A spatial field is partially observed at selected sites and the goal is to infer the field at unobserved sites. This is the problem of spatial estimation, sometimes called spatial prediction. Examples of spatial fields are soil nutrient concentrations over an agricultural domain observed on a survey grid, hydrologic variables over an aquifer observed at well locations, and air quality measurements over an air basin observed at monitoring sites. Kriging is a method for converting the data into an estimate of the field together with a measure of error or uncertainty.
