The Aerial Archaeology Research Group (AARG) provides a forum for the exchange of ideas and information for all those actively involved in aerial photography, photo interpretation, field archaeology and landscape history. This also includes the use of aerial photography in defining preservation policies for archaeological sites and landscapes.
The Aerial Archaeology Research Group (AARG) began life in 1981 as a small seminar called to discuss ideas raised by Paul Ashbee (then of the University of East Anglia) and David Wilson (of CUCAP).
The critical issue was to examine ways of obtaining archaeological information from existing aerial photographs – problems that now tend to fall within ‘post-reconnaissance’ work. Meetings of that group then continued to be held at least once a year – and those were exciting times.
Computer rectification had become available and allowed, for the first time, rapid mapping of complex features and large areas. This was used by a small number of research students to study different areas of Britain, and many of the early AARG meetings were spent discussing ways of illustrating different kinds of features (see Aerial Archaeology 11) and of methods of classification of the mapped features and their results. The latter is a never-ending quest and recurs at intervals and as new areas (each of which has its own specific problems) are studied or new methods applied (see, for example, papers by Duncan and Redfern in AARGnews 14).
More recently, the annual AARG meetings have become slightly more formal presentations of finished, or ongoing, projects, although our present chairman intends to reintroduce some more open discussion. Presentations have included some of the results from the National Mapping Programme for England (RCHME), and integration of different survey methods (such as comparing results from AP interpretation with geophysics, or adding field-walked data to AP-derived maps). Use of satellite images has been pursued as the special interest of one member but, with the increasing resolution now publicly available, this media is becoming a useful source of archaeological information (see Fowler in AARGnews 9-15, Comfort in AARGnews 14).
As AARG enlarged in size, so it attracted aerial photographers as members and topics have arisen which pursue their interests. The merits of different types of hardware (cameras, films, filters, etc) have been discussed (see Crawshaw AARGnews 8-10; Jones in AARGnews 16) and our meetings tend to include an informal session at which members can show a selection of their latest photographs. Current interest, raised as an important post-reconnaissance question, asks whether the traditional archaeological oblique photographs provide reliable data on which to base archaeological survey. This continues to form part of discussions at the annual conferences.
Extending into Eastern Europe
With the dropping of flying restrictions in eastern Europe, we have recently welcomed many members from ex-soviet bloc countries and AARG has played a prominent role in helping to establish programmes of flying and recording. A conference was held at Kleinmachnow, Berlin in 1994 (ref) and was followed in 1996 by a training week in Hungary. That week provided airborne experience for more than 20 ‘students’ who were also introduced to the basics of photo interpretation, mapping and analysis of those results. A successful follow-up training week was held in Leszno, Poland, in the first week of July 1998, where some 20 inspectors and archaeologists from Poland and elsewhere recieved training in aerial photography and air photo mapping.
AARG has a small, but increasing, number of members from, or working in, other parts of the world and AARGnews has included summaries of work in Israel (Riley, issue 5), Turkey (Summers, issue 7), and Jordan (Kennedy, issue 12). Most recently we have been fortunate enough to have Kevin Jones from New Zealand as a speaker at AARG 1996 (see also his papers in AARGnews 13-14, 16).
