Dr.
Isobel Clark Isobel Clark has taught, researched and consulted in the
field of geostatistics for almost 30 years. Possibly best known as the author
of the introductory text "Practical Geostatistics" (1979), she is
now co-author of a more complete textbook, Practical Geostatistics 2000 which
is available as hypertext on CD and as a hardcopy book. Software and data
sets are available to all.
Her recent consultancy assignments range from the

Geostatistics is the name given to a particular group of techniques
which model spatial processes and allow estimation of values at unsampled
locations. Geostatistical estimation is a two stage process: i. studying the gathered data to
establish the predictability of values from place to place in the study area;
ii. estimating values at those locations which
have not been sampled. This process is known as ‘kriging’. In mining, geostatistics is extensively used in the field
of reserve valuation - the estimation of grades and other parameters from a
relatively small set of borehole or other samples.
Geostatistics is now widely used in many other fields.
Obviously there are geological and geographical applications. However, the
techniques are also used in such diverse fields as hydrology, ground water
and air pollution, soil science and agriculture, forestry, epidemiology,
management of wildlife and weather prediction. |

to Kriging: As the name suggests, this course takes interested students
from no knowledge of statistics or geostatistics through to the mysteries of
ordinary kriging and its variants in 30 hours (or less). This is a classroom
course and includes manual exercises to reinforce understanding of the
techniques. WHO SHOULD ATTEND? This course is aimed at any professionals dealing with the
estimation from or interpolation between samples collected on a spatial
basis. This is not a course for specialist geostatisticians
but intended rather for those who wish to use geostatistics to enhance their
practical applications or research. All lectures will be augmented by desktop exercises
covering many different applications and candidates should come equipped with
a calculator capable of taking natural logarithms. Questions and discussions are actively encouraged and,
indeed, form the basis of a successful course. |
Day 1: The basic assumptions of spatial
estimation methods; Inverse Distance interpolation methods; Classical
statistics: the Normal distribution. Statistical methods: the lognormal
distribution; confidence levels; standard errors; grade/tonnage curves. Geostatistical methods: the
experimental semi-variogram; modelling semi-variograms; trends; anisotropy;
geological features. Geostatistical estimation: weighted
averages; estimation errors; standard errors; confidence levels; ordinary and
simple kriging; cross validation. Variations on kriging; lognormal
methods; indicator methods; non-linear geostatistics; regression problems
(conditional bias); simulation. 5 Continuing Education Units (CEUs) accredited by Independent Third Party Review Panel

WHO SHOULD ATTEND? This course allows participants to analyse their own data
using the Geostokos Toolkit
under supervision. The course is aimed at geologists, mining engineers,
surveyors, biologists, agriculturalists, statisticians, environmentalists and
any other professionals dealing with the estimation from or interpolation
between samples collected on a spatial basis. A basic level of knowledge of statistical and geostatistical methods is assumed. For example, previous
participants in 'Zero to Kriging in 30 hours' will find
this course eminently appealing. No mathematical expertise is necessary to
carry out the analysis. All techniques are illustrated by exercises covering
many different applications. Questions and discussions are actively encouraged and,
indeed, form the basis of a successful course. Participants should, if
possible, bring their own data for independent study. Basic computer skills and a familiarity with PC Windows
systems are an advantage but not essential. Participants may take away copies of all software and data
sets. |
Flexible! All sessions include a mixture of
formal lecture, general discussion and hands on computer analysis. The
timetable is flexible and is always adjusted to reflect the interests of the
class participants. Day 1, morning: Introduction to Geostokos Software,
Tutorial exercises on statistical and geostatistical analysis using the data
sets from Practical Geostatistics 2000. Day 1, afternoon: Consideration of statistical
distribution and its contribution to interpretation of sample data;
identification of multiple components and likely indicator discriminators;
lognormal and other distributions. Day 2, morning: Construction and interpretation of
semi-variograms; identification of trends; multi-component models;
confirmation of basic assumptions; outliers. Day 2, afternoon: Choice of appropriate kriging
techniques; practical applications of kriging; confidence and standard
errors. Day 3: Case studies from Geostokos Ltd and
from course participants; general discussion of case studies; simulation
techniques; multi-variable problems and co-kriging. |
