Celestial cartography, uranography,
astrography or star cartography is the aspect of
astronomy
Astronomy is a natural science that studies celestial objects and the phenomena that occur in the cosmos. It uses mathematics, physics, and chemistry in order to explain their origin and their overall evolution. Objects of interest includ ...

Etymology
The word "uranography" derived from the
Greek "ουρανογραφια" (
Koine Greek
Koine Greek (, ), also variously known as Hellenistic Greek, common Attic, the Alexandrian dialect, Biblical Greek, Septuagint Greek or New Testament Greek, was the koiné language, common supra-regional form of Greek language, Greek spoken and ...
''ουρανος'' "sky, heaven" + ''γραφειν'' "to write") through the
Latin
Latin ( or ) is a classical language belonging to the Italic languages, Italic branch of the Indo-European languages. Latin was originally spoken by the Latins (Italic tribe), Latins in Latium (now known as Lazio), the lower Tiber area aroun ...
''"uranographia"''. In Renaissance times, ''Uranographia'' was used as the book title of various
celestial atlases. During the 19th century, "uranography" was defined as the "description of the heavens". Elijah H. Burritt re-defined it as the "geography of the heavens". The German word for uranography is "''Uranographie''", the French is "''uranographie''" and the Italian is "''uranografia''".

, is concerned with precise measurements of the location of celestial bodies in the celestial sphere and their kinematics relative to a reference frame on the celestial sphere. In principle, astrometry can involve such measurements of planets, stars, black holes and galaxies to any celestial body.
Throughout human history, astrometry played a significant role in shaping our understanding of the structure of the visible sky, which accompanies the location of bodies in it, hence making it a fundamental tool to celestial cartography.
Star catalogues
A determining fact source for drawing star charts is naturally a star table. This is apparent when comparing the imaginative "star maps" of ''Poeticon Astronomicon'' – illustrations beside a narrative text from the antiquity – to the star maps of
Johann Bayer, based on precise star-position measurements from the ''
Rudolphine Tables'' by
Tycho Brahe
Tycho Brahe ( ; ; born Tyge Ottesen Brahe, ; 14 December 154624 October 1601), generally called Tycho for short, was a Danish astronomer of the Renaissance, known for his comprehensive and unprecedentedly accurate astronomical observations. He ...
