Download or read book Predictive Soil Mapping with R written by Tomislav Hengl and published by Lulu.com. This book was released on 2019-02-16 with total page 372 pages. Available in PDF, EPUB and Kindle. Book excerpt: Predictive Soil Mapping (PSM) is based on applying statistical and/or machine learning techniques to fit models for the purpose of producing spatial and/or spatiotemporal predictions of soil variables i.e. maps of soil properties and classes at different resolutions. It is a multidisciplinary field combining statistics, data science, soil science, physical geography, remote sensing, geoinformation science and a number of other sciences. Predictive Soil Mapping with R is about understanding the main concepts behind soil mapping, mastering R packages that can be used to produce high quality soil maps, and about optimizing all processes involved so that also the production costs can be reduced. The online version of the book is available at: https: //envirometrix.github.io/PredictiveSoilMapping/ Pull requests and general comments are welcome. These materials are based on technical tutorials initially developed by the ISRIC's Global Soil Information Facilities (GSIF) development team over the period 2014?2017

Available in PDF, EPUB and Kindle. Book excerpt: Soils of South Africa is the first book in seventy years that provides a comprehensive account of South African soils. The book arranges more than seventy soil forms into fourteen groups and then provides, for each group: • maps showing their distribution and abundance throughout South Africa • descriptions of morphological, chemical and physical properties • a detailed account of classification and its correlation with international systems • a discussion of soil genesis which includes a review of relevant research papers • appraisal of soil quality from a land use perspective as well as for its ecological significance • illustrative examples of soil profiles with analytical data and accompanying interpretations. There is also a fascinating account of the special relationship that exists between South African animals and soil environments. Soils of South Africa should interest students and researchers in the earth, environmental and biological sciences, as well as environmental practitioners, farmers, foresters and civil engineers.

Book excerpt: GlobalSoilMap: Basis of the global spatial soil information system contains contributions that were presented at the 1st GlobalSoilMap conference, held 7-9 October 2013 in Orléans, France. These contributions demonstrate the latest developments in the GlobalSoilMap project and digital soil mapping technology for which the ultimate aim is to produce a high resolution digital spatial soil information system of selected soil properties and their uncertainties for the entire world. GlobalSoilMap: Basis of the global spatial soil information system aims to stimulate capacity building and new incentives to develop full GlobalSoilMap products in all parts of the world.

Book excerpt: INTRODUCTION 'Data and information are essential building blocks of science. Many types of data, including extant historical data which have newly appreciated scientific importance for the analysis of changes over time, are not being used for research because they are not available in digital formats' (International Council for Science, 2004). Maps made in the past remain the backbone for present and future studies. Soil maps are resources for researchers in many fields apart from soil science; they are the source of databases, related to and dependent on soils, used to monitor land degradation and improvement, changes in land use and water resources, and to predict climatic and other environmental changes. Less and less new, fundamental soil data are being produced these days; the older data and information are being pumped around more and more. Therefore it is vital to preserve the older data (in this case maps) as they are building blocks of most current soil information. The user of present-day, derived information should have easy access to the source material, if only to assess the reliability of the derived material. But, in many countries, soil maps are being lost because of lack of proper attention to storage and retrieval, often compounded by a loss of institutions that have been responsible for the acquisition and maintenance of soil and land resources data. This problem is acute in developing and transitional countries where valuable data, currently only available on paper, must be digitized before they are lost forever. In Africa, though not only in Africa, this type of information is rapidly being lost; much is already lost. The digitization of the African maps will enable the African countries to recover and re-use their soil information. Translation of soil information from paper maps and reports into digital format is a prerequisite of the next step - the development of a digital information system on soil and terrain that may be drawn upon for manifold applications. BACKGROUND For some 40 years, ISRIC World Soil Information has been providing significant support to the international science community by collecting and archiving regional-, national- and global-scale maps of soils and land resources. Despite effective procedures for storage and maintenance, most organizations involved in archiving struggle to arrest the deterioration of paper maps and the quality of information they contain. Deterioration occurs for various reasons that include handling, transport, exposure to light, moisture and atmospheric pollution. Realizing the need to conserve the information on existing maps, which underpin the fast-developing thematic mapping strategies to support soil protection, the Institute of Environment and Sustainability (IES) in the European Commission (Italy) and ISRIC World Soil Information initiated the European Digital Archive of Soil Maps (EuDASM). The immediate objective is to transfer soil information into digital format, with the maximum resolution possible, to preserve the information of paper maps that are vulnerable to deterioration. Beyond data rescue, the archive is expected to develop into a common platform for storing soil maps from around the world and making the information readily accessible. Organisations that maintain soil map archives in paper form, and wishing to conserve this information by transferring it into digital form, are invited to join the EuDASM programme. The initiative for this programme was taken by Dr Luca Montanarella of the European Joint Research Centre and Dr Otto Spaargaren of ISRIC World Soil Information in October 2004. The first level success for this initiative was figured out by completion of the around 2000 soil maps pertaining to the African continent. Through this digitization programme the map quality and precision of information were preserved against further loss assuming to be required for future use by land resources specialists.
