 80% of all decisions agreed, and 90% of theno-treatment decisions agreed. While aerial photographs do not totally eliminate the need for field work, it is clear that photographic information can often produce reliable decisions with reduced field efforts. South. J. Appl.

Abstract. Images are visually inspected for defects that affect downstream operations and qualitatively evaluated immediately after they are acquired. Therefore, there is concern that an increase in the number of images taken affects the quality and process of inspections. Among the defects qualitatively detected in visual inspections, blurring is a serious one, despite its low rate of appearance. However, the blurry images detected in the visual inspections can only be solved by the take another photograph. For this reason, it is not acceptable for any blurry images to be missed in the visual inspections. Therefore, quantitative evaluations are an issue when inspecting photographed images. In the present study, its characteristics in aerial photography were investigated and it was established that motion blur occurs in aerial photography. The motion blur is a condition in which the subject appears to have drifted. We focused on the gradient direction of the image, which is considered to be concentrated in a certain direction. The concept of directional statistics was used to statistically process the gradient direction. The evaluation values calculated from the gradient direction statistics tended to increase with the amount of blurring in the aerial photographs. An experiment was conducted to investigate whether images with blurring could be detected in a large number of aerial photographs. As a result, we were able to successfully detect blurred images that had been overlooked during the visual inspection as well as the images that had been previously detected during the visual inspection.

The tropical seasonal rainy evergreen broad-leaved forest vegetation of the Cucphoung National Park has been classified and the distribution of plant communities has been shown on the map using the relations of vegetation to geology, geomorphology and pedology. The method of vegetation mapping includes: 1) the identifying of vegetation types in the remote-sensed materials (aerial photographs and satellite images); 2) field work to compile the interpretation keys and to characterize all the communities of a study area; 3) compilation of the final vegetation map using the combined information. In the classification presented a number of different level vegetation units have been identified: formation classes (3), formation sub-classes (3), formation groups (3), formations (4), subformations (10) and communities (19). Communities have been taken as mapping units. So in the vegetation map of the National Park 19 vegetation categories has been shown altogether, among them 13 are natural primary communities, and 6 are the secondary, anthropogenic ones. The secondary succession goes through 3 main stages: grassland herbaceous xerophytic vegetation, xerophytic scrub, dense forest.

Resumo: Há um relativo depauperamento no tocante ao nosso conhecimento a respeito da relação entre a filosofia kantiana e a constituição da geografia moderna e, conseqüentemente, científica. Esta relação, quando abordada, o é - vezes sem conta - de modo oblíquo ou tangencial, isto é, ela resta quase que exclusivamente confinada ao ato de noticiar que Kant ofereceu, por aproximadamente quatro décadas, cursos de Geografia Física em Königsberg, ou que ele foi o primeiro filósofo a inserir esta disciplina na Universidade, antes mesmo da criação da cátedra de Geografia em Berlim, em 1820, por Karl Ritter. Não ultrapassar a pueril divulgação deste ato em si mesma só nos faz jogar uma cortina sobre a ausência de um discernimento maior acerca do tributo de Kant àfundamentação epistêmica da geografia moderna e científica. Abrir umafrincha nesta cortina denota, necessariamente, elucidar o papel e o lugardo “Curso de Geografia Física” no corpus da filosofia transcendental kantiana. Assim sendo, partimos da conjectura de que a “Geografia Física” continuamente se mostrou, a Kant, como um conhecimento portador de um desmedido sentido filosófico, já que ela lhe denotava a própria possibilidade de empiricização de sua filosofia. Logo, a Geografia Física seria, para Kant, o embasamento empírico de suas reflexões filosóficas, pois ela lhe comunicava a empiricidade da invenção do mundo; ela lhe outorgava a construção metafísica da “superfície da Terra”. Destarte, da mesma maneira que a Geografia, em sua superfície geral, conferiu uma espécie de atributo científico à validação do empírico da Modernidade (desde os idos do século XVI), a Geografia Física apresentou-se como o sustentáculo empírico da reflexão filosófica kantiana acerca da “metafísica da natureza” e da “metafísica do mundo”.THE COURSE OF PHYSICAL GEOGRAPHY OF IMMANUEL KANT(1724-1804): CONTRIBUTION FOR THE GEOGRAPHICALSCIENCE HISTORY AND EPISTEMOLOGYAbstract: There is a relative weakness about our knowledge concerningKant philosophy and the constitution of modern geography and,consequently, scientific geography. That relation, whenever studied,happens – several times – in an oblique or tangential way, what means thatit lies almost exclusively confined in the act of notifying that Kant offered,for approximately four decades, “Physical Geography” courses inKonigsberg, or that he was the first philosopher teaching the subject at anyCollege, even before the creation of Geography chair in Berlin, in 1820, byKarl Ritter. Not overcoming the early spread of that act itself only made usthrow a curtain over the absence of a major understanding about Kant’stribute to epistemic justification of modern and scientific geography. Toopen a breach in this curtain indicates, necessarily, to lighten the role andplace of Physical Geography Course inside Kantian transcendentalphilosophy. So, we began from the conjecture that Physical Geography hasalways shown, by Kant, as a knowledge carrier of an unmeasuredphilosophic sense, once it showed the possibility of empiricization of hisphilosophy. Therefore, a Physical Geography would be, for Kant, theempirics basis of his philosophic thoughts, because it communicates theempiria of the world invention; it has made him to build metaphysically the“Earth’s surface”. In the same way, Geography, in its general surface, hasgiven a particular tribute to the empiric validation of Modernity (since the16th century), Physical Geography introduced itself as an empiric basis toKantian philosophical reflection about “nature’s metaphysics” and the“world metaphysics” as well.Keywords: History and Epistemology of Geography, Physical Geography,Cosmology, Kantian Transcendental Philosophy, Nature.

In the summer of 1872 I visited Norway, and wrote the following brief notice of certain high-level terraces immediately on my return to England, but kept it back that I might first consult some papers on Norwegian terraces that had appeared in the closing numbers of “Scientific Opinion”; these I was not able to meet with for so long a time that I gave up the idea of sending my notice to the press. I am now induced to do so, because I see that the subject of the parallel roads of Glenroy still occupies the attention of geologists, and it may induce some one next summer to examine minutely the Dovre terraces and sand-heaps and their relation to the physical geography of the district. I was merely able to make a flying visit to them, which I delayed my party to do, because they caught my eye so forcibly, as we were driving along the valley.

This study aimed to map phytophysiognomies of an area of Ombrophilous Dense Forest at Parque Estadual da Serra do Mar and characterize their floristic composition. Photointerpretation of aerial photographs in scale of 1:35,000 was realized in association with field work. Thirteen physiognomies were mapped and they were classified as Montane Ombrophilous Dense Forest, Alluvial Ombrophilous Dense Forest or Secondary System. Three physiognomies identified at Casa de Pedra streamlet's basin were studied with more details. Riparian forest (RF), valley forest (VF), and hill forest (HF) presented some floristic distinction, as confirmed by Detrended Correspondence Analysis (DCA) and Indicator Species Analysis (ISA) conducted here. Anthropic or natural disturbances and heterogeneity of environmental conditions may be the causes of physiognomic variation in the vegetation of the region. The results presented here may be useful to decisions related to management and conservation of Núcleo Santa Virgínia forests, in general.

The most enigmatic problems with the nearly 200 salt domes pierced in the Persian Gulf and in the Zagros Mountain Ranges (ZMR) in southern Iran, a unique morphology in the world, have been the matter of this study, which is based on a combination of field work, enhancement of satellite and aerial photographs etc. In the ZMR, structural anomalies are frequently associated with similar facies distribution patterns. In the eastern portion of the region, emergent salt plugs of Infra-Cambrian age exhibit the same alignment patterns. Such trends bear no apparent genetic relationship to the Tertiary folding responsible for the present Zagros fold belt, but rather indicate their affinity with linear basement features which are readily observable on Land sat imagery and aerial photographs. Bending of anticlines in the competent cover rock, combined with minor strike-slip faults and horizontal displacements of parts of folded structures, strongly point to the presence of these basement faults. The salt plugs, which have pierced cover rocks of up to 10000 m thick, are distributed on the Arabian Platform along regional basement faults. The area of diapir outcrops is bounded by the Oman Line to the east and by the Kazerun fault to the west. Pieces of the basement have been brought up to the surface on some of the salt domes. The fragments were transported by rotational ascent of the Hormuz Salt Formation to the present and former land surfaces. The recognition of features related to basement tectonics and realization of their implication in the control and modification of geological processes are important adjuncts to the search for hydrocarbon accumulations in this region. To our best knowledge, data of basement faults in the study area are scarce. Therefore, this study was carried out to determine basement faults and their relation to salt dome distribution. Considering the fold axes bending, the trend of the salt plugs and also the distribution of epicenters of the last century, n umerous new basement faults are introduced in this paper.

In the 1940s and 50s Mr Eric Bradley, a flying instructor at Scone, noticed and described a series of crop-marks to the W of Perth during attempts to trace the Roman road, from the Gask Ridge, at its last known point near Dupplin Lake some 8-5 km to the SW of the fort at Bertha. In 1969 Dr J X W P Corcoran admirably summarized the evidence available from Mr Bradley's notes and maps, Cambridge University Committee for Aerial Photography (CUCAP) photographs and RAF vertical photographs in an unpublished note, now in the NMRS. In 1967 a valuable series of aerial photographs of the Huntingtower sites was taken by John Dewar Studios for the Inspectorate of Ancient Monuments. Subsequently RCAHMS has photographed the area resulting in the discovery of further features.

Considering the interest that has been awakened of late in the Bagshot Beds of the London Basin, and the paucity of good sections open to the light of day exhibiting any considerable vertical range of those beds, it has occurred to me that a fuller description of these Finchampstead sections may be of sufficient interest to students of Tertiary geology to justify its appearance in the pages of the Geological Magazine. In the task we have before us of attempting to workout the old physical geography of the Lower Thames Basin in later Eocene times, every contribution of facts (by no means the easiest part of inductive science) must be welcome to students of the subject. The problem was sketched in its outlines and bequeathed to his successors by the versatile mind of the late Prof. John Phillips, F.R.S. “In considering these remarkable strata (he says, of the London Bagshot Beds), which were accumulated in a period so near, geologically speaking, to our own, we are presented with problems of great interest, which, if they can be solved, will have more than local application.
