Book excerpt: Com os recentes avanços tecnológicos na agropecuária, os especialista nos diversos campos correlatos tem notado, cada vez mais, importância de se medir a variação espacial e temporal para que se possa ter uma melhor aplicação e aproveitamento dos recursos sgricultáveis, podendo reduzir o número de variáveis de entrada e diminuir, dessa maneira, os cistos. O gerenciamento em função da variabilidade, é o que convencionou-se chamar Agricultura de precisão. Seu objetivo e correlacionar causas e efeitos a partir de series históricas de dados e suas destribuição espacial, analisando sua variabilidade.

Available in PDF, EPUB and Kindle. Book excerpt: This book reports on developments in Proximal Soil Sensing (PSS) and high resolution digital soil mapping. PSS has become a multidisciplinary area of study that aims to develop field-based techniques for collecting information on the soil from close by, or within, the soil. Amongst others, PSS involves the use of optical, geophysical, electrochemical, mathematical and statistical methods. This volume, suitable for undergraduate course material and postgraduate research, brings together ideas and examples from those developing and using proximal sensors and high resolution digital soil maps for applications such as precision agriculture, soil contamination, archaeology, peri-urban design and high land-value applications, where there is a particular need for high spatial resolution information. The book in particular covers soil sensor sampling, proximal soil sensor development and use, sensor calibrations, prediction methods for large data sets, applications of proximal soil sensing, and high-resolution digital soil mapping. Key themes: soil sensor sampling – soil sensor calibrations – spatial prediction methods – reflectance spectroscopy – electromagnetic induction and electrical resistivity – radar and gamma radiometrics – multi-sensor platforms – high resolution digital soil mapping - applications Raphael A. Viscarra Rossel is a scientist at the Commonwealth Scientific and Industrial Research Organisation (CSIRO) of Australia. Alex McBratney is Pro-Dean and Professor of Soil Science in the Faculty of Agriculture Food & Natural Resources at the University of Sydney in Australia. Budiman Minasny is a Senior Research Fellow in the Faculty of Agriculture Food & Natural Resources at the University of Sydney in Australia.

Available in PDF, EPUB and Kindle. Book excerpt: 1.1 Overview V ARIOWIN 2.2 is a collection of four WindowsTM programs - Prevar2D, Vari02D with PCF, Model, and Grid Display - that are used for spatial data analysis and variogram modeling of irregularly spaced data in two dimensions. Prevar2D builds a pair comparison file (PCF), that is, a binary file containing pairs of data sorted in terms of increasing distance. Pair comparison files can be built from subsets in order to reduce memory requirements. Vari02D with PCF is used for spatial data analysis of 2D data. It uses an ASCII data file and a binary pair comparison file produced by Prevar2D. Features implemented in Vari02D with PCF include: • the possibility to characterize the spatial continuity of one variable or the joined spatial continuity of two variables, • variogram surfaces for identifying directions of anisotropies, • directional variograms calculated along any direction, • several measures of spatial continuity. Not only the variogram but also the standardized variogram, the covariance, the correlogram, and the madogram are used to measure spatial continuity. • h-scatterplots to assess the meaning of these measures, • the identification and localization of pairs of data adversely affecting the measure of spatial continuity. Once identified, these pairs can be masked from the calculation interactively. • variogram clouds for identifying pairs of data values having the most influence on the measure of spatial continuity. Those pairs can also be located on the sample map.

Available in PDF, EPUB and Kindle. Book excerpt: The University of Minho (UMinho) defined some years ago a comprehensive and integrative research policy in order to actively contribute to pushing the frontiers of human knowledge, to the reinforcement of the national scientific system, and to the consolidation of its institutional position both in national and international arenas. Thus, the commitment to become a research university is stated in the different strategic documents approved by the University along the last decade. UMinho defined a clear strategy in order to be an open and permanent space for the creation of knowledge and the furtherance of nationally and internationally relevant innovation across the different areas of knowledge. Being a comprehensive University, UMinho aims at fostering high quality research in all the scientific domains in which our Research Units inscribe their activity: Sciences, Health and Life Sciences, Engineering and Technology, Social Sciences and Arts and Humanities. From the very beginning, UMinho has adopted the principles of open access and open science. We aim at carrying out our scientific activity in a transparent and collaborative way, actively promoting the sharing and communication of research processes, data and outputs. We are convinced that we do better science when we make it both more sensitive to the needs of society and also more effective in what concerns the allocated resources. As we see it, accountability is a pre-requisite for reinforcing citizen awareness of the contributions of science to a better world. These are the reasons why UMinho played a pioneering role in allowing open access to its publications and why it is currently expanding its sharing of research data. At UMinho, research is carried out in close connection with education. The University is increasingly involving students of the different learning cycles in research activities. Conversely, both PhD students and post-doctoral researchers play a role in teaching activities. Acting in this way, not only do we guarantee better quality education but we also establish the basis for a sustainable development of the scientific system and the fostering of scientific culture. We conceive research as a global enterprise, seeking for the answers to the main challenges of our times. In this sense, research is essentially international and requires the continuous reinforcement of international collaborations and participation in international initiatives, namely in the context of the European Research Area. At the same time, we are always promoting the multiplier effects of the scientific research we undertake for the socio-economic and cultural development of the country and of our region. The University’s high-quality scientific performance is clear when we consider: (i) the results of the international evaluation of our Research Units carried out by the National Science Foundation (FCT); (ii) the position that UMinho has been achieving in important international rankings; (iii) the number and diversity of University projects approved under the 7th Framework Program and the H2020; and (iv) the large collaboration projects with companies and other organisations that are under development. The high standards of the activity of our Research Units is made clear in this publication. When we consider the characteristics of their human resources, their publications, the projects funded by national and international agencies, the national and international recognition of their researchers, the networks with which they are engaged, and the scientific events they promote it becomes clear how well positioned in the national and international context our Research Units are. This publication gives a general overview of research in UMinho along the year of 2018. It is the first of a series providing detailed information about the research work of the University. Research at UMinho is governed by a permanent concern with providing feedback to the scientific community and to our fellow citizens as most of our funding is from public sources. Together with the adoption of external evaluation procedures, providing feedback is one of the best ways to establish the relevance of science undertaken for the public good, and for guaranteeing the scientific independence of our researchers and their Research Units. Nowadays, science is essential for fostering social and economic development. Through this publication we reveal the relevant role that UMinho is playing in this enterprise.
