Ground-truthing Fractals

Detailed view of four 500-m x 500-m tiles. The tiles are depicted both in plan and perspective views to convey a visual sense of roughness corresponding to their respective fractal dimensions. Tile A lies in the shallow patch-reef zone, Tile B covers a portion of a fused reef, Tile C falls within the deep patch-reef zone, and Tile D is situated on the crest of Pacific Reef. Note that Tile B has been rotated 180° from its true orientation to provide a better topographic view. The white streak in the lower left portion of this tile is a boat wake.
