Site Characterization Using Integrated Imaging Analysis Methods on Satellite Data of the Islamabad, Pakistan, Region [PDF]
, 2008 We develop an integrated digital imaging analysis approach to produce a first-approximation site characterization map for Islamabad, Pakistan, based on remote-sensing data. We apply both pixel-based and object-oriented digital imaging analysis methods to

The Impact of Acoustic Imaging Geometry on the Fidelity of Seabed Bathymetric Models [PDF]
, 2018 Attributes derived from digital bathymetric models (DBM) are a powerful means of analyzing seabed characteristics. Those models however are inherently constrained by the method of seabed sampling. Most bathymetric models are derived by collating a number

Automated unsupervised geomorphometric classification of earth surface for landslide susceptibility assessment [PDF]
, 2008 The aim of this work is to define an automated method of terrain classification in order to evaluate the correlation degree between topographic forms of the analyzed territory and registered landslide phenomena with a Landslide Inventory and DEMs as ...

Surface Roughness in Geomorphometry: From Basic Metrics Toward a Coherent Framework
Remote SensingSurface roughness (SR), most often computed from a digital elevation model (DEM), is a fundamental concept in geomorphometry, with significant applications across the earth sciences and ecology. However, its analysis remains fragmented, lacking a unified

Quantitative studies of the morphology of the south Poland using Relief Index (RI)
Open Geosciences, 2017 The aim of this study was to introduce a new morphometric index named Relief Index (RI). RI is the ratio of the total length of the contour lines and the surface area at which they occur.

Surface fitting in geomorphology - examples for regular-shaped volcanic landforms [PDF]
, 2014 In nature, several types of landforms have simple shapes: as they evolve they tend to take on an ideal, simple geometric form such as a cone, an ellipsoid or a paraboloid. Volcanic landforms are possibly the best examples of this ?ideal?
