Aerial photographs are used to develop a relationship between the number of debris slides generated during a hydrologic event and the size of the event, and the longterm average debris-slide frequency is calculated from climate records using the relation. For a site in California with an average of 8.3 slides km yr, a sequence of four photo sets (representing 10–15 years, 35–50 observed slides,...

Ongoing landscape transformation is one of the major causes behind disappearance of traditional landscapes, and lead to species and resource loss. Tree in paddy fields in the northeast of Thailand is one of those traditional landscapes. Using three different historical time layers, we acknowledged the severe deforestation and rapid urbanization happened in the region. Despite the general thinki...

The archaeologists have debated over a century and a half about the localization of the Aquileia theatre. Luisa Bertacchi places it as her latest proposal at the Fondo Comelli; however, no apparent traces of a theatre were found there. Some of its parts were obviously removed, but nothing remains of a large building which was still visible during the 13th and 14th centuries. Aerial photographs ...

This paper presents a method for extraction and recognition of trucks from aerial photographs. A new method, mean shift image segmentation, is employed to extract truck shadow and boundary information. After a conversion of the boundaries into vector data, an enclosing minimum area rectangle is fit to each boundary. These rectangles are input as candidates into a designed Hopfield Neural Networ...

The development of this article follows the search for a technique that automates the modelling and dynamics of any natural (dunes, slipping of mountainsides, glaciers...) or artificial (collapsing of buildings...) structure. In this study, the dynamics of the Argualas rock glacier (Pyrenees-Spain) has been investigated since 1991. A peculiarity of rocks glaciers is their sensitivity to environ...

Information on landslide displacement from SAR Interferometric Point Target Analysis (IPTA) and sketch maps from aerial photography interpretation are combined for the study of landslides in Ticino, Southern Switzerland. Numerous unstable phenomena are considered in this mountainous region, with an elevation range from approximately 200 m a.s.l. to more than 3000 m a.s.l. The results achieved w...

Mauro Agnoletti: Historical research and landscape analysis. The case of Tuscany (Italy) Between 1999 and 2002 a research project entitled “Analysis and Management of Forest and Rural Landscapes” has been carried out for the Tuscan Regional Government. One of the goals of the study was to asses a method in order to make historical investigation a necessary tool in planning and management of lan...

This paper analyzes the interactions between land use and forest cover in the Upper Midwest, USA from 1970 to 1990. New data are presented and interpreted to evaluate the effects of land-use changes, especially abandonment of agriculture and dispersed development, on forest cover throughout the region. Forest-cover data were collected from Landsat satellite imagery and land use was interpreted ...

In previous field seasons, we first mapped landscape features and archaeological sites using aerial photographs and then we identified, described, and interpreted in the field those features that were recognizable on the photographs. This procedure resulted in a series of maps detailing the archaeological landscape comprising settlement sites, ancient "hollow way" roads, canals, miscellaneous q...
