Oilslick was made with elevation data. In the the middle of the text in the left-hand panel, the author wrote:
> The cycling and purity of colors looks a lot like a thin-film interference pattern, hence the name: oilslick. This could be a point of confusion for my more GIS-educated viewers: the pattern is easily mistaken for the raw result of radar interferometry elevation mapping [0] (which was the method used to produce most of the data in this dataset). But this is not the case; what you see here is final, post-processed elevation data.
