Hi everyone,
Lets say we have measured three soil particule size values for clay, silt
and sand, all adding to one.
cl + s i + sa = 1
What would be the best way to take into account each particule size, so
the interpolated values still add up to one?
Is there any geostatistical process that can h
Hi Marc,
You may want to look at the following paper:

The simplest solution - in the sense that most
packages could handle it - is to carry out a 'nested'
indicator analysis.
That is:
(i) code one of your particle classes as '1' and all
other as '0', produce a map of proportion of this
class.
(ii) remove this particle class from your

You can try our recent publication in the Journal "Soil
Science" which compared several geostatistical techniques for
simultaneously interpolating soil particle-size fractions while ensuring
summation to a constant. The reference is:
