Figure 4. Flowchart of the algorithmic pipeline used for remote fossil site detection.

(1) Example of one of the seven spectral bands satellite images used in this study; (2) false colour map based on the infrared bands, after cropping to study area; (3) results of clustering using all seven spectral bands; (4) Binarize clusters for classification by selecting the cluster that contains most fossil sites as the target class (“walking back the cat”) versus all other clusters combined into a single class.
