What is Interpolation?
9/2/2015 Spatial Analysis with ArcGIS
• Predict values at unknown locations using values at measured locations• Many interpolation methods: Deterministic and Geostatistical
What is Kriging?
9/2/2015 Spatial Analysis with ArcGIS
• 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
9/2/2015 Spatial Analysis with ArcGIS
• Exploratory Spatial Data Analysis (ESDA)• Interpolate
- estimation of values at unsampled locations based on known values
• Goodness of fit
