Lake Whistleman - pure SVG filter topo

Lake Whistleman - pure SVG filter generative map with multilevel contour lines and hill shading. No JavaScript or topo data. Around 800 bytes on the network after removing comments, spaces and compressing, most of it is the palette. The PNG screenshot is 1.4MB. Looks good on hi-res screens e.g. Retina.

Slow to render because SVG is scalable in resolution but not in performance - at least its browser implementations are disappointingly slow.

It uses a slightly modified version of the excellent Esri Europe2 color run (see LICENSE.txt) but any other palette would work.

It's a variation on the interactive 3D bumpmapped variant with light.

Built with blockbuilder.org
