  • Targeting the collection of superior data for the estimation of the intermediate deliveries in regional input-output tables
  • Evaluation de six méthodes de collecte de données dites supérieures en simulant l'estimation des matrices régionales de livraisons intermédiaires pour chacune des 27 provinces chinoises en 2002, sur la base de leurs matrices pour 1997. Les vraies

  • An analysis of the statistical distribution of event soil loss was carried out using the data collected in the period 1999–2008 at the microplots and plots of the Sparacia experimental area (Sicily, Italy). In particular, the theoretical probability
  • distribution reproducing the empirical frequency distribution of measured soil loss was established. An estimating criterion of the soil loss of a given return period was then developed. Finally, the frequency distributions of soil erosion data collected

  • linkages and development of appropriate sampling protocols. To make these comparisons, the AA. combine high-resolution, basin-extent data from field work and remote sensing with cross-scale graphical visualizations. The Nueces data (Texas) were collected
  • with remote sensing methods and the Yellowstone data were collected through extensive field surveys.
  • This article explores how multi-scalar data can be used to visualize and test the performance of different river models at different scales. In turn, departures from the models are explored as a mechanism for guiding future work on process form

  • Mapping hydraulic biotopes using terrestrial laser scan data of water surface properties
  • was collected using a terrestrial laser scanner (TLS) and hydraulic variability simply expressed through assigning a local standard deviation value to a set of adjacent water surface values. Statistical linkage of these data with biotope locations defined
  • This paper takes an innovative approach to biotope definition using high resolution spatial data to define water surface roughness for two representative reaches of the River South Tyne, Cumbria, and the River Rede, Northumberland, UK. Data
  • visually in the field allowed complete mapping of the surveyed reach defining habitat and biotope areas to the fine scale resolution of the TLS data.

  • of the public transport department. Based on multiple queries, the authors collect connection data – such as travel time – regarding one or multiple specific interesting locations. - (IfL)
  • The article deals with the public transport (ÖPNV), the connection planner, the accessibility map and the quality of mobility. In the approach, the AA. suggest to create an accessibility map for the city based on data from a connection planner

  • Clayey silts involved in a landslide have been sampled to study the role of sediment composition in developing sliding surfaces. Five drillings enabled the collection of 46 samples and to define active slide surfaces and non-active surfaces
  • (discontinuities). Results and discussion about the granulometrical, chemical and mineralogical data. Scanning electron microscopy demonstrated that active slide surfaces have an open texture, clay minerals are impoverished and non-oriented, whereas secondary

  • , besides the limits and applicability of the method, are discussed. The AA. have tested the RRS method in the Gulf of Trieste, on a micro-tidal rock coast, collecting data from 7 stations.
  • . The RRS method allows to use the traversing micro erosion meter (TMEM) on vertical rock surfaces, temporarily removing the slab from the operating position, so that measurements can be collected horizontally. Sources of errors and preliminary results
