• 測量学そくりょうがく
  nounSurveying as a subject of study — the discipline of land surveying — rather than the practical activity itself. A less common word; choose it when talking about the field, not a surveying job.
• 回視かいし
  noun, suru verbThe sense of 'surveying' meaning to look around or let one's eyes travel over a scene, with no measuring involved. A less common word, and seldom the one you want unless that visual sense is meant.
