Book excerpt: Signi?cant technological advances have been few and far between in the past approximately one hundred years of soil survey activities. Perhaps one of the most innovative techniques in the history of soil survey was the introduction of aerial photographs as base maps for ?eld mapping, which replaced the conventional base map laboriously prepared by planetable and alidade. Such a relatively simple idea by today’s standards revolutionized soil surveys by vastly increasing the accuracy and ef?ciently. Yet, even this innovative approach did not gain universal acceptance immediately and was hampered by a lack of aerial coverage of the world, funds to cover the costs, and in some cases a reluctance by some soil mappers and cartog- phers to change. Digital Soil Mapping (DSM), which is already being used and tested by groups of dedicated and innovative pedologists, is perhaps the next great advancement in delivering soil survey information. However, like many new technologies, it too has yet to gain universal acceptance and is hampered by ignorance on the part of some pedologists and other scientists. DSM is a spatial soil information system created by numerical models that - count for the spatial and temporal variations of soil properties based on soil - formation and related environmental variables (Lagacheric and McBratney, 2007).

Available in PDF, EPUB and Kindle. Book excerpt: "This work holds the proceedings of the Global Soil Map 2017 conference, held in Moscow, Russia between July 4-6, 2017. The last decade has shown an increasing demand for information on the state of the world's soils, from areas such as soil management, global food security, ecological sustainability, and scientists who model biospheric processes under the influence of climate change. The most recent version of the Soil Map of the World was made in 1985. Since then, new knowledge on soil geography and field data has been accumulated, allowing for the creation of many regional and local soil maps.Completely new technologies such as geospatial technologies and remote sensing have been developed. All this created the preconditions for the beginning of the work on a new digital Global Soil Map.To reach this ambitious aim a number of leading soil science institutions of various countries of the world created a Consortium that aimed to develop a methodology for global digital soil mapping, verify this methodology in different regions, and finally to make a digital Global Soil Map.Methodology and approaches are discussed at a series of annual business meetings, international scientific workshops and conferences, the most important previous ones have been held in Orleans (France) in 2013 and in Ottawa (Canada) in 2015."--Provided by publisher.

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.
