Thanks for all the help!

Without wanting to be deliberately picky, I&#x27;m not sure I see anything here that could not be done with a few clicks&#x2F;commands in a dedicated remote sensing&#x2F;raster analysis package, with GDAL and GRASS being a couple of obvious free options that spring to mind.<p>The maps in the Vatican museum are indeed very cool, in fact the Vatican in general blew me away, and I&#x27;ve seen a fair number of impressive historical sites in Europe&#x2F;Near East.

Why not throw it into Blender and get an actual pathtraced result. Here&#x27;s a quick render I made:<p><a href="https:&#x2F;&#x2F;i.imgur.com&#x2F;GBTjJUm.jpg" rel="nofollow">https:&#x2F;&#x2F;i.imgur.com&#x2F;GBTjJUm.jpg</a><p>Notice the correct soft self reflections on the sides of the hills in the shade.
