		<description><![CDATA[I&#8217;ve covered the program 3DEM before on this blog; it&#8217;s a first-rate 3D terrain visualization program, and does the best out-of-the-box map relief shading of any free program I know. Here&#8217;s a standard USGS topo shaded with a digital elevation model using this program:

Unfortunately, the author, Richard Horne, has ceased development of the program, and [...]

		<description><![CDATA[For general map relief shading, my first choice is usually 3DEM, since it usually gives the best results. But MicroDEM also does a decent job at terrain relief shading, and has a few other shading options that 3DEM lacks.

Here&#8217;s my favorite sample DEM again, loaded into MicroDEM in reflectance mode:

And here&#8217;s a section of a [...]

Now it&#8217;s time to look at different ways to display terrain reflectance in DEM. While 3DEM is better for some kinds of displays, MicroDEM has more different ways to display reflectance.

Here&#8217;s the last reflectance plot from yesterday:
