EXPERT ELICITATION FOR THE VARIOGRAM

INTRODUCTION


Mapping and predicting environmental properties such as soil nutrients, vegetation characteristics, weather and climate variables from point observations require modelling of the spatial variability of these properties. In geostatistics, the spatial variability of environmental properties is characterized by the variogram.
In this web-based elicitation procedure you, the expert, will jointly with other experts define the variogram of a specific environmental variable for a specific area. The elicitation is set up such that no prerequisite knowledge about geostatistics is required. It is only your expert knowledge about the spatial variation of the variable that is needed.

TASKS TO DO


The experts are asked to complete several tasks during the elicitation procedure:

  1. Read the case study description
  2. Read the briefing document
  3. Elicit the marginal distribution of the environmental variable
  4. Elicit the variogram of the environmental variable
