Webgl Shaded Relief

--- layout: example.html title: Shaded Relief (with WebGL) shortdesc: Calculate shaded relief from elevation data docs: >

For the shaded relief, a single tiled source of elevation data is used as input. The shaded relief is calculated by the layer's style with a color expression. The style variables are updated when the user drags one of the sliders. The band operator is used to sample data from neighboring pixels for calculating slope and aspect, which is done with the ['band', bandIndex, xOffset, yOffset] syntax.
