DSM USA 30 Sept-3 Oct 2008

3rd Global Workshop on Digital Soil Mapping (DSM 2008 USA), “Digital Soil Mapping: Bridging Research, Production, and Environmental Application.” Visit http://dsmusa.org/

This workshop will cover the following topics:

  1. Evaluating and using legacy data in digital soil mapping.
  2. Exploring new sampling schemes and environmental covariates in digital soil mapping.
  3. Using integrated sensors or other new technologies for inferring soil properties or status.
  4. Innovative inference systems (new methodologies for predicting soil classes and properties, and estimating uncertainties).
  5. Using digital soil mapping products and their uncertainties for soil assessment and environmental applications.
  6. Protocol and capacity building for making digital soil mapping operational.

General Information:

The workshop will be held at Utah State University in Logan, a small city located in Cache Valley between the Wellsville Mountains and the Bear River Range of northern Utah. Late September-early October is a stunningly beautiful time of year, with normally sunny and warm days, cool nights, and autumn colors.

There is an optional field trip on Tuesday, September 30, limited to 42 participants.

The three workshop days are 1-3 October. The workshop will consist of sessions that address each of the above topics. Each session will consist of an invited keynote talk (30 minutes) followed by contributed talks (minimum 5 minutes, maximum 10 minutes - the length will depend on the number of contributions.) There will be at least one hour for discussion of each topic, which will be led by a discussant. Each session will be summarized by a rapporteur. The final session will be a discussion to develop a set of key recommendations and future priorities for digital soil mapping.

Progress in Geomathematics

Celebrating Frits Agterberg’s half-century of publication activity in geomathematics, this volume’s 28 timely papers, written by his friends and colleagues, treat a variety of subjects of current interest, many of them also studied by Frits, including: spatial analysis in mineral resource assessment, quantitative stratigraphy, nonlinear multifractal models, compositional data analysis, time series analysis, image analysis, and geostatistics. Professor Agterberg published his first paper as a graduate student in 1958 and has since produced (and continues to publish) a steady stream of research papers on a wide variety of subjects of interest to geomathematical practitioners. Most of the papers included here address methodology and feature practical case studies, so that the book likely has broad appeal to those interested in mathematical geosciences, both to academic researchers seeking a comprehensive overview and also to practitioners of geomathematical approaches in industry.

This book will be available later this year from IAMG

Digital Soil Mapping with Limited Data

This book is the result of the 2nd Global Digital Soil Mapping Workshop held in Rio 4-7 July 2006.  This book edited by Alfred Hartemink, Alex  McBratney and Lou, focuses on digital soil mapping methodologies and applications for areas where data are limited, and has the following sections (i) introductory papers, (ii) dealing with limited spatial data infrastructures, (iii) methodology development, and (iv) examples of digital soil mapping in various parts of the globe (including USA, Brazil, UK, France, Czech Republic, Honduras, Kenya, Australia). The final chapter summarises priorities for digital soil mapping.

The book is published by Springer and will be available later this year. In the meantime, you can view part of it at: http://www.amazon.com/Digital-Soil-Mapping-Limited-Data/dp/1402085915

Best Papers in Pedometrics

“Best paper in Pedometrics” is an award presented annually by the Pedometrics Commission of the International Union of Soil Sciences.

Up to 2006, the procedure is as follows:

  • A renowned Pedometrician is asked to make a selection of 5 (or 6) papers from a list of journals where Pedometrics-related papers are published,

Pedometrics 2009

IFCS Conference 13-18 March 2009

Dear Pedometricians,

I would like to invite you to contribute to a Special Interest Session
on Spatial Classification that I will chair at the 11th Biennial
Conference of the International Federation of Classification Societies
(IFCS), which will take place at the University of Technology of
Dresden, Germany, March 13-18, 2009, in combination with the 33rd
annual conference of the German Classification Society - Gesellschaft
für Klassifikation (GfKl). Abstract deadline is November 3, 2008.

The focus of this Special Interest Session will be on applications and
methodological challenges of the classification of spatial data,
especially in, but not limited to, the context of remote sensing and
the
geosciences. Such applications include land cover classification and
change detection, landslide susceptibility modeling, mineral potential
mapping, or habitat analysis. Dealing with spatial autocorrelation in
model fitting and error estimation is one of the challenges
encountered in spatial classification. Specific applications such as
hyperspectral remote sensing result in additional challenges such as
high-dimensional data. Both applied and theoretical scientists with
diverse backgrounds are invited to contribute to this session that is
intended to provide an interdisciplinary discussion forum.

Papers of the conference will be published in a post-conference
proceedings volume in the series ‘Studies in Classification, Data
Analysis and Knowledge Organization’ with Springer-Verlag after having
passed a refereeing process (deadlines are listed below). Long or
advanced versions of papers can be submitted to the journals ‘Advances
in Data Analysis and Classification (ADAC)’ and ‘Journal of
Classification’ that both will publish a Special Issue for IFCS 2009.

I look forward to meeting you at the IFCS,

Alexander Brenning
Department of Geography and Environmental Management
