What is Interpolation?


• Predict values at unknown locations using values at measured locations• Many interpolation methods: Deterministic and Geostatistical

What is Kriging?


• Kriging is a geostatistical interpolation technique• The optimal interpolation method if the data meets certain conditions.• Associates uncertainty with the predictions• What are these conditions?

- Normally distributed- Stationary- No trends

• How do I check these conditions?- Exploratory Spatial Data Analysis (ESDA)

Interpolation workflow


• Exploratory Spatial Data Analysis (ESDA)• Interpolate

- estimation of values at unsampled locations based on known values

• Goodness of fit
