The snowman is a set of three craters, nicknamed "Snowman" by the NASA/Dawn Framing Camera's team members.  TIt is located in the northern hemisphere of Vesta and the two larger craters are about 40 kilometers across.



This dataset includes basemaps and data to do develop a geologic mapping project over the _Snowman_ region of Vesta.



The __coordinate reference system (CRS)__ for this data set is the [IAU_2015:20000041](https://spatialreference.org/ref/iau_2015/200000410/), indicating a [simple cylindrical projection](https://en.wikipedia.org/wiki/Equirectangular_projection) over a sphere with 255 km of radius.
