  • from books, personal collections, and Internet auction sites. There was a disconnect between picture postcard and reality, and an increased importance of connotative signs unifying a homogenous Main Street ideal. Three distinct eras of manipulation
  • emerged from the data.

  • Satellite imageries from Landsat ETM+ and ERS (European Remote Sensing) Radar sensors, together with elevation data collected by the Shuttle Radar Topography Mission (SRTM) in addition to recent and older bibliography, have led to the hypothesis
  • that, before the Late Messinian drawdown of the Mediterranean Sea, the River Nile flowed into the Libyan palaeo-Sirt. The study is still in progress; in this paper data are presented from three areas, showing evidence of palaeo-drainage of Tortonian-Late

  • High spatial resolution data acquisition for the geosciences : kite aerial photography
  • This paper outlines an experiment to collect high spatial resolution stereo-imagery for the photogrammetric generation of DEMs as input to geomorphological process-based studies. The AA. used a kite platform as it remains comparatively inexpensive
  • , is extremely portable and can operate in a variety of environments. The research outputs are used to test the effectiveness of the methodology for providing low cost, high resolution data. The combination of kite and digital camera is more generally termed kite
  • aerial photography (KAP). The accuracy of data derived by digital photogrammetry and imagery acquired using a kite based non-metric camera is assessed by 3 experiments : one on smooth terrain, one on tor terrain and one on a glaciofluvial esker

  • The aim of the study is to develop a new method for the early night-time near-surface air temperature pattern estimation based on the surface temperature data in the urban area of Szeged (S-Hungary). The surface temperature data have been collected
  • by an airplane-based thermal infrared sensor at an altitude of 2000 m above ground level. The study area was covered by hundreds of images with a spatial resolution of about 2 m. The measured values were calibrated with data of in situ surface measurements

  • This paper concerns the latter aspects by providing morphological details and Schmidt hammer (rock hardness/weathering) data from a large rock slope failure at the mouth of Urdadalen, in the Jotunheimen. It is believed that this represents the first
  • with the potential to collect and retain snow that might, in future, lead to niche glacier development and cirque initiation, and to provide a large volume of rock debris for entrainment and onward transport in future glacial cycles.

  • . This paper presents the use of TLS as an alternative method for collecting high-resolution 3D data from fluvial gravel surfaces, enabling the development of grain-scale Digital Terrain Models (DTMs). Application to a coarse grained gravel system, the River
  • Terrestrial Laser Scanning (TLS) is a laser ranging technique, applying the same principles as airborne Lidar. It offers a new methodology for the rapid acquisition of high-resolution and high-precision surface elevation data from in situ sediments

  • The aim of this paper is to investigate the relationships and differences existing between the erosion rates in the coastal and terrestrial limestones through the comparison of micro-erosion meter (MEM) and traversing micro-rosion meter (t-MEM) data
  • collected over a maximum of 3 years in the Istrian coastal sector, 10 years in the Gulf of Trieste, 25 years in the Classical Karst and 5 years in the inland Istrian Karst. The sites and their distribution were chosen in order to get information

  • The AA. present here the first data on the seasonal variations of Pb, Cu, Zn, Co and Ba concentrations in the East Rongbuk Glacier which lies on the northern slope of Mt. Qomolangma, spanning from autumn 2005 to summer 2004. They were obtained
  • by analyzing a total of 18 samples collected from a snow pit dug in the East Rongbuk Glacier accumulation area. Seasonal variations of the concentrations and δO 18 are observed, of which Pb, Cu, Zn and Co are much lower in summer monsoon season than that in non
