5/11/2003: Shenandoah topography

The Earth Sci pic of the day yields this nice one of Virginia's Shenandoah national park by Shuttle Radar Topography Mission data.

Now here's the odd part: no camera was used to create this image.

They recorded the various elevations in detail, via radar on the shuttle. Then they created this image from that data: one pass to create the shading (which areas are light and which dark) and one to create the color (different heights of the land get different colors).
