"I learned, I laughed, I sighed, I swooned. What an absolutely delightful romp through the forest."—Kate Harris, author of Lands of Lost Borders "Intimate, open-hearted. . . A personal introduction to one of the most profoundly alive places on earth."—John Vaillant, author of The Golden Spruce A funny, deeply relatable book about one woman's quest to track some of the world's biggest trees. Amanda Lewis was an overachieving, burned-out book editor most familiar with trees as dead blocks of paper. A dedicated "indoorswoman," she could barely tell a birch from a beech. But that didn't stop her from pledging to visit all of the biggest trees in British Columbia, a Canadian province known for its rugged terrain and gigantic trees. The "Champion" trees on Lewis's ambitious list ranged from mighty Western red cedars to towering arbutus. They lived on remote islands and at the center of dense forests. The only problem? Well, there were many. . . Climate change and a pandemic aside, Lewis's lack of wilderness experience, the upsetting reality of old-growth logging, the ever-changing nature of trees, and the pressures of her one-year timeframe complicated her quest. Burned out again—and realizing that her "checklist" approach to life might be the problem—she reframed her search for trees to something humbler and more meaningful: getting to know forests in an interconnected way. Weaving in insights from writers and artists, Lewis uncovers what we’re really after when we pursue the big things—revealing that sometimes it's the smaller joys, the mindsets we have, and the companions we're with that make us feel more connected to the natural world.
Nominated for the 2019 Red Maple Fiction Award When Tristan’s dad disappears, he puts his tracking skills to the test to find him — but will Tristan’s talents save him if it turns out to be a trap? Thanks to his dad’s coaching, sixteen-year-old Tristan is one of the best climbers and trackers in his small town. He can read footprints and bushes like they’re security-camera footage, and fearlessly descend rock faces and waterfalls. But when his father disappears, leaving his mother too grief-stricken to function, the young canyoneer’s life goes into freefall. Left in the hands of a well-meaning but incompetent uncle and a space-cadet housekeeper, Tristan finds life a struggle no matter how hard he works. When he nears the end of his rope at home, the teen decides to set off into Swallow Canyon in search of his father — only to realize that someone may be out to get him. Now the question is who’s stalking whom, and are Tristan’s skills up to the dangerous game playing out in the deep, shadowy canyon?
Space geodetic techniques, e.g., global navigation satellite systems (GNSS), Very Long Baseline Interferometry (VLBI), satellite gravimetry and altimetry, and GNSS Reflectometry
In the summer of 2000 the German geo-research satellite CHAMP was launched into orbit. Its innovative payload arrangement and the low initial orbit allow CHAMP to simultaneously collect and almost continuously analyse precise data relating to gravity and magnetic fields at low altitude. In addition, CHAMP also measures the neutral atmosphere and ionosphere using GPS techniques. Three years after launch, more than 200 CHAMP investigators and co-investigators from all over the world met at the GeoForschungsZentrum in Potsdam to present and discuss the results derived from the extensive data sets of the mission. The main outcome of this expert meeting is summarized in this volume. The book offers a comprehensive insight into the present status of the exploitation of CHAMP data for Earth system research and practical applications in geodesy, geophysics and meteorology.
Our planet is currently experiencing substantial changes due to natural phen- ena and direct or indirect human interactions. Observations from space are the only means to monitor and quantify these changes on a global and long-term p- spective. Continuous time series of a large set of Earth system parameters are needed in order to better understand the processes causing these changes, as well as their interactions. This knowledge is needed to build comprehensive Earth s- tem models used for analysis and prediction of the changing Earth. Geodesy and geophysics contribute to the understanding of system Earth through the observation of global parameter sets in space and time, such as tectonic motion, Earth surface deformation, sea level changes and gravity, magnetic and atmospheric elds. In the framework of the German geoscience research and development p- gramme GEOTECHNOLOGIEN, research projects related to the theme “Observing the Earth System from Space” have been funded within two consecutive phases since 2002, both covering 3 years. The projects address data analysis and model development using the satellite missions CHAMP, GRACE, GOCE and comp- mentary ground or airborne observations. The results of the rst phase projects have been published in the Springer book, titled “Observation of the Earth System from Space”, edited by Flury, Rummel, Reigber, Rothacher, Boedecker and Schreiber in 2006. The present book, titled “System Earth via Geodetic-Geophysical Space Techniques” summarizes in 40 scienti c papers the results of eight coordinated research projects funded in the second phase of this programme (2005–2008).
Geodetic datum (including coordinate datum, height datum, depth datum, gravimetry datum) and geodetic systems (including geodetic coordinate system, plane coordinate system, height system, gravimetry system) are the common foundations for every aspect of geomatics. This course book focuses on geodetic datum and geodetic systems, and describes the basic theories, techniques, methods of geodesy. The main themes include: the various techniques of geodetic data acquisition, geodetic datum and geodetic control networks, geoid and height systems, reference ellipsoid and geodetic coordinate systems, Gaussian projection and Gaussian plan coordinates and the establishment of geodetic coordinate systems. The framework of this book is based on several decades of lecture noted and the contents are developed systematically for a complete introduction to the geodetic foundations of geomatics.
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.
