About this deal

Roman roads remained in use as trunk roads for centuries after the Romans withdrew from Britain in 410 AD. Systematic construction of paved highways did not resume in England until the 18th century.

In addition to contract photography, the collection occasionally holds cover obtained by the national survey departments, and other aid agencies such as the Canadian International Development Agency.A small-scale guide to this photography is included in the DOS Annual Reports from 1951 to 1984, to be held by The National Archives (TNA). Other photography in the collection is shown on non-DOS cover diagrams or sortie plots produced by the originator of the photography. Summary diagrams for each country illustrate the location of all photography. The principal points of photos used in the mapping are shown and numbered on almost all DOS 1:50 000–1:125 000 scale topographic maps and provide accurate indications of the location of individual photos. Air photo mosaics and print laydowns (uncontrolled mosaics produced as map substitutes on standard sheetlines in advance of the regular mapping) are archived at the National Collection of Aerial Photography.
