tools, new advanced technologies are used by planetary geologists Scientists also with these tools, use maps and images that telescopes on Earth (thirty meter telescope) and orbiting telescopes (Hubble) have taken different planetary bodies. The maps and images are stored in the NASA Planetary Data System where tools such as the Planetary Image Atlas help to search for certain items such as geological features including: mountains, ravines, and craters. Features and terms Planetary geology uses a wide variety of standardized descriptor names for features. All planetary feature names recognized by the International Astronomical Union combine one of these names with a possibly unique identifying name. The conventions which decide the more precise name are dependent on which planetary body the feature is on, but the standard descriptors are in general common to all astronomical planetary bodies. Some names have a long history of historical usage, but new must be recognized by the IAU Working Group for Planetary System Nomenclature as features are mapped and described by new planetary missions. This means that in some cases names may change as new imagery becomes available, or in other cases widely adopted informal names changed in line with the rules. The standard names are chosen to consciously avoid interpreting the underlying cause of the feature, but rather to describe only its appearance.
