Data acquisition artefacts are commonly found in multibeam bathymetric data, but their effects on mapping methodologies using geographic information system techniques have not been widely explored. Artefacts have been extensively studied in terrestrial settings, but their study in a marine context has currently been limited to engineering and surveying

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.

Using digital terrain analysis modeling techniques for the parameterization of a hydrologic model
Environmental Modelling & Software, 2002Abstract This paper discusses the application of digital terrain analysis modeling techniques to the parameterization of a semi-distributed hydrologic model. Most current techniques for deriving physiographic parameters in watershed analyses, including those using commercial geographic information systems (GIS), are tedious, costly and time consuming.

Research on the Fast Parallel Recomputing for Parallel Digital Terrain Analysis
2015With the rapid increasing of spatial data resolution, the high volume datasets make the geocomputation become more time-consuming especially operating some complex algorithms, i.e. viewshed analysis and drainage network extraction. Parallel computing is regarded as an efficient solution by utilizing more computing resource, which has also been proved ...

Filtering of digital terrain models by 2D Singular Spectrum Analysis [PDF]
, 2007 Singular Spectrum Analysis (SSA) has been approved as a model-free technique to analyse time series. SSA can solve different problems such as decomposition into a sum of trend, periodicities, and noise, smoothing, and others. In this paper, we validate abilities of 2D-SSA (the extension of SSA to analyse two-dimensional scalar fields) to treat digital ...

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.

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 ...
