Objectives
What trainees will gain
- Calculate and interpret the variogram to characterise the spatial behaviour of the phenomenon studied.
- Interpolate a variable using a chosen method: by optimising the calculation parameters, by a geostatistical method, or by other means.
- Assess uncertainty.
Content
What the programme covers
Introduction
- The challenges and difficulties of interpolation when building a map, and the added value of geostatistical methods.
Characterising spatial data
- Quantifying spatial behaviour with the variogram: calculation and interpretation (continuity, anisotropy, non-stationarity and measurement errors), and modelling it.
Principles of geostatistical interpolation
- Kriging, its main variants and practical application: ordinary, non-stationary, and co-kriging with external drift.
- Cross-validation.
Non-geostatistical interpolation methods
- An overview of the main methods, their uses and limitations depending on data quality and the purpose of the maps, compared with geostatistical methods.
Practical computer applications
- Calculating and fitting the variogram, kriging variants, selecting interpolation and neighbourhood parameters, and analysing and validating results on real geoscience data.
Who for
Target audience
Geologists, engineers and geoscientists whose projects involve producing maps.
Method
How it is delivered
Computer-based work for most of the time, using real data.
A programme tailored to your organisation
The duration and topics of the programme are adjusted to the organisation's needs, and it is delivered at its site, in a training hall arranged by the Center, or virtually.
