Research and technological advances have made
it possible for geologists to get a better view -- and understanding
-- of outcrops. The example below shows a clastic outcrop from the
deep-water slope channels of the Tebernas Basin in southern Spain;
it is a blended image that applies laser intensity texture to an
optimized surface model. The optimization process selects data points
that best define the outcrop shape while limiting excess points.
