Tangram Heightmapper

This is an elevation data browser, which "auto-exposes" the display so that the highest and lowest visible elevations are white and black. The result is a grayscale heightmap, suitable for use as a displacement map in 3D applications.

Here's a blog post about this tool, with more explanations and examples!

Usage:

Terrain data is coming from Mapzen's global terrain tiles.
