The alpine landscape is rugged, dominated by glacial morphogenesis, comprising specific landforms of different sizes and shapes with a marked vertical relief and hierarchical-ordering of the forms. Digital geomorphometric analyses of such a land surface in a high...

SRTM1 Digital Elevation Model for many mountain ranges in Romania were processed to provide slope gradient distributions for each 50 m band of altitude. The effects of cirques are seen in an increase in standard deviation of gradient, and a spread in all percentiles,...

Area is an integral part of any spatial database and has a significant role in many geographic analyses and applications. Planar algorithms that are widely used to calculate area ignore the slope and curvature of the terrain and result in under-estimation, particularly...

We present an improvement of image classification by “thresholding”, using topographic information to determine multiple thresholds. We devised a two-steps procedure for automatic classification into landslide or no landslide categories of a change-detection map...
