Archaic literary noun or suru-verb for gazing into the distance or surveying a broad scene. Not used in modern everyday Japanese.
古い詩文では「瞻望」が遠くを見渡す意味で使われる。
In old poetry and prose, 瞻望 is used to mean looking out over a distance.
展望 is the modern common word for 'view' or 'outlook', both literal and figurative, while 瞻望 is an archaic literary term for physically gazing afar.
Archaic kanji spelling; the word itself is rare and literary.
The exact derivation is uncertain; the kanji 瞻 (look up, gaze) and 望 (hope, view) combine to suggest looking into the distance, but the word is not in common use.
