ASTM D 5923 Document Information:
Title
Standard Guide for Selection of Kriging Methods in Geostatistical Site Investigations
ASTM International
Publication Date:
Apr 10, 1996
Scope:
This guide covers recommendations for selecting appropriate kriging
methods based on study
objectives, exploratory data analysis, and analysis of spatial
variation.
This guide considers commonly used forms of kriging, including
ordinary kriging, simple kriging,
lognormal kriging, universal kriging, and indicator kriging.
Multivariate, spacetime, and other
less-frequently used kriging methods are not discussed; however, this
is not intended to reflect
any judgement as to the validity of these methods.
This guide describes conditions for which kriging methods are not
appropriate and for which
geostatistical simulations approaches should be used.
This guide does not discuss non-geostatistical alternatives to
kriging, such as splines or
inverse-distance techniques.
This guide does not discuss the basic principles of kriging.
Introductions to geostatistics and
kriging may be found in numerous texts including Refs (1-3).(Footnote
2) A review of kriging
methods is given in Ref. (4).
This standard does not purport to address all of the safety concerns,
if any, associated with its
use. It is the responsibility of the user of this standard to
establish appropriate safety and
health practices and determine the applicability of regulatory
limitations prior to use.
This guide offers an organized collection of information or a series
of options and does not
recommend a specific course of action. This document cannot replace
education or experience and
should be used in conjunction with professional judgment. Not all
aspects of this guide may be
applicable in all circumstances. This ASTM standard is not intended to
represent or replace the
standard of care by which the adequacy of a given professional service
must be judged, nor should
this document be applied without consideration of a project's many
unique aspects. The word
"Standard" in the title of this document means only that the document
has been approved through the
ASTM consensus process.
Footnote 2 - The boldface numbers in parentheses refer to a list of
references at the end the text.
