Description of this data

We have demonstrated that maps created using multiple global surveys can be of higher fidelity than those made from one global survey. Our results indicate that we can detect strong contrasts that are two-fifths the size of the spectrometer field of view. We also find that algorithms which select a single observation (or spot) per facet are better at reproducing spectral contrasts and the shapes of spatial borders between regions than algorithms that average over the available observations. Increasing the facet count of the shape model improves map fidelity in our simulations, however, further increases in fidelity over those observed (with the 196 K facet shape model and the OVIRS spectrometer) are likely to be insignificant
