What does selenographical mean?
Selenographical is an adjective meaning connected with the mapping or detailed representation of the Moon. The word belongs to the vocabulary of historical astronomy and cartography, especially the period when observers produced charts and maps by studying the Moon visually and recording its craters, mountains, and other surface features. A selenographical map therefore represents the Moon as seen and catalogued by an observer rather than as an image produced by modern spacecraft or photographic surveying. The term can also describe observations, records, or other work intended to document lunar geography. Although “selenographic” is the more common contemporary form, “selenographical” remains intelligible and is especially associated with older scientific literature. Its specialized character gives it a scholarly and historical flavour, while its direct association with the Moon makes it useful when discussing the development of lunar cartography.
