AI-GEOSTATS: kriging estimation precision

2008-01-14 Thread G. Allegri
Hi everyone, this is my very first post on this mailing-list. I need to produce a map of soil salinity space variability. I have chosen to compare the estimation of OK, Regression Kriging and Indicator Kriging reliability on my data-set. I know that kriging variance depends only on the geometrical

Hi Well, in general the simulations are useful if you need to evaluate spatial uncertainty, for example if you have to apply some transfer function to your data or the need to evaluate the probability that some neighbor cells overcome jointly a given threshold. Then kriging variance is

Thank you very much for the replies. I've found the papers suggested by Mahmut very useful, as I'm asked to find a method to spatialize soil salinity measures (Ece and SAR) to investigate/forecast the salinity risk in coastal areas under saline waters irrigation (temporal changes will be
