Hi You will find drift also referred to as "trend", generally understood as a change in the 'expected' value from place to place within your study area. For example, an airborne pollutant with a single source will show higher values close to the source tending to 'thin out' as the distance to the source increases. In this case, the relationship does not just depend on the distance between samples but also on the actual location relative to the source. We have a free tutorial on "kriging with trend" which can be found by following links on http://www.kriging.com Isobel
