  • Remote sensing and geomorphometric discrimination of slope processes
  • The 2 objectives of this study are : expand the scope of geomorphometric analysis to include variables based on hillslope profile analysis, and show that a combined spectral, textural and geomorphometric data set can separate geomorphic surfaces
  • 1995
  • Toward geomorphometric models for estimating landslide dynamics and forecasting landslide occurence in Japanese mountains
  • This paper examines, first, physical properties of landslide materials and dynamics of landslide processes using such geomorphometric attributes as length of the landslide mass, the relative altitude and the area of the mass. Special attention
  • , which is expressed by the dispersion of altitude distributed over a specific square sample space, is a geomorphometric attribute that can now be calculated easily from DEMs.
  • 1995
  • Slope and aspects calculations on gridded digital elevation models : examples from a geomorphometric toolbox for personal computers
  • This paper discusses some results from analyses of slope and aspects computed with a geomorphometric program, MICRODEM. The results discussed here primarily deal with 2 digital elevation models (DEMs) produced by the U.S. Geological Survey, although
  • 1995
  • Geomorphometric measures for digital elevation models
  • Geomorphometric measures developed for contour maps are redefined here specifically for digital elevation models (DEMs). The measures are of 3 types depending on the feature localized : point, window, or drainage basin - the principal focus
  • 1995
  • The geomorphometric (catchment area, relative relief) and climatic parameters (mean annual precipitation, rainfall intensity) influencing drainage density are evaluated. - (JS)
  • 1995
  • Adaptive methods for the refinement of digital terrain models for geomorphometric applications
