Environmental Geoinformatics

Assembling a wealth of multi-disciplinary techniques for addressing environmental problems such as pollution and climate change, this volume features simplified presentation aimed at non-experts, demonstrating geoinformatics potency as a research toolkit.

This second edition includes updated chapters from the first edition as well as five additional new chapters (Light detection and ranging (LiDAR), CORONA historical de-classified products, Unmanned Aircraft Vehicles (UAVs), GNSS-reflectometry and GNSS applications to climate variability), shifting the main focus from monitoring and management to extreme hydro-climatic and food security challenges and exploiting big data. Since the publication of first edition, much has changed in terms of technology, and the demand for geospatial data has increased with the advent of the big data era. For instance, the use of laser scanning has advanced so much that it is unavoidable in most environmental monitoring tasks, whereas unmanned aircraft vehicles (UAVs)/drones are emerging as efficient tools that address food security issues as well as many other contemporary challenges. Furthermore, global navigation satellite systems (GNSS) are now responding to challenges posed by climate change by unravelling the impacts of teleconnection (e.g., ENSO) as well as advancing the use of reflected signals (GNSS-reflectometry) to monitor, e.g., soil moisture variations. Indeed all these rely on the explosive use of big data in many fields of human endeavour.
Moreover, with the ever-increasing global population, intense pressure is being exerted on the Earth's resources, leading to significant changes in its land cover (e.g., deforestation), diminishing biodiversity and natural habitats, dwindling fresh water supplies, and changing weather and climatic patterns (e.g., global warming, changing sea level). Environmental monitoring techniques that provide information on these are under scrutiny from an increasingly environmentally conscious society that demands the efficient delivery of such information at a minimal cost. Environmental changes vary both spatially and temporally, thereby putting pressure on traditional methods of data acquisition, some of which are highly labour intensive, such as animal tracking for conservation purposes. With these challenges, conventional monitoring techniques, particularly those that record spatial changes call for more sophisticated approaches that deliver the necessary information at an affordable cost. One direction being pursued in the development of such techniques involves environmental geoinformatics, which can act as a stand-alone method or complement traditional methods.

Brings together multi-disciplinary techniques to support the acquisition, analysis, and visualisation of geodata Includes numerous colour photos, as well as relevant and practical examples Features special chapters on applications and updated technologies involving big data and new challenges

Professor Joseph Awange joined Spatial Sciences (School of Earth and Planetary Sciences, Curtin University, Australia) in 2006 under a Curtin Research Fellowship and concurrently undertook the prestigious Alexander von Humboldt (AvH) Fellowship at the Geodetic Institute (Karlsruhe Institute of Technology, Germany) having been awarded the Australian 2008-2011 Ludwig Leichhardt Memorial Fellowship for experienced researchers. In 2015, he won all the three major Fellowship Awards: Alexander von Humboldt (Germany), Japan Society of Promotion of Science (Japan) and Brazil Frontier of Science (Brazil) to carry out research in those countries. At Curtin University, he is currently a Professor of Environmental Geoinformatics engaged in teaching and research having attracted more than $2.5M worth of research grants. He obtained his BSc and MSc degrees in Surveying from the University of Nairobi (Kenya), and was also awarded a merit scholarship by the German Academic Exchange Program (DAAD), which facilitated his obtaining a second MSc degree and PhD in Geodesy at Stuttgart University (Germany). In 2002-2004, he was awarded the prestigious Japan Society for Promotion of Science (JSPS) Fellowship to pursue postdoctoral research at Kyoto University (Japan). Prof Awange attained International Editorial role in Springer Earth Science Books and has authored 15 scholarly books with the prestigious Springer International publishers and more than 160 peer-reviewed high impact journal publications (in e.g., Remote Sensing of Environment, Journal of Climate, Climatic Change, Advances in Water Resources, International Journal of Climatology, and Journal of Hydrology among others). His main research areas that have attracted media coverage (e.g., Environmental Monitor) are in the fields of (i) Environmental Geoinformatics: Satellite Environmental Sensing (e.g., changes in global and regional stored water (surface, underground, ice, and soil moisture) using GRACE and TRMM satellites; Climate Change using GNSS and altimetry satellites), which is employed to face the emerging challenges of the 21st century posed by increased extreme hydroclimatic conditions, e.g., severity and frequency of droughts in Australia and Greater Horn of Africa (GHA), and the changing monsoon characteristics in Asia and Africa leading to floods, and (ii) Mathematical Geosciences: Hybrid-symbolic solutions that delivers hybrid symbolic-numeric computations (HSNC), which is a large and growing area at the boundary of mathematics and computer science and currently an active area of research.
Professor John Kiema is currently the Director of Technical Services, Regional Centre for Mapping of Resources for Development (RCMRD) having first served as Director of Remote Sensing, GIS and Mapping at RCMRD. He is also Associate Professor, Department of Geospatial and Space Technology, University of Nairobi (Kenya). He obtained his BSc, MSc degrees in Surveying and Postgraduate Diploma (Computer Science) from the University of Nairobi (Kenya). He was awarded a merit scholarship by the German Academic Exchange Program (DAAD), which facilitated his obtaining PhD in Remote Sensing and GIS at Karlsruhe (Germany). He has published widely and supervised postgraduate degrees. He is the immediate past Executive Secretary of the Eastern Africa Land Administration Network (EALAN) and during his sabbatical leave in Rwanda he helped mentor and the first ever Land Survey graduates in the history of Rwanda. In his current post Prof. Kiema is in-charge of all technical activities at RCMRD including the SERVIR Project that is a Partnership between NASA, USAID, and RCMRD and Global Monitoring for Environment and Security (GMES) & Africa an initiative of the European Union (EU) and African Union (AU). Prof. Kiema also serves in the Steering Committee of Group of Earth Observation (GEO) on Disaster Risk Management (GEO-DARMA) and Social Tenure Domain Model (STDM) Advisory Committee. He is also Executive Board Chairman, Working Group on Land Cover for Africa (WGLCA) and member of Kenya National Academy of Sciences (MKNAS).
