Duccio There are many reasons why your interpolations may not be working. A few of these are:
# you are beyond the range of influence of any distance relationship, that is you have too widely spaced sampling. # your data may have a skewed or other non-Gaussian distribution which makes both semi-variogram and correlation calculations invalid # you may have discontinuities, trends or anisotropies which have not been factored into your model Isobel http://drisobelclark.ontheweb.com ________________________________________________________________________ Want to chat instantly with your online friends?
