Geostatistics is essential for environmental scientists. Weather
and climate vary from place to place, soil varies at every scale at
which it is examined, and even man-made attributes – such as
the distribution of pollution – vary. The techniques used in
geostatistics are ideally suited to the needs of environmental
scientists, who use them to make the best of sparse data for
prediction, and top plan future surveys when resources are limited.
Geostatistical technology has advanced much in the last few
years and many of these developments are being incorporated into
the practitioner’s repertoire. This second edition describes
these techniques for environmental scientists. Topics such as
stochastic simulation, sampling, data screening, spatial
covariances, the variogram and its modeling, and spatial prediction
by kriging are described in rich detail. At each stage the
underlying theory is fully explained, and the rationale behind the
choices given, allowing the reader to appreciate the assumptions
and constraints involved.
