Air Photograph Interpretation by RCHME at Hunts Hill Farm, near Upminster, 1994 - EEX63963

A level 3 photogrammetric survey was carried out by the RCHME APU on the area of Hunts Hill Farm, near Upminster, Essex (centred at:- TQ 564 831). The 1:2500 scale survey was of an area 1km X 0.7km, and was carried out at the request of the Archaeology and Local History Centre, London Borough of Newham, who had excavated part of the area in advance of gravel extraction.The purpose of the survey was to produce 1:2500 scale photogrammetric plans (in the form of overlays to 1:2500 OS base maps) of all plough-levelled archaeological features visible on aerial photographs in the survey area. For the purposes of this survey, plough-levelled features are defined as those which have been recorded by aerial photography as differentially coloured or textured marks in bare plough-soil, arable crops, grass or any other form of vegetation. There were no upstanding earthworks in the survey area. The plans were produced using computer-aided rectification from oblique aerial photographs, and this was achieved through the use of the AERIAL software published by the University of Bradford. Field control was derived from current edition 1:2500 OS base maps, and the accuracy of the plans was +/-0-2m.In December 1994, an additional survey of the periglacial features visible on the air photographs, was requested by the Archaeology and Local History Section of Newham Council. The reason for the request was to aid the evaluation of the final stage of archaeological work on the site. A 1:2500 scale photogrammetric plan was produced of all geological features showing as cropmarks in the area of the original survey. This was in the form of an overlay to the archaeological transcription. Plans were produced by computer aided rectification with an accuracey of +/- 0-3m.Before the survey was undertaken there were no Monarch monument records for this area. No written archaeological interpretation was produced during the survey, and the monument records created by the project are as a result of analysis of the transcription only (the aerial photographs were not re-viewed).The archive is held by the RCHME (Collection UID = 915855) and consists of plans and a short report.
