Release Date: 2025-07-01
This book contributes to the advancement of scientific knowledge by demonstrating how geospatial technologies can support more effective coastal planning and management. These technologies, such as remote sensing, GIS, and GNSS, play a vital role in monitoring coastal ecosystems and offer powerful tools for data collection, analysis, visualization, and decision-making. They enhance the understanding of coastal needs and enable more informed and sustainable management strategies. Intended for scientists, professionals, researchers, planners, students, and the general public, the book promotes a deeper understanding of how geospatial tools address contemporary coastal challenges. It also emphasizes inclusive decision-making and supports the development of strategies for sustainable socio-ecological coastal systems. The book is structured into six parts. Part One introduces the fundamentals of remote sensing, including sensor networks, satellite systems, aerial imaging, photogrammetry, and air photo interpretation. Part Two covers key GIS concepts, data analysis, database management, digital image processing, and participatory GIS. Part Three explores GNSS and GPS techniques. Part Four discusses the application of geospatial tools in coastal ecological monitoring and management. Part Five presents real-world case studies and field narratives that explore a range of topics, including climatic trend analysis, shoreline dynamics modelling, mangrove canopy health, coastal land use and land cover changes, land surface temperature variations, ecological transformations, mangrove-human conflicts, climate adaptation strategies, the management of climate gaps, spatial considerations in coastal zone management, and the role of climate communication in shaping coastal narratives. And finally, Part Six examines the evolving nature of coastal research, highlighting the role of GIScience in transdisciplinary approaches and strategic decision-making.
Coastal Navigation
Coastal Navigation for Class and Home Study is based on the notes prepared for students by the author during some 20 years of teaching navigation, initially to private or commercial pilots, and then to sailors and professional mariners. The book is copiously illustrated with graphics which explain chart projections, scales and symbols, and describe lights and other navigation aids. It demystifies the True, Magnetic and Compass Norths as well as problems of time, speed and distances, and explains how to plot courses and take bearings, or draw regular and advanced Lines of Position using the international system of labeling. The book further clarifies the use of vectors to easily determine the impact of a current on the boat speed and direction, and goes on to show how to evaluate tides and currents. The final sections describe the use of GPS and electronic charts, highlighting their limitations. Additional notes and explanations are given in the areas where students traditionally experience difficulties, as well as supplementary examples and exercises. The companion book, Coastal Navigation Exercises, offers all the exercises needed for practice.
