I wanted to get a feel for the landscape in which Philae is set to land. I had already built a resonably accurate terrainmodel of the area. So I decided to play a little with the data.

The result are these two maps.

First a map showing the slope of the terrain. There are a few really steep places in the landing area but most of it is thankfully rather flat.

Then a slightly more worrying map showing the surface roughness. There are a few boulder fields that scare. but much of the area seem to be smooth (at least on the scales resolved in my dataset.)

Obviously my methods are not as refined as the ones employed by the mission teams but these maps should give an idea of the challenges facing the little lander.

 

I also made this Anaglyph:
