Multi-scale digital terrain analysis and feature selection for digital soil mapping
Geoderma, 2010Abstract Terrain attributes are the most widely used predictors in digital soil mapping. Nevertheless, discussion of techniques for addressing scale issues and feature selection has been limited. Therefore, we provide a framework for incorporating multi-scale concepts into digital soil mapping and for evaluating these scale effects. Furthermore, soil

The recent advancement in digital terrain analysis and modeling
International Journal of Geographical Information Science, 2013Terrain analysis (or geomorphometry) is ‘the science of quantitative land-surface analysis’ (cited in Pike et al. (2009, p. 3)).

Digital photogrammetric analysis approaches for the realization of detailed terrain models
Rendiconti Online della Società Geologica Italiana, 2020Digital Surface Models (DSMs) with a high spatial resolution and accuracy are of increasing importance for many applications. Recent advances in data acquisition technologies, such as those related to the use of Unmanned Aerial Vehicles (UAVs), enabled the acquisition of images suitable to generate high-resolution DSMs.

Circular sampling for Fourier analysis of digital terrain data
International Journal of Rock Mechanics and Mining Sciences & Geomechanics Abstracts, 1989Description of the variance structure of soil properties by computation of a Fourier spectrum requires considerable attention to the procedure and methods necessary to fit requirements of the discrete Fourier transformation process. Two schemes for space sampling are compared and evaluated.

Multi-Scale Digital Terrain Modelling and Analysis
2008Scale is one of the most important but unsolved issues in various scientific disciplines. This chapter tackles systematically the issues related to scale in terrain modelling and analysis. It starts with some discussions on the notions of scale and multi-scale. Then three approaches for the multi-scale representation of terrain surface are presented, i.

Applications of Digital Terrain Data to Multisensor Image Analysis: ABSTRACT
AAPG Bulletin, 1985Some of the key factors for detection of facies changes in sedimentary environments, such as changes in surface composition and texture, are parameters that can be detected using the remote sensing techniques presently available. For example, multipolarization aircraft synthetic aperture radar (SAR), Landsat 4 Thematic Mapper (TM), and airborne Thermal

Digital Terrain Analysis in a GIS Environment. Concepts and Development
2007Digital models of topographic elevation data form an integral part of geographic information systems (GIS) and are most often used for (1) hydrological modelling including flood simulation, delineation and analysis of watersheds and drainage networks, (2) soil erosion and sediment transport modelling, (3) delineation and study of physiographic units ...
