Download or read book An Approach to Automated Terrain Classification from Digital Elevation Model written by and published by . This book was released on 1992 with total page 11 pages. Available in PDF, EPUB and Kindle. Book excerpt: Using digital elevation model data, landforms are classified into two broad, generic terrain features -- mounts and non-mounts. Mount represents an aggregation of elevated features including hills, mountains and ranges. All remaining features are classified collectively as non-mount. The results of this work suggest that it may be possible to acceptably replicate the manual classification of certain generic terrain features. However, the general utility of the mount/non-mount classification appears to be limited by the classification algorithms, the nature of the regional terrain and the quality of available digital data. Possible applications for generic terrain feature information, such as mounts and non-mounts, are presented.

Book excerpt: Dieses Buch untersucht, welchen Einfluß Landschaftsformen, insbesondere Höhenunterschiede, auf die an der Erdoberfläche ablaufenden Prozesse haben. Wasserbewegungen, die Sonneneinstrahlung sowie die Bodenentwicklung und -erosion werden alle mehr oder minder durch die Form der Landschaftsoberfläche gesteuert. Die Anwendungsmöglichkeiten der Landschaftsanalyse sind vielfältig: Sie reichen von Studien über Wasserscheiden und Feuchtgebiete über Bodenkunde und Erosionsstudien, Landschafts- und Landnutzungsstudien bis zu geomorphologischer Forschung und regionalen und globalen Ökologiestudien. Darüber hinaus kann die Landschaftsanalyse auch zu meteorologischen Vorhersagen sowie bei Problemen mit TV- oder Radiosignalempfang eingesetzt werden. Dieses Forschungsgebiet hat in Verbindung mit den jüngsten Fortschritten auf dem Gebiet der GIS und GPS eine rasante Entwicklung durchlaufen. In diesem Band werden alle diese neuen Ansätze und Anwendungsbereiche umfassend erläutert. (y05/00)
Download or read book Raster Least Cost Approach for Automated Corridor Alignment in Undulated Terrain written by Kumar R. Rao and published by . This book was released on 2020 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: A raster based route alignment using multi criteria factors created as raster layers is useful for evolving total cost raster layer utilized at different stages for multi-criteria decision analysis (MCDA). The integration of least cost path algorithm into the 3-D view of the terrain or false color composite Remote sensing data can give value addition in planning process and formulation of action plans. The designing of optimum route alignment depends upon the number of factor considered in the process of corridor analysis model for finding the optimum route for alignment to ensure designing of the road from source to a destination within two specified end point locations. The raster data layer on land use and land cover type can be prepared for generating relative cost layer using the image classification algorithms and the slope raster layer can be obtained from the digital Elevation Model. The optimum route has the least cost and it can incorporate parameters on environmental, technical, social, and economic issues. The raster corridor analysis has been implemented to design optimum route alignment between two locations in the Himalayan region of India to consider the suitability of the technique for hill road construction. The details of the same are given in the paper.

Book excerpt: Geomorphometry is the science of quantitative land-surface analysis. It draws upon mathematical, statistical, and image-processing techniques to quantify the shape of earth's topography at various spatial scales. The focus of geomorphometry is the calculation of surface-form measures (land-surface parameters) and features (objects), which may be used to improve the mapping and modelling of landforms to assist in the evaluation of soils, vegetation, land use, natural hazards, and other information. This book provides a practical guide to preparing Digital Elevation Models (DEM) for analysis and extracting land-surface parameters and objects from DEMs through a variety of software. It further offers detailed instructions on applying parameters and objects in soil, agricultural, environmental and earth sciences. This is a manual of state-of-the-art methods to serve the various researchers who use geomorphometry. Soil scientists will use this book to further learn the methods for classifying and measuring the chemical, biological, and fertility properties of soils and gain a further understaing of the role of soil as a natural resource. Geologists will find value in the instruction this book provides for measuring the physical features of the soil such as elevation, porosity, and structure which geologists use to predict natural disasters such as earthquakes, volcanoes, and flooding. * Technical details on a variety of software packages allow researchers to solve real-life mapping issues * Provides soil and agronomy researchers best practice techniques for soil data analysis to assist in enhanced land-use and planning * Offers geologists essential tactics for better environmental management by providing a comprehensive analysis of the physical features of soil * Companion website includes access to the latest technological advancements previously unpublished in any other comprehensive source: geomorphometry software, DEM data sources, and applications

This book was released on 2001 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: "This thesis is an exploratory analysis of automated mapping protocols that can be used to support Terrestrial Ecosystem Mapping and Predictive Ecosystem Mapping in British Columbia. This thesis employs neighbourhood analysis of elevation and its derivatives to discriminate the bioterrain elements defined by Terrestrial Ecosystem Mapping standards. In achieving these standards, discrimination beyond the basic topographic forms presented in current research is explored. The method developed strives to be - easily implemented by mapping projects employing standard GIS software ; flexible so that the extracted topographic forms can be tailored to varying project objectives ; compatible with the hierarchical procedure employed in Terrestrial Ecosystem Mapping ; efficient and accurate in that the process is advantageous over manual mapping methods. The effect of data quality is addressed through an assessment of DEM data interpolation techniques and classification accuracy. Random and systematic artifacts of the DEM that influence the quality of the derivatives are explored. The issue of scale-dependent shape is addressed by the constraints of objective-based mapping in which a map scale is specified and the most basic shape elements are aggregated into contiguous classes by a roving neighbourhood window. The results indicate that basic topographic elements are mapable from relief as well as first and second order elevation derivatives. These results give preliminary accuracy of 80% based on the three classes tested. The procedure requires decisions at every step, but it is felt that this complements the traditional mapping process in that it is hierarchical, and requires a synthesis of extensive knowledge of vegetation and landscape across many scales. Key Words: elevation, digital elevation model, topography, slope, aspect, curvature, Terrestrial Ecosystem Mapping, Predictive Ecosystem Mapping, scale, random, systematic error."--Page iv.
