This book describes statistical methods suitable for analyzing variation in soil and for relating soil to its environment. The authors stress sound sampling technique and show how to use the results for estimation, prediction, and efficient design. They show how classification can enhance the utility of survey data and lead to economies in sampling. Optimal methods for creating classification are described, and alternative multivariate methods are set forth for identifying relations such as principal component and co-ordinate analysis. The book expands and revises the author's Quantitative and Numerical Methods in Soil Classification and Survey. It includes information on regression, as used in both statistics and natural science. Three new chapters devoted to geostatistics introduce regionalized variable theory, and cover such applications as the variogram, its modelling, kriging, and isorithmic mapping. As with the first edition, the book stresses the full quantitative survey of land resources, measurement, and estimation. Many simple illustrations and tables are included to clarify the text.

This book describes suitable statistical methods for analyzing variation in soil and for relating the soil to its environment. Sound land planning increasingly needs such quantitative information and decisions have been made against a background of variation in soil and other land resources. The authors stress sound sampling technique and show how to use the results for estimation, prediction, and efficient design. They show how classification can enhance the utility of survey data and lead to economies in sampling. Optimal methods for creating classification are described as well as alternative multivariate methods for identifying relations such as principal component and principal co-ordinate analysis. This is essentially a second edition of Dr Webster's book "Quantitative and Numerical Methods in Soil Classification and Survey". In this edition the topic of regression is tackled from the viewpoints of both statistics and natural science. There are three new chapters devoted to geostatistics which introduce regional modelling, kriging, and isarithmic mapping. However, as in the first edition, the accent throughout is on fully quantitative survey of land resources, of measurement, and of estimation. The more advanced techniques are liberally illustrated with simple diagrams.

Guidelines for Surveying Soil and Land Resources promotes the development and implementation of consistent methods and standards for conducting soil and land resource surveys in Australia. These surveys are primarily field operations that aim to identify, describe, map and evaluate the various kinds of soil or land resources in specific areas. The advent of geographic information systems, global positioning systems, airborne gamma radiometric remote sensing, digital terrain analysis, simulation modeling, efficient statistical analysis and internet-based delivery of information has dramatically changed the scene in the past two decades. As successor to the Australian Soil and Land Survey Handbook: Guidelines for Conducting Surveys, this authoritative guide incorporates these new methods and techniques for supporting natural resource management. Soil and land resource surveyors, engineering and environmental consultants, commissioners of surveys and funding agencies will benefit from the practical information provided on how best to use the new technologies that have been developed, as will professionals in the spatial sciences such as geomorphology, ecology and hydrology.

The success of "At the Fireside" is a clear indication that readers are hungry for more of the same. "At the Fireside Volume 2" is a fresh offering of similar stories 'from the mouth' of Roger Webster. The stories are written in his typically colourful language. They are tales of bravery and honour, greed and failure, hope and despair, but ultimately the stories of real people who went beyond the expected, and of events that surpassed the ordinary.
