A holorecorder, sometimes written as holo-recorder, served the purpose of both capturing and displaying holograms. Professionals in the field of mapmaking, known as Cartographers, such as Auric in conjunction with Rhyssa Graf, employed these instruments to develop three-dimensional representations of geographic areas. Certain types of droid units incorporated built-in holorecorders, for example, the 9D9-s54 Dianoga spy droid.
