Environmental Soil-Landscape Modeling: Geographic Information Technologies and Pedometrics presents the latest methodological developments in soil-landscape modeling. It analyzes many recently developed measurement tools, and explains computer-related and pedometric techniques that are invaluable in the modeling process. This volume provides an in-depth overview of the history of soil-landscape modeling. By uniting the work of soil scientists from diverse backgrounds, it promotes quantitative soil-landscape modeling as a joint venture among those involved with soil geography, soil genesis, and pedometrics. About the Editor Sabine Grunwald is an Assistant Professor in the Soil and Water Science Department, Institute of Food and Agricultural Sciences, at the University of Florida, Gainesville. She is the current vice-chair of the Commission 1.5 Pedometrics of the International Union of Soil Sciences.

Digital Soil Mapping is the creation and the population of a geographically referenced soil database. It is generated at a given resolution by using field and laboratory observation methods coupled with environmental data through quantitative relationships. Digital soil mapping is advancing on different fronts at different rates all across the world. This book presents the state-of-the art and explores strategies for bridging research, production, and environmental application of digital soil mapping.It includes examples from North America, South America, Europe, Asia, and Australia. The chapters address the following topics: - evaluating and using legacy soil data - exploring new environmental covariates and sampling schemes - using integrated sensors to infer soil properties or status - innovative inference systems predicting soil classes, properties, and estimating their uncertainties - using digital soil mapping and techniques for soil assessment and environmental application - protocol and capacity building for making digital soil mapping operational around the globe.

Das satellitengestützte Positionierungssystem GPS wurde ursprünglich für die militärische Navigation konzipiert und entwickelt. Bald wurden aber auch die Anwendungsmöglichkeiten im zivilen Bereich erkannt. Unter anderem zählt GPS heute bereits zu den Standardmethoden der geodätischen Punktbestimmung, wobei Genauigkeiten bis in den Millimeterbereich erzielt werden können. Dieses Buch richtet sich an alle, die eine praxisbezogene Beschreibung von GPS hinsichtlich der Beobachtung und der Auswertung suchen. Nach einer elementaren Einführung in das Prinzip von GPS werden die wichtigsten Aspekte der Beobachtung beginnend von der Planung über die Durchführung bis zur Berechnung der Basisvektoren beschrieben. Das Schwergewicht des Buches liegt in der Auswertung. Im Detail werden die Netzbildung, die Transformation der GPS-Ergebnisse in das lokale geodätische Datum sowie die gemeinsame Ausgleichung von GPS und terrestrischen Messungen behandelt, wobei zahlreiche numerische Beispiele angeführt sind. Im Anhang sind neben den Zahlenwerten für die Parameter der bekanntesten Ellipsoide auch die Formelsysteme für die gebräuchlichsten konformen Abbildungen enthalten.
