The Geography Lesson: photographs and the construction of imaginative geographies
a new means of acquiring, ordering and disseminating geographical information. The work of traveller-photographers is used to show how the views were employed to provide visual access to sites of travel. The historicity of photographic practice
An 1851 stereoscopic daguerreotype (The Geography Lesson) frames this exploration of photography, travel and geography in the mid-nineteenth century. At a time when travel was embraced as a way of seeing and knowing the world, photographs offered
Digital Photographic Archives for Environmental and Historical Studies : An Example from Ethiopia

Here the AA. demonstrate how historicalphotographs (1868, 1895, 1907, 1936) in Ethiopia are used in studies on landscape and land use changes, soil erosion and geomorphology, history and historical context, livelihood and archaeology. Further
, using the case study of Ethiopia, the location, accessibility and quality of digital archives of historicalphotographs is discussed as well as the way in which they can be used in research (comparison with actual photographs). Historical landscape
photographs that are available in major archives may now largely be traced and often obtained through the Internet, as libraries increasingly are digitising collections and making them available online.
The retreat of Tien Shan glaciers (Kyrgyzstan) since the Little Ice Age estimated from aerial photographs, lichenometric and historical data

The retreat of 293 glaciers in the Tien Shan Mountains from their maximum extent during the Little Ice Age (LIA) is estimated using aerial photographs from 1980 to 1985 and maps at a scale of 1:25 000, constructed during period 1956-1990. Two
indices of changes are used : the linear distance from the glacier terminus to its Little Ice Age moraine and the difference in absolute elevation of the terminus and the moraine. Historical information about the front positions of glaciers in the 1880s
Effects of historical land use on sediment yield from a lacustrine watershed in central Chile
Sediment yield in the San Pedro Lake watershed, inferred from sedimentation in the lake, can be related to land use changes shown on aerial photographs taken during the period 1943-1994. To study effects of these changes, the AA. took a core from
the centre of the lake and estimated sedimentation rates by Pb 210 dating, which they checked with Cs 137 and pine pollen. Sediment yield between 1955 and 1994 closely tracks the total land use change that can be detected on sets of aerial photographs
. However, this measure of land use change may be unreliable because it probably excludes many changes that occurred in long intervals between successive photographs.

The use of historical data and artifacts in geomorphology
Aerial photography ; Archaeology ; Climatic data ; Geomorphology ; Historical geography ; Hydraulic works ; Land use ; Litter ; Topographic map
Investigations in geomorphology and environmental management can be greatly enhanced by the use of of historical techniques. The approach is useful for tracing human-induced changes as well as for those occurring naturally. Several primary
techniques are introduced in this essay : Instrumented topographic surveys; Stream and sediment discharge records; Permanent landscape features; Land (cadastral) surveys; Aerial photographs; Ground-based oblique photography; Litter; Contemporary descriptions
The historical progress of the evolution of lake Tung-ting.
Examination of historical records, geological and archaeological literature, and satellite photographs provides an evolutionary picture of Tung-ting lake outlined with the aid of 7 maps in series. Variations in the water surface area, ascribed
to uplifts and down warping, are traced through the incipient stages, the neolithic and historic dynasties. Accelerated silting since the 19th century causes reduction in the size of the lake to about half its maximum. The extent of silting in the last 30
Using a historical aerial photograph analysis to inform trout habitat restoration efforts
Restoration of the upper Strawberry River included bank stabilization techniques because it was assumed that excessive bank erosion was degrading spawning habitat for Bonneville cutthroat trout (BCT). Using a long-term aerial photograph record
, the historical range of variability in bank erosion rates and channel geometry was determined. Although a historical loss of riparian vegetation coincided with a shift to a wider and more sinuous channel, lateral migration rates declined and the channel narrowed
. The results highlight how a historical analysis can be used to identify the sources of habitat degradation and inform the selection of restoration goals and strategies.
During the First World War a major turning-point in the history of cartography was made in Palestine. Town maps for the Palestine Front were an immediate necessity. The photographs and maps produced then by the British Forces are excellent
historical documents, particularly because of their high quality and preservation.
A summary and review of the work accomplished by the I.G.U. Commission on the Coastal Environment 1972-1984 under the chairmanship of the author. Problems of documenting and measuring coastline changes, comparing historical descriptions, maps, air
photographs, and nautical charts with the present morphology. Selective review of evidence for various kinds of coastline change around the world, starting with Alaska and circumnavigating land areas counter-clockwise. Categories of coastline change identified
On the basis of reported archaeological findings, old cartography (available from XVI century), air photographs and other means of historical documentation, an attempt is made to outline coastal variations in the Po delta for the last 25 centuries
Spatially variable historical alluviation and channel incision in west-central Wisconsin
This study employs data from valley-bottom surveys, coring investigations, topographic maps, and aerial photographs to identify and explain spatial variations in historical alluviation along tributary streams in the Buffalo River watershed
, an agricultural watershed in west-central Wisconsin. Similar to findings from other agricultural watersheds, the spatial distribution of historical alluvium in the Buffalo watershed reflects the controlling influence of watershed size and valley-bottom width
. An additional significant factor that has affected valley-bottom sedimentation is historical channel incision.

ER MAPPER TM, an image processing system, was used to manipulate scanned maps, plans and aerial photographs to enable detailed analysis of historical river channel planform change. It offers the opportunity to spatially reference each item
, and the advantages of the package and the limitations of the historical database are also outlined.

The purpose of this paper is to reconstruct the Holocene evolution of the digitate fluvial delta on Middle Creek, Narrabeen Lagoon, NSW. Therefore the landforms of the delta plain were mapped, historic delta changes were determined
by photogrametrically comparing 1951 and 1994 vertical air photographs, and the lithofacies of the delta plain were constructed from shallow hand-auger holes and deep boreholes.
