Roman Britain (Historical Map and Guide): 7

Product Information

Most of the photography used by DOS for mapping, including the RAF and contract cover, is indexed on record reference cover diagrams, generally at 1:500 000 scale. The written catalogue is a Roneodex card index, with one card per film recording: We also have an extensive wiki aimed at the collection of historical information surrounding the road network and its history. By 1991 the last significant, aid-funded mapping projects had been completed by OSD and all survey parties had been disbanded. OSD’s title was changed to OS International and its priorities turned to consultancy, mainly in Eastern Europe, while traditional map production gradually declined. During 2003 and 2004, Ordnance Survey and TNA sought suitable custodians of all parts of the collection and relocated them. The public could access the historical archives again from the end of 2004. Where are the International Collection archives now?

Ordnance Survey of Great Britain, shewing military districts. Sheet 1 (North), Sheet 2 (Central), Sheet 3 (South) The Directorate of Overseas Surveys (DOS) book collection was merged with the Ordnance Survey Library’s collection in 1987. It has since been withdrawn from the library and has relocated to other institutions under the direction of the National Archives. International boundary survey data, maps, correspondence, and files are held by The National Archives. It was Directorate of Overseas Surveys (DOS) practice to show international boundaries on the medium-scale mapping wherever well-defined, and there was enough information to be drawn without significant error. Portrayal of boundaries was agreed with countries concerned, and correspondence with national survey departments provided additional data. HereWeGo is not the best known, but provides both mapping and recent aerial photo coverage. The layers control to access the aerial imagery is in the bottom right corner of the screen Lecture & Seminar Series The Roman roads in Britain were, with Roman aqueducts, and the Roman army, [1] one of the most impressive features of the Roman Empire in Britain.We sell a limited reproduction range of one inch to one mile maps (revised fromthe late 1800s and published in the early years of the 1900s) from our OSmap shop. We alsosell various historical products produced by our licensed Partners. In Britannia, [2] as in other provinces, the Romans constructed a network of paved trunk roads to (surfaced highways). In their nearly four centuries of occupation (43 – 410 AD) they built about 2,000 miles of Roman roads in Britain. They are shown on the Ordnance Survey's Map of Roman Britain.

You can see this functionality in action if you choose one of the One Inch layers from the 1950s-70s. The directions for making pavements given by Vitruvius. The pavement and the via munita were identical in construction, except as regards the top layer. The many existing remains of víae publicae. These are often sufficiently well preserved to show that the rules were, as far as local material allowed, closely followed in practice. 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.

Directorate of Overseas Surveys book collection

A basic scale used on former British territories was 1:50 000. Smaller scales were used in arid lands such as British Somaliland (1:125 000) and parts of Botswana (1:125 000, later 1:100 000). Larger scales (1:25 000) in Mediterranean and Caribbean islands. "Selected" areas, and sometimes whole islands (Malta, Gozo, Bermuda), were mapped at 1:2500 scale (occasionally 1:5000, 1:2400, 1:1200) and, rarely, at 1:500 scale (Male, Stanley). The RGS-IBG collection contains all series produced by the Directorate of Colonial Services (DCS) and its subsequent successors between 1946 and 1999. This includes: Almost all photography of Africa, Aden, Malaya, and Borneo flown between 1946 and 1953 was taken with Fairchild® K17 cameras, and from 1951 with Williamson F49 cameras, both using the same focal length of 152 mm. These were carried in aircraft (mainly Lancasters) of RAF photographic reconnaissance squadrons. The planned scale of photography was 1:30 000, selected as a compromise that would provide specialist departments (geology, forestry, agriculture) with photography that both enabled interpretation of thematic information, and suited topographic mapping. The collection holds approximately 1.5 million monochrome, vertical aerial photographs. Each one is survey-standard and suitable for viewing stereoscopically in 3D. Most are at nominal scale 1:30 000 – 1:60 000 and in 230 mm by 230 mm format. Mostly panchromatic, though there are infrared, monochrome prints, off-colour, infra-red negatives, and a few colour prints. Most of the known network was complete by 180 AD. Its main purpose was to allow the rapid movement of troops and military supplies. It was also vital for trade and the transport of goods.
