The Association of Archaeological Illustrators and Surveyors (AAI&S) was formed in Britain in 1978 and is now an international body for those engaged in all aspects of professional archaeological illustration and survey. It is an independent body funded through membership subscription. As a professional body, one of the main aims of the AAI&S is to set standards within the profession and to promote these standards within the archaeological world at large. The Association's membership reflects the wide range of specialist skills and disciplines which are required from today's professional Archaeological Illustrators and Surveyors. The Association also endeavors to act as an appropriate platform from which members can exchange ideas and examine new directions.
