“…This inclusion considerably increases the range of reflectances that can be recorded and is particularly important as Krinov (1947) showed that some plants have extended differences in this area. Buried archaeological features are often identified only because they cause anomalous growth stresses in the crops that overlie them and Riley (1946) discussed this effect. A now invisible and silted ditch which is cut into, say, a gravel subsoil might well have a different moisture capacity characteristic to the surrounding undisturbed material and any crop that overlies it will have a different, and possibly longer, growth cycle than normal.…”

The recognition of subsurface soil disturbances that have no surviving surface displacement often depends on an anomalous growth of the crop that overlies them. These disturbances are sometimes evidences of man's past activities. The very slight differentials of colour and height in growing crops are frequently difficult to record through a normal film and filter combination. In order to test the capacity of the multispectral technique, a four camera sensor was flown over archaeological sites in central southern England in the summer of 1970. Known sites were used in various geological settings, producing growth marks of differing characteristics. The sensor included the near infrared and this showed distinct advantages at the early stages of cereal growth.

“…The First World War also provided the opportunity for soldiers and air crew to operate in parts of the world, especially the Middle East, where they could experiment without continual bombardment (Bewley 1997;Deuel 1969). In the first half of the twentieth century the basic rules of aerial reconnaissance and more importantly air photo interpretation were established (Hamshaw 1920;Crawford 1928, and1929;Riley 1946). In the two World Wars in the twentieth century the achievements of aerial reconnaissance and subsequent air photo interpretation are well known (Nesbit 1996).…”

Aerial Survey has developed its approaches and techniques over the past one hundred years so that it now integrates the results of reconnaissance with interpretative, analytical extensive surveys. This short article introduces the background to English Heritage's National Mapping Programme (NMP) and explains the philosophy and approach behind it.In the 1980s there was a debate over the nature of the evidence derived from aerial photographs and NMP has devised a classification and recording system which meets most of the needs of users, be they national organisations, county archaeologists, commercial contractors or university researcher. The maps and records produced by NMP are used to further our understanding of past human settlement in England, at both the individual site level but also in regional or landscape contexts. This article provides an overview of the current progress of NMP and acts as an entreé for future articles in this journal dealing with specific landscapes.

On the basis of archaeological and alluvial records, this paper presents the first spatial analysis of artefacts in relation to the evolution of the Rhine River, at the Gallo-Roman site of Oedenburg, during the first four centuries AD. The dataset consisted of several thousand Roman artefacts found by pedestrian prospecting over the last twenty years, over half of which were coins. This dataset was used together with high-resolution topography and geomagnetic mapping, to reconstruct settlement evolution, both on the terrace and in the floodplain. A comprehensive monetary chart has been compiled for the Oedenburg site, which highlights four major phases of settlement. These results provide a possible causal link connecting historical factors and alluvial events with intra-site evolution. Therefore, while changes observed during Phases I (until AD 68), II (AD 69 to AD 180) and III (AD 180 to AD 295) seem largely related to historical and societal events, Phase IV (AD 295 to AD 402) shows patterns of abandonment of the lower part of the floodplain that may well be related to an unusually humid period in the fourth century. These results are set in a broader context, from the Rhine catchment area to the Alps, and are in agreement with the wet conditions also documented in alluvial, lacustrine, geomorphological and palynological records in Germany (Lahn River, Lake Constance, Lake Nussbaumen, Kaisersthul area and the Black Forest). Studying the intra-site spatial distribution of artefacts with high temporal constraints, at a long-lived site with contrasted topography, opens new avenues for the detection of discreet events such as a higher water table, affecting only the lower zone.
