I should clear up and mention some confusion regarding the map of Eros that was posted here several days ago, because there appears to be a lot of confusion regarding the map john71 posted and comparing the one to the one Gurren posted as well.

The map is obviously not made in equirectangular projection and is designed for a specific UV map projection for that specific model. It must be converted to such a format in order to use it on other models. Nevertheless, the model seems to be decently high quality, although not strictly the best available. Fortunately, we got good results from NASA's NEAR Shoemaker probe.

The map does not appear to be a visible-light map of Eros. Instead, it seems to be either a fictional one (it looks like Hyperion, or maybe a fictional one with a texture similar to a sponge), or a modified topographic map of Eros. In my opinion, it's more likely to be the latter. So this map does not accurately represent the surface of Eros.

In this case, this is mostly NASA's issue, because the texture they provided is wrong. For future reference, I would not take results as "official" or "scientific" unless they appear in a published journal or in a NASA imaging publication (such as the maps of Tempel 1, or Pluto, or the exoplanet pictures), or we have verification of their source (i.e. the maps from CICLOPS, PDS, or Phil Stooke).

Still, it is a nice map and is projected from a different perspective than you usually see.

In any case, the best map of Eros that I know of is the one by Askaniy.

Phoebe texture (upscaled 12k).

False color.

From NASA texture.
