Datasets used in Spatial Relationships Between Two Georeferenced Variables

Below you will find links to comma-separated files (CSV) and/or Rdata (RDA) versions of additional data used in the book; please inform us if you notice anything missing.

nanotubes data

The flame retardant property of clay polymer nanocomposites improve the physical and flammability properties of polymers. The distribution of this nanotube was examined by optical microscopy. This distribution is believed to depend mainly on the distance from the top surface to the location of the polymer matrix (polymethyl methacrylate). The collected dataset consists of four 512 x 512 images.

The images are arranged in a dataset with 262144 rows and 6 variables.
