Spatial Smoothing and Spatial Interpolation
Pages 22

This chapter covers two more generic tasks in GIS-based spatial analysis: spatial smoothing and spatial interpolation. Spatial smoothing and spatial interpolation are closely related and are both useful to visualize spatial patterns and highlight spatial trends. Some methods (e.g., kernel estimation) can be used in either spatial smoothing or interpolation. There are varieties of spatial smoothing and spatial interpolation methods. This chapter only covers those most commonly used.
